Is it testworthy, or is it untestworthy?

There’s a fine line between optimizations and experiments. Testing something is an exercise in curiosity, whereas optimizing a thing is an act of certainty.

If we know the outcome of a given activity before we perform that activity, we’re in optimization territory. For example, if you’ve discovered a load of orphaned pages, then the act of internally linking to those pages is highly likely to result in a positive outcome. We can deem this scenario, “untestworthy” (yes, I know that’s actually a word).

But, as we’ll discuss here, SEO includes a vast array of activities where the outcomes of our work are either uncertain or difficult to predict. Think about the last time you experienced a site migration. Were you certain that the new site would perform better than the original? This might be a scenario that we’ll deem, “testworthy.”

In short, a testworthy activity is one where we don’t know the ending until we measure our outcomes with data.

Measuring our SEO tests

The step-by-step measurement processes and techniques for conducting SEO experiments fall outside the scope of this article, so if you’re reading this and asking yourself, “how exactly do I run an SEO experiment from start to finish?”, here are a couple links to resources that can assist you in learning the nitty-gritty specifics of setting up and measuring SEO experiments:

For each of the experiments below, I will assume a time-based measurement technique. Although some of the ideas here can be tested using an A/B split testing technique, not all of them can.

Curious about time-based techniques? I cover them in detail in this guide.

A word on statistical significance

One final note to remember. Statistical significance, i.e. when your results can be confidently attributed to your testing criteria, is a sexy concept, but one sobering reality of SEO testing is that statistical significance can only be achieved through rigorously advanced split testing.

Time-based SEO experiments provide us with directional learnings, not absolute conclusions. Advantages of experimenting in this way include the ability to react more quickly, use up fewer resources, and the flexibility to experiment in nearly all search environments where split testing cannot.

Here’s one way to visualize how non-significant tests remain valuable. On the left end of the spectrum, there are the crapshoot experiments: low confidence, low investment initiatives that provide less reliable insights. Further to the right, we can begin categorizing experiments according to higher confidence intervals and higher resource investments. Somewhere in the middle, there are a great many SEO tests that provide directional insights, even when our directional insights aren’t guaranteed with the promise of scientific certainty.

With this in mind, I’ve put together a list of five inconspicuous SEO tests that appear “untestworthy,” but are actually SEO tests disguised as optimizations.

Test in disguise #1: URL switching

Two handwritten URLs showing an example change.

A URL switch test is really very similar to SEO title testing. The idea behind URL switch tests is simple: like page titles, we know that URLs are heavily weighted ranking factors, so if we find that there are URLs that look under-optimized or misaligned with our target terms and search intents, then we can build a hypotheses for testing a new URL and redirecting the original URL.

Some of you might be silently blowing a fuse right about now, and for good reason. URL switch tests can be very risky. If your original URL has already generated a substantial number of links (internal or external) I would exercise extreme caution before running a URL switch test.

As you probably know by now, redirects have the potential to backfire, and if your test fails, cannot be rolled back to the original URL variant as easily as a title test can be rolled back.

But this shouldn’t scare you if you are running a URL switch test in lower-risk scenarios. I have seen many successful URL switch tests in scenarios where the target URL was either freshly-launched, had too few links pointing to it, or where the URL was so ineffective that an experiment was justifiably worth the risk.

How to run a URL switch test

Check the URL’s current traffic levels. Higher traffic levels = higher risk.
Check the URL’s internal and external links. Internal links can be updated, but external links can still lose strength as you pass them through a 302/301.
If the risk is within your level of tolerability, clarify what your new hypothesis and URL test variation will be.
Change the URL from the control URL to the variation URL.
Add a 302 temporary redirect from the control to the variation, submit the URL for re-indexation in Google Search Console (GSC), and benchmark the date that this is completed on.
Wait 2-6 weeks to measure the clicks before vs. clicks after for equal time durations and days of the week in GSC.
- For example: If your measurement period (after data) begins on a Thursday and ends on a Sunday, then I recommend comparing with an equivalent time duration in GSC that also begins on a Tuesday and ends on a Sunday just prior to the experiment launch date (before data). For most websites, the click patterns on weekends will be lower than on weekdays. Using the same days of the week and time durations allows you to control for these differences in daily click patterns.
- The optimal time-range is situation-dependent. Pages that generate high click volumes can be measured closer to the two-week time-frame, while pages that generate lower click-volumes will need to run longer.
- Caution: If the risk to this page is high, you may want to check in periodically during the first few days to make sure that performance doesn’t drop unexpectedly.
When measuring performance, use the “compare URLs” feature in GSC. This lets you check both the control URL and the variation URL simultaneously.
After you’ve gathered enough data to make a directionally-sound judgment call about which URL performs better, do one of the following:
- If the new variation performed better: Change the 302 temporary redirect to a 301 permanent redirect and update all internal links to reflect the new URL.
- If the original control URL performed better: Remove the 302 redirect. [Optional: you may want to add a new redirect from the failed variation URL back to the original control URL to speed up the re-indexation process.]
Resubmit the final URL in Google Search Console and periodically monitor the performance after the test has ended to ensure that performance remains positive.

Test in disguise #2: Content refreshes

Illustration of two pages, one the control and one with a variance.

Isn’t a content refresh a given? We know that refreshing content is good for SEO, so why does it need testing?

Yes, content refreshes are incredibly important and this is an activity that has been proven successful time and time again. However, not every content refresh yields positive results.

Even though it isn’t the norm, content refresh projects can occasionally result in traffic losses, and perhaps equally frustrating, many refresh projects can turn out neutral results. This means that all of that precious time and energy that we spent rewriting and republishing a piece of content failed to produce the outcome that we intended.

For these reasons, it’s important to figure out if our investments in these projects have achieved their desired positive outcomes or not. That’s where SEO testing comes into play.

How to run a content refresh SEO test

Perform your content refresh project exactly as you otherwise would, according to your own content team’s workflow. Make sure to save all of the original files, in case you need to revert back to the original content.
On the date of republication, submit the page URL to Google Search Console to be re-indexed and benchmark the date.
Wait 2-6 weeks to measure the clicks before vs. clicks after in GSC.
After you’ve gathered enough data to make a directionally-sound judgment call about which URL performs better, do one of the following:
- If the variation performed better: Congrats! Report the results to your team and keep the change.
- If the control performed better: Reinstate the original content and files. Then, re-index the page and continue monitoring performance to look for rebounding traffic.

Test in disguise #3: Section rearrangement

Illustration of two pages, one the control and one with rearranged features.

A section rearrange test is just what it sounds like. The hypothesis for these experiments is that if we can reprioritize some of the on-page content, elements, or components, then we might be able to influence the page’s rankings and traffic coming in.

This can work particularly well, if the page section that addresses our audiences’ main search intents is either buried deep below the fold, or if it requires extra steps for the user to access that content.

For simplicity’s sake, let’s use the example keyword: “email ideas for cold outreach.”

This keyword appears to have a lot of demand from users who are looking for specific email templates and phrasings that they can use in their outreach campaigns.

Now, let’s assume that you’ve got a blog post on this exact topic, but the exact email templates and scripts that users are searching for are buried at the end of your posts, well past a dozen other sections of content that don’t satisfy their search demand. This might be a great case for running a section rearrange test.

The idea is, if you can reprioritize those pieces of information that users are looking for from the bottom of your page to the top of your page, Google is likely to notice the prioritized content as a better match for users to quickly access the information they want. Thus, rankings and traffic may improve in the same way they might improve with a content refresh project.

Added bonus: it’s faster than rewriting new content!

How to run a section rearrange SEO test

Look for pages that are underperforming, and that have addressed a users’ primary search intent somewhere deep within the page.
Rearrange the page sections in a way that might create a better experience or flow for the readers.
Launch the new page (but remember to save the original control page files), re-index in Google Search Console, and benchmark the date.
Wait 2-6 weeks to measure the clicks before vs. clicks after in GSC.
After you’ve gathered enough data to make a directionally-sound judgment call about which URL performs better, do one of the following:
- If the variation performed better: Congrats! Report the results to your team and keep the changes.
- If the control performed better: Reinstate the original content and files. Then, re-index the page and continue monitoring performance to look for rebounding traffic.

Test in disguise #4: Content removal

Illustration of two pages, one the control and one with a content feature removed.

This test is the SEO-equivalent of what CRO professionals call “a takeaway test.”

In digital marketing, there are times when less really is more, so the idea for this experiment is, if we just trim out certain items — whether those might be page elements, or less-helpful content sections — then the removal process could lend itself to creating a tighter, stronger webpage.

In a CRO-driven takeaway experiment, a CRO professional might notice certain elements that distract users or get in the way of a conversion path.

This concept works just a little bit differently for SEO if our goal is to improve rankings and traffic performance. For SEO, content removal experiments are just a matter of “trimming the fat” from our content and page elements.

When analyzing your top pages, ask yourself if you see any sections, paragraphs, or sentences which deviate from the information that the search audience really came for. You might be surprised to see how much of the content we create is actually worthless for our users.

How to run a content removal SEO test

Scan for high-value pages and posts that may be hitting a wall with rankings and traffic performance.

Make sure to analyze the top keywords and SERPs so that you can get very clear on which primary and secondary search intents the users predominantly wish to see and read about.
Scan your page’s content with a dose of radical honesty to look for content that diverges from the information that you might want to see if you were a reader.
If your investigation turns up content and/or elements that don’t help the users, remove them and make sure to save the original control page files, just in case the experiment results are negative.
Launch the new page, re-index in Google Search Console, and benchmark the date.
Wait 2-6 weeks to measure the clicks before vs clicks after in GSC.
After you’ve gathered enough data to make a directionally-sound judgment call about which URL performs better, do one of the following:
- If the variation performed better: Congrats! Report the results to your team and keep the changes.
- If the control performed better: Reinstate the original content and files. Then, re-index the page and continue monitoring performance to look for rebounding traffic.

Test in disguise #5: Featured snippets

This activity is one of my all-time favorites.

Treating our featured snippet answers like an SEO test is one of the ways that my teams have been able to accrue competitively high volumes of traffic and clicks in recent years.

When our team began to treat our featured snippets as experiments, rather than optimizations, we were able to learn much more about how to write better answers, and we were able to create processes for scaling up to higher quantities of featured snippet experiments. This meant more “at bats” for acquiring the answer box rankings, which meant faster traffic growth.

Much has already been covered about how to optimize for featured snippets. I’ll simply add a process for testing your featured snippet copy.

What’s more, featured snippet tests are one of the rare instances where statistical significance is undeniably attainable because the success measurement is binary. Either your experiment resulted in acquiring the featured snippet, or it did not. (Caveat: Some longer tail featured snippets may also be impacted by your experiments, but the impacts are generally negligible if you are targeting a strong primary keyword.)

How to run featured snippet tests

Identify opportunities where featured snippets are appearing in the SERPs, and where one of your pages ranks within the top 5 positions but is not occupying the answer box. (Tip: some of the current rank tracking solutions such as STAT make featured snippet identification much easier.)
Sort and prioritize featured snippet opportunities according to the opportunities that represent the highest value to your website. I recommend considering the traffic’s audience and conversion potential alongside the potential search volume.
Rewrite the portion of your article where the featured snippet is being targeted. This step is another one where the full context of featured snippet practices span outside the scope of this article, so you may want to check out resources like this if you’re not already familiar with featured snippet rewriting.
Periodically check in on your target answer box(s) and traffic over the next several weeks.
If at first you don’t succeed, test again! The great part about answer box testing is that you rarely need to revert to your control, and you can keep swinging until you hit the home run. In some cases, we’ve had to make as many as ten or more rewrite attempts before successfully capturing the featured snippet.
Repeat this process to run more experiments the remaining featured snippet opportunities that were identified in step one.

More SEO tests in disguise

This list is far from exhaustive.

As I alluded to earlier in the piece, I think that just about anything which requires measurement is a form of testing to some degree, regardless of whether or not this activity can be measured to true statistical significance.

If your team is investing any serious resources into activities like core web vitals, internal linking, E-A-T enhancements, site migrations, Schema markup, or UX changes, it’s usually wise to do a retrospective before and after analysis on whether or not that investment yielded a positive payoff.

Stacking up those experiments to figure out where your bets are paying off, versus where they are not paying off will start to steer your strategy and SEO knowledge toward more profitable outcomes.

How marketing automation can simplify operations and increase efficiency

Understanding the Change

Marketing automation has evolved significantly over time, from basic email marketing campaigns to sophisticated platforms that can manage entire marketing strategies. This progress has been fueled by advances in technology, particularly artificial intelligence (AI) and machine learning, making automation smarter and more adaptable.

One of the main reasons for this shift is the vast amount of data available to marketers today. From understanding customer demographics to analyzing behavior, the sheer volume of data is staggering. Marketing automation platforms use this data to create highly personalized and targeted campaigns, allowing businesses to connect with their audience on a deeper level.

The Emergence of AI-Powered Automation

In the future, AI-powered automation will play an even bigger role in marketing strategies. AI algorithms can analyze huge amounts of data in real-time, helping marketers identify trends, predict consumer behavior, and optimize campaigns as they go. This agility and responsiveness are crucial in today’s fast-moving digital world, where opportunities come and go in the blink of an eye. For example, we’re witnessing the rise of AI-based tools from AI website builders, to AI logo generators and even more, showing that we’re competing with time and efficiency.

Combining AI-powered automation with WordPress management services streamlines marketing efforts, enabling quick adaptation to changing trends and efficient management of online presence.

Moreover, AI can take care of routine tasks like content creation, scheduling, and testing, giving marketers more time to focus on strategic activities. By automating these repetitive tasks, businesses can work more efficiently, leading to better outcomes. AI can create social media ads tailored to specific demographics and preferences, ensuring that the content resonates with the target audience. With the help of an AI ad maker tool, businesses can efficiently produce high-quality advertisements that drive engagement and conversions across various social media platforms.

Personalization on a Large Scale

Personalization has always been important in marketing, and automation is making it possible on a larger scale. By using AI and machine learning, marketers can create tailored experiences for each customer based on their preferences, behaviors, and past interactions with the brand.

This level of personalization not only boosts customer satisfaction but also increases engagement and loyalty. When consumers feel understood and valued, they are more likely to become loyal customers and brand advocates. As automation technology continues to evolve, we can expect personalization to become even more advanced, enabling businesses to forge deeper connections with their audience. As your company has tiny homes for sale California, personalized experiences will ensure each customer finds their perfect fit, fostering lasting connections.

Integration Across Channels

Another trend shaping the future of marketing automation is the integration of multiple channels into a cohesive strategy. Today’s consumers interact with brands across various touchpoints, from social media and email to websites and mobile apps. Marketing automation platforms that can seamlessly integrate these channels and deliver consistent messaging will have a competitive edge. When creating a comparison website it’s important to ensure that the platform effectively aggregates data from diverse sources and presents it in a user-friendly manner, empowering consumers to make informed decisions.

Omni-channel integration not only betters the customer experience but also provides marketers with a comprehensive view of the customer journey. By tracking interactions across channels, businesses can gain valuable insights into how consumers engage with their brand, allowing them to refine their marketing strategies for maximum impact. Lastly, integrating SEO services into omni-channel strategies boosts visibility and helps businesses better understand and engage with their customers across different platforms.

The Human Element

While automation offers many benefits, it’s crucial not to overlook the human aspect of marketing. Despite advances in AI and machine learning, there are still elements of marketing that require human creativity, empathy, and strategic thinking.

Successful marketing automation strikes a balance between technology and human expertise. By using automation to handle routine tasks and data analysis, marketers can focus on what they do best – storytelling, building relationships, and driving innovation.

Conclusion

The future of marketing automation looks promising, offering improved efficiency and results for businesses of all sizes.

As AI continues to advance and consumer expectations change, automation will play an increasingly vital role in keeping businesses competitive.

By embracing automation technologies, marketers can simplify processes, deliver more personalized experiences, and ultimately, achieve their business goals more effectively than ever before.

Will Google Buy HubSpot? | Content Marketing Institute

Why Marketers Should Care About Google’s Potential HubSpot Acquisition

Google + HubSpot. Is it a thing?

This week, a flurry of news came down about Google’s consideration of purchasing HubSpot.

The prospect dismayed some. It delighted others.

But is it likely? Is it even possible? What would it mean for marketers? What does the consideration even mean for marketers?

Well, we asked CMI’s chief strategy advisor, Robert Rose, for his take. Watch this video or read on:

Why Alphabet may want HubSpot

Alphabet, the parent company of Google, apparently is contemplating the acquisition of inbound marketing giant HubSpot.

The potential price could be in the range of $30 billion to $40 billion. That would make Alphabet’s largest acquisition by far. The current deal holding that title happened in 2011 when it acquired Motorola Mobility for more than $12 billion. It later sold it to Lenovo for less than $3 billion.

If the HubSpot deal happens, it would not be in character with what the classic evil villain has been doing for the past 20 years.

At first glance, you might think the deal would make no sense. Why would Google want to spend three times as much as it’s ever spent to get into the inbound marketing — the CRM and marketing automation business?

At a second glance, it makes a ton of sense.

I don’t know if you’ve noticed, but I and others at CMI spend a lot of time discussing privacy, owned media, and the deprecation of the third-party cookie. I just talked about it two weeks ago. It’s really happening.

All that oxygen being sucked out of the ad tech space presents a compelling case that Alphabet should diversify from third-party data and classic surveillance-based marketing.

Yes, this potential acquisition is about data. HubSpot would give Alphabet the keys to the kingdom of 205,000 business customers — and their customers’ data that almost certainly numbers in the tens of millions. Alphabet would also gain access to the content, marketing, and sales information those customers consumed.

Conversely, the deal would provide an immediate tip of the spear for HubSpot clients to create more targeted programs in the Alphabet ecosystem and upload their data to drive even more personalized experiences on their own properties and connect them to the Google Workspace infrastructure.

When you add in the idea of Gemini, you can start to see how Google might monetize its generative AI tool beyond figuring out how to use it on ads on search results pages.

What acquisition could mean for HubSpot customers

I may be stretching here but imagine this world. As a Hubspoogle customer, you can access an interface that prioritizes your owned media data (e.g., your website, your e-commerce catalog, blog) when Google’s Gemini answers a question).

Recent reports also say Google may put up a paywall around the new premium features of its artificial intelligence-powered Search Generative Experience. Imagine this as the new gating for marketing. In other words, users can subscribe to Google’s AI for free, but Hubspoogle customers can access that data and use it to create targeted offers.

The acquisition of HubSpot would immediately make Google Workspace a more robust competitor to Microsoft 365 Office for small- and medium-sized businesses as they would receive the ADDED capability of inbound marketing.

But in the world of rented land where Google is the landlord, the government will take notice of the acquisition. But — and it’s a big but, I cannot lie (yes, I just did that). The big but is whether this acquisition dance can happen without going afoul of regulatory issues.

Some analysts say it should be no problem. Others say, “Yeah, it wouldn’t go.” Either way, would anybody touch it in an election year? That’s a whole other story.

What marketers should realize

So, what’s my takeaway?

It’s a remote chance that Google will jump on this hard, but stranger things have happened. It would be an exciting disruption in the market.

The sure bet is this. The acquisition conversation — as if you needed more data points — says getting good at owned media to attract and build audiences and using that first-party data to provide better communication and collaboration with your customers are a must.

It’s just a matter of time until Google makes a move. They might just be testing the waters now, but they will move here. But no matter what they do, if you have your customer data house in order, you’ll be primed for success.

5 Psychological Tactics to Write Better Emails

5 Psychological Tactics to Write Better Emails

Welcome to Creator Columns, where we bring expert HubSpot Creator voices to the Blogs that inspire and help you grow better.

I’ve tested 100s of psychological tactics on my email subscribers. In this blog, I reveal the five tactics that actually work.

You’ll learn about the email tactic that got one marketer a job at the White House.

You’ll learn how I doubled my 5 star reviews with one email, and why one strange email from Barack Obama broke all records for donations.

5 Psychological Tactics to Write Better Emails

Imagine writing an email that’s so effective it lands you a job at the White House.

Well, that’s what happened to Maya Shankar, a PhD cognitive neuroscientist. In 2014, the Department of Veterans Affairs asked her to help increase signups in their veteran benefit scheme.

Maya had a plan. She was well aware of a cognitive bias that affects us all—the endowment effect. This bias suggests that people value items higher if they own them. So, she changed the subject line in the Veterans’ enrollment email.

Previously it read:

Veterans, you’re eligible for the benefit program. Sign up today.

She tweaked one word, changing it to:

Veterans, you’ve earned the benefits program. Sign up today.

This tiny tweak had a big impact. The amount of veterans enrolling in the program went up by 9%. And Maya landed a job working at the White House

Boost participation email graphic

Inspired by these psychological tweaks to emails, I started to run my own tests.

Alongside my podcast Nudge, I’ve run 100s of email tests on my 1,000s of newsletter subscribers.

Here are the five best tactics I’ve uncovered.

1. Show readers what they’re missing.

Nobel prize winning behavioral scientists Daniel Kahneman and Amos Tversky uncovered a principle called loss aversion.

Loss aversion means that losses feel more painful than equivalent gains. In real-world terms, losing $10 feels worse than how gaining $10 feels good. And I wondered if this simple nudge could help increase the number of my podcast listeners.

For my test, I tweaked the subject line of the email announcing an episode. The control read:

“Listen to this one”

In the loss aversion variant it read:

“Don’t miss this one”

It is very subtle loss aversion. Rather than asking someone to listen, I’m saying they shouldn’t miss out. And it worked. It increased the open rate by 13.3% and the click rate by 12.5%. Plus, it was a small change that cost me nothing at all.

Growth mindset email analytics

2. People follow the crowd.

In general, humans like to follow the masses. When picking a dish, we’ll often opt for the most popular. When choosing a movie to watch, we tend to pick the box office hit. It’s a well-known psychological bias called social proof.

I’ve always wondered if it works for emails. So, I set up an A/B experiment with two subject lines. Both promoted my show, but one contained social proof.

The control read: New Nudge: Why Brands Should Flaunt Their Flaws

The social proof variant read: New Nudge: Why Brands Should Flaunt Their Flaws (100,000 Downloads)

I hoped that by highlighting the episode’s high number of downloads, I’d encourage more people to listen. Fortunately, it worked.

The open rate went from 22% to 28% for the social proof version, and the click rate, (the number of people actually listening to the episode), doubled.

3. Praise loyal subscribers.

The consistency principle suggests that people are likely to stick to behaviours they’ve previously taken. A retired taxi driver won’t swap his car for a bike. A hairdresser won’t change to a cheap shampoo. We like to stay consistent with our past behaviors.

I decided to test this in an email.

For my test, I attempted to encourage my subscribers to leave a review for my podcast. I sent emails to 400 subscribers who had been following the show for a year.

The control read: “Could you leave a review for Nudge?”

The consistency variant read: “You’ve been following Nudge for 12 months, could you leave a review?”

My hypothesis was simple. If I remind people that they’ve consistently supported the show they’ll be more likely to leave a review.

It worked.

The open rate on the consistency version of the email was 7% higher.

But more importantly, the click rate, (the number of people who actually left a review), was almost 2x higher for the consistency version. Merely telling people they’d been a fan for a while doubled my reviews.

4. Showcase scarcity.

We prefer scarce resources. Taylor Swift gigs sell out in seconds not just because she’s popular, but because her tickets are hard to come by.

Swifties aren’t the first to experience this. Back in 1975, three researchers proved how powerful scarcity is. For the study, the researchers occupied a cafe. On alternating weeks they’d make one small change in the cafe.

On some weeks they’d ensure the cookie jar was full.

On other weeks they’d ensure the cookie jar only contained two cookies (never more or less).

In other words, sometimes the cookies looked abundantly available. Sometimes they looked like they were almost out.

This changed behaviour. Customers who saw the two cookie jar bought 43% more cookies than those who saw the full jar.

It sounds too good to be true, so I tested it for myself.

I sent an email to 260 subscribers offering free access to my Science of Marketing course for one day only.

In the control, the subject line read: “Free access to the Science of Marketing course”

For the scarcity variant it read: “Only Today: Get free access to the Science of Marketing Course | Only one enrol per person.”

130 people received the first email, 130 received the second. And the result was almost as good as the cookie finding. The scarcity version had a 15.1% higher open rate.

Email A/B test results

5. Spark curiosity.

All of the email tips I’ve shared have only been tested on my relatively small audience. So, I thought I’d end with a tip that was tested on the masses.

Back in 2012, Barack Obama and his campaign team sent hundreds of emails to raise funds for his campaign.

Of the $690 million he raised, most came from direct email appeals. But there was one email, according to ABC news, that was far more effective than the rest. And it was an odd one.

The email that drew in the most cash, had a strange subject line. It simply said “Hey.”

The actual email asked the reader to donate, sharing all the expected reasons, but the subject line was different.

It sparked curiosity, it got people wondering, is Obama saying Hey just to me?

Readers were curious and couldn’t help but open the email. According to ABC it was “the most effective pitch of all.”

Because more people opened, it raised more money than any other email. The bias Obama used here is the curiosity gap. We’re more likely to act on something when our curiosity is piqued.

Email example

Loss aversion, social proof, consistency, scarcity and curiosity—all these nudges have helped me improve my emails. And I reckon they’ll work for you.

It’s not guaranteed of course. Many might fail. But running some simple a/b tests for your emails is cost free, so why not try it out?

This blog is part of Phill Agnew’s Marketing Cheat Sheet series where he reveals the scientifically proven tips to help you improve your marketing. To learn more, listen to his podcast Nudge, a proud member of the Hubspot Podcast Network.
