Because of its efficiency and cost-effectiveness, real-time bidding (RTB) has become one of the most popular ways to purchase ad inventory online.
But even for experienced marketers, real-time bidding can be a very confusing concept. So let’s break down what RTB is, how it works, and the pros and cons of using it — all while keeping it jargon-free.
In this post, you’ll learn:
Let’s get started.
What is real-time bidding?
Real-time bidding (RTB) is the process by which companies buy and place ads online through automated auctions. Real-time bidding takes the work out of advertising by making it possible for advertisers to place hundreds and thousands of ads online, often in less than a second, without needing to individually reach out to online publishers.
Real-time bidding is the driving force behind most programmatic advertising campaigns. Programmatic advertising is “the automated process of purchasing and selling online ads.” Real-time bidding allows advertisers to automatically buy ad inventory, place the ads online, and get a certain number of impressions in their programmatic advertising campaigns.
⭐Don’t have time to read the entire post? Listen to our podcast below about real-time bidding and programmatic advertising:
In a traditional media buying process, you have to manually buy ads. Let’s say that you find a magazine that serves your buyer persona. You ask for the media kit, choose the ad dimensions that fit your budget, and then buy the ad for a certain amount of time. Once time runs out, the ad is taken down.
Real-time bidding takes out all of that work. You can get space on that magazine and hundreds of others by letting a Demand-Side Platform (DSP) automatically choose the best publishers and ad spaces, then bid on them for you. You set several certain targeting parameters, such as maximum bid price and target audience. These parameters then determine where your ads are placed.
The publisher accepts your ad only if you place the highest bid. But remember: real-time bidding automatically does all the bidding. You don’t have to take any additional steps.
Still confused? No worries. We break down the concept further below.
How does real-time bidding work?
There are several pieces involved in the real-time bidding process. Let’s take a look at each one of them one-by-one before putting it all together.
- Advertiser: The advertiser is the company or brand that wants to place an ad online.
- Demand-Side Platform (DSP): The Demand-Side Platform is the service advertisers use to launch ad campaigns.
- Publisher: The publisher is the website or online property that wants to sell ad spaces, often referred to as “ad inventory.”
- Supply-Side Platform (SSP): The Supply-Side Platform is the service publishers use to make ad inventory available. SSPs run auctions where ad spaces are instantly purchased by the highest bidder. But this can’t happen unless an ad exchange facilitates the transaction.
- Ad Exchanges: The ad exchange connects companies who want to advertise and publishers who want to sell ad space. Ad exchanges carry out the bidding transaction automatically in real time by connecting both Demand-Side Platforms and Supply-Side Platforms.
- Impressions: Impressions refers to the number of times an ad is seen or scrolled past. In the real-time bidding process, advertisers don’t pay for one individual impression, but rather the cost per thousand impressions (CPM).
Now, let’s put it together. How exactly does real-time bidding work?
On the advertiser side, marketers use DSPs to set up their ad campaign and track its performance. Publishers, on the other hand, use Supply-Side Platforms (SSPs) to list their ad inventory and the price they charge. They then meet in the middle at the ad exchange, the marketplace where the real-time bidding actually takes place.
To determine what ad inventory to bid on, advertisers will set targeting parameters. For instance, a brand may only want to target users who are in a specific region or have visited their website recently.
So, advertisers, or specifically their Demand-Side Platforms, evaluate ad potential in real time and decide whether or not to place a bid and how much to bid.
Remember, advertisers set their bid through the Demand-Side Platform, while publishers’ Supply-Side Platform either accept or reject the bid. The prices are negotiated on a cost per thousand impressions, so the advertiser isn’t paying based on uptime or even dimensions. Instead, they’re paying for the amount of times, in thousands, that their ad is seen.
Let’s go through another example of how it works.
Real-Time Bidding Example
Let’s say Silk is a UK-based beauty brand that just launched a new brow line and is running a campaign. They set up their campaign on a Demand-Side Platform (DSP) and are targeting users who regularly shop for makeup products, are located in the Manchester area, and are between 18 to 30 years of age. The brand also wants its ads to only show on sites related to beauty and lifestyle.
A user visits a publisher’s site. The publisher’s Supply-Side Platform (SSP) sends a bid request to the ad exchange, where Silk’s DSP will be evaluating the value of the impression. The DSP will then determine if the user meets the parameters outlined in the campaign. If so, the DSP will submit a bid.
If Silk has the winning bid, the user will see the ad once the page loads. This process happens thousands of times on different webpages during the length of Silk’s ad campaign.
Silk’s paid ads manager will also be monitoring their ad’s performance on the DSP to see if it’s reaching the desired audience, or if the parameters should be adjusted.
Real-Time Bidding Platforms
There are no RTB platforms because real-time bidding is a method of purchasing impressions, not a channel. However, you can use tools that can help you start the real-time bidding process. These tools help you either purchase ad inventory or place ad inventory for sale through RTB.
Below, we break down some platforms you might use if you’re looking to sell or purchase ad inventory online.
Real-Time Bidding Platforms For Advertisers
As an advertiser, you’ll want to find a Demand-Side Platform that allows you to manage several ad campaigns and set specific targeting parameters — down to the user’s most visited websites and preferred brands. Here are a few options:
- AdRoll: Self-serve Demand-Side Platform that’s a good fit for beginners in the programmatic advertising space.
- mediasmart: Self-serve Demand-Side Platform that provides advanced targeting and segmentation capabilities. Good fit if you’ve set up ad campaigns with other tools, such as Google Ads.
- theTradeDesk: Demand-Side Platform that allows you to place ads on multiple devices, including TV ad rolls, online videos, music streaming devices, mobile apps, and publishers across the web. Good fit if you’re planning to advertise across all of these channels.
Real-Time Bidding Platforms for Publishers
If you have ad inventory to sell, then signing up on a Supply-Side Platform is essential to take advantage of the real-time bidding process. You don’t have to speak with any advertisers, negotiate prices, or do any of the manual work that’s typically associated with account management.
Here are a few channels that will allow you to sell ad inventory through real-time bidding:
- Magnite: Supply-Side Platform for large-scale ad inventory sellers who also want to sell ad space through Private Marketplace (PMP) and Programmatic Guaranteed (PG). Good fit if you’re an experienced ad seller that wants to upgrade to a more capable system.
- Index Exchange: Supply-side marketplace that allows you to get started with ad inventory selling on multiple channels, including display, video, mobile, and native. Good fit if you’d like to start selling ad inventory or if you plan to take advantage of all of the available channels.
You can find more SSPs here.
Still not sure whether you should sell or buy ad space through real-time bidding? We go over the pros and cons below.
Real-Time Bidding Pros
With RTB, advertisers can monitor their campaigns easily without relying on vendors. No need to reach out to multiple publishers and ask for reports, you can get them yourself on your DSP.
This also gives marketers the agility to pivot quickly if their campaign isn’t performing as expected. For instance, you might find that switching out one keyword for another may boost your campaign’s performance and align better with the audience you want to reach.
When purchasing ads through RTB, you buy one impression at a time. This means that every time a website visitor or mobile app user visits a publisher’s site, you’re able to assess that person’s particular profile and see if it matches your target audience.
It makes for more accurate targeting as you can ensure your ads are only reaching the right people at the right time.
The precision of the real-time bidding algorithm allows marketers to spend their ad dollars on high-value impressions.
Too often, brands launch marketing campaigns that only reach a portion of their target market, leaving the rest of the budget wasted on users who don’t fit the profile.
In addition, RTB takes much of the manual labor out of the online advertising process, allowing marketers to focus on other efforts.
Real-Time Bidding Cons
Compromised Brand Safety
Where your ad shows up is as important as who sees it. This is because consumers judge brands’ ads based on the surrounding content.
An Ad Colony survey reported that 60% of consumers have a negative perception of brands whose ads appear near inappropriate, hateful, or offensive content. This can be anything from a site that hosts pirated movies to sites promoting hate speech.
Due to the nature of RTB, there is a risk your ad may appear on a site with content you wouldn’t want your brand associated with. However, brands can limit this issue by putting certain keywords and sites on a “deny” list. This protects brands from showing up on webpages or mobile apps that don’t align with their identity.
Potential Ad Fraud
Ad fraud happens when scammers (or any parties with ill intent) try to trick digital ad networks by falsifying impressions and clicks using bots. Obviously, bots aren’t real people — so they aren’t potential buyers you can eventually convert into customers. Because you don’t get to hand-pick publishers through real-time bidding, there’s the very real chance your ad might be seen by bots instead of real people. The rising sophistication of bots can also cause brands to gather inaccurate data on their campaigns.
Some deceitful publishers fabricate impressions to steal from advertisers. One way to combat this is by using a DSP or ad network with fraud detection software.
Real-Time Bidding is the Easiest Way to Increase Brand Awareness
Real-time bidding makes the online advertisement process fast and easy. Marketers can skip the back-and-forth previously associated with ad buying and focus on tracking the results, increasing the ROI from your campaigns and empowering your brand to grow better.

How We Increased a Client’s Leads by 384% in Six Months by Focusing on One Topic Cluster [Case Study]
The author’s views are entirely his or her own (excluding the unlikely event of hypnosis) and may not always reflect the views of Moz.
Content marketing is an essential part of any SEO strategy. Without it, how are you going to attract customers looking for answers to their questions, and who are potentially in the market for your products or services?
At Tao Digital Marketing, we’ve recently generated some great results for one of our clients operating in the business financial space, The Insolvency Experts, mainly by focusing on just one “cluster topic” that was a huge money maker for them.
When looking at six month comparison stats (August 2021-January 2022 to February-July 2022), we’ve achieved the following:
Leads: 95 to 460 (384%)
Clicks: 4,503 to 23,013 (411%)
Impressions: 856,683 to 2,033,355 (137%)
Average position: 33.4 to 23.6 (increased almost 10 spots)
This was mostly achieved by absolutely hammering one topic area: company liquidation. In this case study, we’re going to explain how we did this step by step, so that hopefully you can generate similar results for your own business!
If you really break it down, the objective of all SEO consultancy work is essentially the same: increase the number of leads for a business. This was our ultimate goal.
It’s not just as simple as that, though. We all know you can’t get to number one on Google overnight. So, like other SEO geeks out there, we tracked our successes through additional factors such as clicks, impressions, and average position, to show our efforts were worthwhile.
In January this year (2022) our goals for the next six months were as follows:
Leads: Just over double from 95 to 200 (110%)
Clicks: 4,503 to 13,500 (around 200%)
Impressions: 856,683 to 1,700,000 (around 100%)
Average position: 33.4 to 25 (around eight spots)
Insolvency Experts’ audience is primarily directors of UK businesses that are going insolvent, closely followed by business owners looking for financial advice. The majority of Insolvency Expert’s cash flow comes from formal insolvency processes, such as liquidation, administration, and CVAs (Company Voluntary Agreements), so it was really important for us to push these areas.
1. Research “company liquidation” search volume and related queries
We first picked this client up in November 2020. Initially, our focus was on the basics: updating all the top level pages (such as service pages and guides) to make sure they fit the intention of the user and clearly explained the services that Insolvency Experts offer.
Researching what works well at present
One of the pages that our content team updated was their company liquidation guide. After updating, the page started to perform very well in the SERP, and ranked at position #4 for “company liquidation”. Clearly, this sort of content was working, and we wanted to hit it even more.
After pulling some research together, one of our strategists proposed the idea of a “Company Liquidation Content Hub”, as the company liquidation guide was ranking for a lot of long tail questions:
After cross referencing with the monthly search volume for these questions, she added some of these as H3s within the guide to see how they would perform. They resulted in so much more traffic that she decided they warranted their own individual guides, hence the idea for the hub. This would mean we weren’t putting all of our eggs into one basket, and that we could also internally link all of them together for users wanting to read more.
Users that are further down the marketing funnel don’t want to scroll down a huge guide to find the answer to their specific question, and we were certain that this would positively affect bounce rate. We therefore made sure that nine times out of 10, the H1 contained the question that was being answered.
In order to further target those at the bottom of the marketing funnel who want to speak to someone quickly, we placed regular “Contact Us” CTAs throughout the content so that they don’t have to scroll right to the bottom of the page to get in touch with Insolvency Experts.
Undertaking a competitor analysis
We also conducted a competitor analysis on this topic, focusing on three key players in the industry that were all ranking well for the phrase “company liquidation”. We found that the key competitors had the following:
Competitor A – 38 indexed articles on liquidation
Competitor B – 23 indexed articles on liquidation
Competitor C – 47 indexed articles on liquidation
Insolvency Experts only had six indexed articles on liquidation at the time, so it was clear we needed to be on their level – this was an obvious content gap.
Pitching the content hub to the client
We suggested this idea to the client alongside a forecasting spreadsheet created by our founder, in order to justify the resource that was needed to push the client as high as possible in the rankings for company liquidation.
This spreadsheet broke down a huge list of keywords alongside monthly search volume, average click through rate for positions 1-10 on the SERP, domain authority of competitors who are currently ranking for these keywords, and average conversion rate on the site at the moment.
This unique formula would then allow us to explain to the client that for X amount of work, we predict we can get you to position X in X timeframe, and this would result in approximately X annual revenue. After pitching this to the client alongside infographics and current performance statistics, they told us they loved our ideas and agreed to let us go ahead.
2. Plan the content after client approval
After the client gave us the go-ahead, the next step was to plan all of this work based on search volume, and therefore priority order.
It’s easy to get lost in all the data within SEO, so it was incredibly important for us to have a solid plan and timeline for these changes. Topics were going to range from How to Liquidate a Company with No Money through to Administration vs Liquidation.
How we communicate planned works to our clients
In order to orchestrate clear communication between ourselves and our clients, we create a Traffic Light Report, which is a live Google Sheets document detailing all work to be undertaken for the current and next quarter. This is split into sections for technical SEO, content, and digital PR/link building (the three pillars of SEO).
This includes justification for each change we make, as well as a link to any live changes or documents. It also details when this will be done and if the action is with us or the client. The tasks are coloured in green for live changes, yellow for action needed, orange for in progress, red for anything on hold and clear for not started.
Here’s an example of what the content section of Insolvency Expert’s traffic light report looks like for their current quarter (July-September 2022):
Scheduling the tasks
We then scheduled these topics for our various content writers to work on using our project management software, ClickUp. Within each task we placed a link to a skeleton document consisting of H1s, H2s, and H3s, as well as a title, meta description and keywords to include.
3. Write the content while implementing technical SEO
By this time it was around April 2022, and it was time for us to fully attack the content portion of our task list. Since then, we’ve written 18 pieces of content around company liquidation, and still have quite a few left to go before we consider this area of focus complete.
Analyzing as we go along
Once we covered the big topics in the first couple of months of writing, we started to use Low Fruits to find smaller queries which are estimated at around 10 or fewer monthly searches. We’ve had a lot of success targeting lower search volume phrases, as these users seem to be more focused and lower down the sales funnel, so are more likely to be better engaged and convert better. A lot of the time they are pleased that you have answered their very niche question!
The below is a screenshot from a keyword analysis. We trawled through hundreds of keywords to pull out the ones relevant to the client.
We then used Low Fruit’s Keyword Extraction and SERP Analysis tool to give us further details on a select few key terms.
These terms are shown as having a search volume of either 10, less than 10 or 0. Of course, we know that this is still hugely important to cover, and targeting these will bring in a very niche reader who is much more likely to convert due to the nature of the long-tail queries.
Finalizing the hub
Our plan is to finalize the hub this fall, and ensure that everything is internally linked. There will also be a menu change to make the addition of the hub very clear. See screenshots below for the current hub vs. how it will be presented once all content is ready (screenshot taken from their staging site in Kinsta, our hosting platform where we make design changes so that the client can approve them before they go live).
Current ‘hub’ in the menu:
How the hub will look once all content is complete:
As part of our content process within ClickUp, we have a recurring task to check a new URL in Google Search Console two weeks after upload. This allows us to see if we have the “Google Spike of Acceptance”, which is a sharp incline of impressions/traffic indicating that the content will do well, before it falls then slowly rises again.
If we don’t see this spike, we carry out multiple checks, including: Is it an orphan page? Are there any technical errors? Is it indexed? If it is not indexed, we push the URL through Index Me Now.
If the issue is just that the piece isn’t getting picked up, we will take another look at the content to see if there is something else we can do to improve it, e.g. tweak the H1 or expand the content.
4. Build links to the relevant pages and homepage
We wanted to really hone in on generating links for our company liquidation page. The page has 36 backlinks, many of which were built through link building efforts. This was largely done by working with business site publications and creating natural anchor text that would help with certain keyword rankings.
As well as building links specifically to the company liquidation page, we also built links to the main URL in order to boost overall domain authority. This was done through answering queries through platforms such as HARO and Response Source, as well as working with the client to create relevant, time-specific thought leadership pieces. Here’s an example of a HARO request we responded to, the topic being “Recession-proofing tips for small businesses”:
Although the site’s domain authority tends to fluctuate between 30-33 depending on links lost and general algorithm updates, the links to specific pages have still resulted in an increase in rankings, detailed further below.
Results compared to objectives
Although we knew that our strategy was going to work well based on our experience with our other clients, we were very pleasantly surprised by the huge positive effect our work has made, which enabled us to smash the targets we set!
Goal: Increase from 95 to 200 (110%)
Result: Increased from 95 to 460 (384%)
As a result of creating incredibly useful, lengthy content and placing regular CTAs throughout the content, we managed to almost quadruple the amount of leads coming through to the client in the space of just six months.
In the six months before our liquidation project began, our Leads Dashboard within WhatConverts shows that Insolvency Experts had five liquidation leads via phone call and 10 leads via their contact form on a liquidation-focused page.
In the six-month period since we’ve been working on the content hub, they have had 38 liquidation leads via phone call and 52 leads via contact form on a liquidation-focused page.
Result: 660% increase in phone call leads and 420% increase in contact form leads.
Previous six months:
Goal: Increase from 4,503 to 13,500 (around 200%)
Result: Increased from 4,503 to 23,013 (411%)
By creating highly relevant content that matched the user’s search intent, we managed to almost quadruple the clicks over the space of six months, doubling our original 200% goal.
The site has received 29,400 clicks overall across the past 12 months. Below, you can see the huge spike in clicks and impressions from January onwards when we really started to focus on the liquidation content.
Goal: Increase from 856,683 to 1,700,000 (around 100%)
Result: Increased from 856,683 to 2,033,355 (137%)
Again, by creating highly relevant blogs, Google started to understand the relevancy of our content, so the number of impressions hugely increased. Along with the 137% increase above, over the past 12 months (August 2021-August 2022) the site has received 485,000 impressions for the query ‘liquidation’ alone.
The main company liquidation guide that we updated had a total of 732K impressions over the past 12 months, too, with a huge spike from February onwards, when we updated the guide.
Goal: Increase from 33.4 to 25 (around 8 spots)
Result: Increased from 33.4 to 23.6 (increased 10 spots)
This increase is due to the relevancy of our content and the amount of keywords each piece ranked for. As mentioned, the main company liquidation guide has worked incredibly well, ranking for 181 keywords, 67 of which are page one (37%). It now has the number one spot for the term “company liquidation”. See below for an example of queries the page is showing up for.
The page also shows up for six featured snippets as a result of us implementing FAQ schema.
335 clicks and 93,663 impressions have come from the FAQ rich results alone.
In the six months before we updated the guide, it pulled in around 650 clicks and 227K impressions. In the six months following, it brought in around 1,180 clicks and 382K impressions. We’ve practically doubled clicks on one single guide.
As mentioned, this particular piece of content has 36 backlinks, and actually ranks ABOVE the official UK government company liquidation guide, which has a domain authority of 93 (about 60 higher than ours). Clearly, we’re meeting the searcher’s intent and giving them what they are looking for.
In the six month period before we started work on liquidation, Insolvency Experts had an average click through rate of 0.5%. Over a six month period of us working with them, this more than doubled to 1.2%.
Another success worth noting is that 3 out of 6 of our latest articles have an average page view duration of between 9 and 10 minutes! The other half are averaging around 5 to 6 minutes, which is still very good. Clearly, users are wanting in-depth information on this topic.
The “What happens to a director of a company in liquidation?” guide, which went live in May, is now the fifth most clicked page on the site. when filtered on GSC by the term “liquidation”.
Overall, we’re extremely pleased with the results we generated, and so are Insolvency Experts — the company liquidation department is now inundated with queries and they are rushed off their feet!
