Google updated Lighthouse 8.0 and one of the important changes is to change the weights of the different speed metrics. The changes are estimated to make it easier for most sites to achieve higher page speed scores. Cumulative Layout Shift scores will likely trend higher while other metrics become stricter.
Google Lighthouse 8.0
Lighthouse is a tool that helps publishers, developers and SEOs measure page speed and other metrics related to accessibility and SEO. Lighthouse powers the online PageSpeed Insights tool and is shipped as a developer tool in Chrome.
The new Lighthouse version 8.0 will ship in Chrome 93 but is available right now in PageSpeed Insights.
Changes to Google Lighthouse Tool
- Performance score has been re-weighted
- Total Blocking Time (TBT) Scoring is Stricter
- First Contentful Paint (FCP) Scoring is Stricter
- Cumulative Layout Shift (CLS) Scoring is Less Strict
How Scores Have Changed
According to Google’s FAQ, about 20% of sites will see a drop of up to five points, while 20% might not see much change.
Google estimates that approximately 60% of sites will see a positive change, from moderate to 5 points improvement or higher.
There are estimated to be more winners with Lighthouse 8.0 that score higher than sites that score less well.
“~20% of sites may see a drop of up to 5 points, though likely less
~20% of sites will see little detectable change
~30% of sites should see a moderate improvement of a few points
~30% could see a significant improvement of 5 points or more
The biggest drops in scores are due to TBT scoring becoming stricter and the metric’s slightly higher weight. The biggest improvements in scores are also due to TBT changes in the long tail and the windowing of CLS, and both metrics’ higher weights.”
The Total Blocking Time metric is described as being stricter and could have been even more strict. But the engineers decided to dial it back so as to not be too “jarring.”
According to the TBT GitHub page:
“But we think these as our control points would be too jarring and aggressive for now. Still, there’s room to improve, so we’re doing a small shift of TBT being scored more strictly.”
Before and After Lighthouse Scores
Google published a Lighthouse Scoring Calculator showing what the differences are between versions 8.0, 6 and 7 and version 5.
Below are screenshots comparing the exact same Lighthouse scores between the different versions (6/7 and 8.0).
In the example below it shows that version 8.0 results in a lower score.
Below are a comparison of the same Lighthouse scores between versions showing a four point drop between versions 8.0 and 6/7.

Lighthouse API Update
Google published a note about changes to the API:
“The new Cumulative Layout Shift definition is now the default metric surfaced as cumulative_layout_shift, the previous Cumulative Layout Shift metric will be available for a limited time as it is phased out as experimental_uncapped_cumulative_layout_shift.
Largest Contentful Paint has undergone adjustments in recent Chrome versions and has been updated similarly in CrUX.
First Contentful Paint tri-binning thresholds have been updated to be: [0-1.8s], (1.8s-3s), [3s-∞].”

How to Write For Google
Are you writing your SEO content based on the latest best practice tips?
I originally wrote this SEO copywriting checklist in 2012—my, how things have changed. Today, Google stresses quality content even more than before, conversational copy is critical, and there are revised SEO writing “rules.”
I’ve updated the list to reflect these changes and to provide additional information.
As a side note, I would argue that there’s no such thing as “writing for Google.” Yes, there are certain things you should do to make the Google gods happy. However, your most important goal should be writing clear, compelling, standout copy that tells a story.
I’m keeping the old headline in the hopes that I can convert some of the “write for Google” people to do things the right way.
Items to review before you start your SEO writing project
– Do you have enough information about your target reader?
Your copy will pack a powerful one-two punch if your content is laser-focused on your target reader. Ask your client or supervisor for a customer/reader persona document outlining your target readers’ specific characteristics. If the client doesn’t have a customer persona document, be prepared to spend an hour or more asking detailed questions.
Here’s more information on customer personas.
– Writing a sales page? Did you interview the client?
It’s essential to interview new clients and to learn more about their company, USP, and competition. Don’t forget to ask about industry buzzwords that should appear in the content.
Not sure what questions to ask to get the copywriting ball rolling? Here’s a list of 56 questions you can start with today.
– Writing a blog post? Get topic ideas from smart sources
When you’re blogging, it’s tempting to write about whatever strikes your fancy. The challenge is, what interests you may not interest your readers. If you want to make sure you’re writing must-read content, sites like Quora, LinkedIn, Google Trends, and BuzzSumo can help spark some ideas.
– Did you use Google for competitive intelligence ideas?
Check out the sites positioning in the top-10 and look for common characteristics. How long are competing articles? Do the articles link out to authoritative sources? Are there videos or infographics? Do the articles include quotes from industry experts? Your job is to write an essay that’s better than what’s already appearing in the top-10 — so let the competition be your guide.
– Did you conduct keyphrase research?
Yes, keyphrase research (and content optimization) is still a crucial SEO step. If you don’t give Google some keyphrase “cues,” your page probably won’t position the way you want.
Use a keyphrase research tool and find possible keyphrases for your page or post. As a hint: if you are tightly focusing on a topic, long-tail keyphrases are your best bet. Here’s more information about why long-tail keyphrases are so important.
If you are researching B2B keyphrases, know that the “traditional” keyphrase research steps may not apply. Here’s more information about what to do if B2B keyphrase research doesn’t work.
– What is your per-page keyphrase focus?
Writers are no longer forced to include the exact-match keyphrase over and over again. (Hurray!) Today, we can focus on a keyphrase theme that matches the search intent and weave in multiple related keyphrases.
– Did you expand your keyphrase research to include synonyms and close variants?
Don’t be afraid to include keyphrase synonyms and close variants on your page. Doing so opens up your positioning opportunities, makes your copy better, and is much easier to write!
Are you wondering if you should include your keyphrases as you write the copy — or edit them in later? It’s up to you! Here are the pros and cons of both processes.
— Do your keyphrases match the search intent?
Remember that Google is “the decider” when it comes to search intent. If you’re writing a sales page — and your desired keyphrase pulls up informational blog posts in Google – your sales page probably won’t position.
— Writing a blog post? Does your Title/headline work for SEO, social, and your readers?
Yes, you want your headline to be compelling, but you also want it to be keyphrase rich. Always include your main page keyphrase (or a close variant) in your Title and work in other keyphrases if they “fit.”
– Did you include keyphrase-rich subheadlines?
Subheadlines are an excellent way to visually break up your text, making it easy for readers to quick-scan your benefits and information. Additionally, just like with the H1 headline, adding a keyphrase to your subheadlines can (slightly) help reinforce keyphrase relevancy.
As a hint, sometimes, you can write a question-oriented subheadline and slip the keyphrase in more easily. Here’s more information about why answering questions is a powerful SEO content play.
– Is your Title “clickable” and compelling?
Remember, the search engine results page is your first opportunity for conversion. Focusing too much on what you think Google “wants” may take away your Title’s conversion power.
Consider how you can create an enticing Title that “gets the click” over the other search result listings. You have about 59 characters (with spaces) to work with, so writing tight is essential.
– Does the meta description fit the intent of the page?
Yes, writers should create a meta description for every page. Why? Because they tell the reader what the landing page is about and help increase SERP conversions. Try experimenting with different calls-to-actions at the end, such as “learn more” or “apply now.” You never know what will entice your readers to click!
– Is your content written in a conversational style?
With voice search gaining prominence, copy that’s written in a conversational style is even more critical.
Read your copy out loud and hear how it sounds. Does it flow? Or does it sound too formal? If you’re writing for a regulated industry, such as finance, legal, or healthcare, you may not be able to push the conversational envelope too much. Otherwise, write like you talk.
Here’s how to explain why conversational content is so important.
–Is your copy laser-focused on your audience?
A big mistake some writers make is creating copy that appeals to “everyone” rather than their specific target reader. Writing sales and blog pages that are laser-focused on your audience will boost your conversions and keep readers checking out your copy longer. Here’s how one company does it.
Plus, you don’t receive special “Google points” for writing long content. Even short copy can position if it fully answers the searcher’s query. Your readers don’t want to wade through 1,500 words to find something that can be explained in 300 words.
Items to review after you’ve written the page
– Did you use too many keyphrases?
Remember, there is no such thing as keyword density. If your content sounds keyphrase-heavy and stilted, reduce the keyphrase usage and focus more on your readers’ experience. Your page doesn’t receive bonus points for exact-matching your keyphrase multiple times. If your page sounds keyphrase stuffed when you read it out loud, dial back your keyphrase usage.
– Did you edit your content?
Resist the urge to upload your content as soon as you write it. Put it away and come back to it after a few hours (or even the next day.) Discover why editing your Web writing is so very important. Also, don’t think that adding typos will help your page position. They won’t.
– Is the content interesting to read?
Yes, it’s OK if your copy has a little personality. Here’s more information about working with your page’s tone and feel and how to avoid the “yawn response.” Plus, know that even FAQ pages can help with conversions — and yes, even position.
– Are your sentences and paragraphs easy to read?
Vary your sentence structure so you have a combination of longer and shorter sentences. If you find your sentences creeping over 30 or so words, edit them down and make them punchier. Your writing will have more impact if you do.
Plus, long paragraphs without much white space are hard to read off a computer monitor – and even harder to read on a smartphone. Split up your long paragraphs into shorter ones. Please.
– Are you forcing your reader onto a “dead end” page?
“Dead-end” pages (pages that don’t link out to related pages) can stop your readers dead in their tracks and hurt your conversion goals.
Want to avoid this? Read more about “dead-end” Web pages.
– Does the content provide the reader with valuable information?
Google warns against sites with “thin,” low-quality content that’s poorly written. In fact, according to Google, spelling errors are a bigger boo-boo than broken HTML. Make sure your final draft is typo-free, written well, and thoroughly answers the searcher’s query.
Want to know what Google considers quality content — directly from Google? Here are Google’s Quality Raters guidelines for more information.
– Did you use bullet points where appropriate?
If you find yourself writing a list-like sentence, use bullet points instead. Your readers will thank you, and the items will be much easier to read.
Plus, you can write your bullet points in a way that makes your benefit statements pop, front and center. Here’s how Nike does it.
– Is the primary CTA (call-to-action) clear–and is it easy to take action?
What action do you want your readers to take? Do you want them to contact you? Buy something? Sign up for your newsletter? Make sure you’re telling your reader what you want them to do, and make taking action easy. If you force people to answer multiple questions just to fill out a “contact us” form, you run the risk of people bailing out.
Here’s a list of seven CTA techniques that work.
– Do you have a secondary CTA (such as a newsletter signup or downloading a white paper?)
Do you want readers to sign up for your newsletter or learn about related products? Don’t bury your “sign up for our newsletter” button in the footer text. Instead, test different CTA locations (for instance, try including a newsletter signup link at the bottom of every blog post) and see where you get the most conversions.
– Does the page include too many choices?
It’s important to keep your reader focused on your primary and secondary CTAs. If your page lists too many choices (for example, a large, scrolling page of products), consider eliminating all “unnecessary” options that don’t support your primary call-to-action. Too many choices may force your readers into not taking any action at all.
– Did you include benefit statements?
People make purchase decisions based on what’s in it for them (yes, even your B2B buyers.) Highly specific benefit statements will help your page convert like crazy. Don’t forget to include a benefit statement in your Title (whenever possible) like “free shipping” or “sale.” Seeing this on the search results page will catch your readers’ eyes, tempting them to click the link and check out your site.
– Do you have vertical-specific testimonials?
It’s incredible how many great sales pages are testimonial-free. Testimonials are a must for any site, as they offer third-party proof that your product or service is superior. Plus, your testimonials can help you write better, more benefit-driven sales pages and fantastic comparison-review pages.
Here’s a way to make your testimonials more powerful.
And finally — the most important question:
– Does your content stand out and genuinely deserve a top position?
SEO writing is more than shoving keyphrases into the content. If you want to be rewarded by Google (and your readers), your content must stand out — not be a carbon copy of the current top-10 results. Take a hard look at your content and compare it against what’s currently positioning. Have you fully answered the searcher’s query? Did you weave in other value-added resources, such as expert quotes, links to external and internal resources (such as FAQ pages), videos, and graphics?
If so, congratulations! You’ve done your job.
