Lighthouse 10 Improves PageSpeed Scores For 90% Of Web Pages

Experienced marketers should not be too unfamiliar with Google Lighthouse. Google has recently announced Lighthouse 10 with a new big change: a change in scoring with the removal of the Time To Interactive (TTI) score.

Tests conducted on over 13 million web pages indicate that 90% of web pages will see improved scores and that 50% of webpages will see performance improvements of over 5 points.

Good news for marketers and SEO agencies, isn’t it?

Scoring Change

Google has recently announced and released Lighthouse 10, and according to its developer blog, it has removed the Time To Interactive (TTI) score. TTI’s 10% score weight is shifting to Cumulative Layout Shift (CLS), which will now account for 25% of the overall performance score. This will improve most pages’ performance scores since most pages tend to score better on CLS than TTI.

New Audits

Other than a change in scoring, Lighthouse 10 also brings a brand new performance audit. The back/forward cache (bfcache) is one of the most powerful tools available for improving a page’s performance for real users. Beyond the normal browser cache, a page loaded from the bfcache will restore page layout and execution state nearly instantly, largely skipping all page load activity and getting your page in front of your users immediately as they navigate backward and forward through their history.

Lighthouse 10 is available immediately on the command line through npm and in Chrome Canary. It will land in Chrome stable in Chrome 112 and in PageSpeed Insights soon.

What is Lighthouse?

Lighthouse is an open-source, automated tool for improving the quality of web pages. You can run it against any web page, public or requiring authentication. It runs audits for Performance, Accessibility, Progressive web apps, SEO, Best Practices, and more.
