The recent release of Lighthouse 10 brings about big changes to Google Chrome, as it introduces several user experience improvements.
Removal of TTI
The Time To Interactive (TTI) score has been removed from Lighthouse 10, which measures how long it takes for a page to become interactive. TTI was removed due to its perceived inaccuracies and lack of correlation with user experience. The three metrics that are now used to measure user experience are Speed Index, Largest Contentful Paint (LCP), and Total Blocking Time, which are metrics that are considered more accurate.
In a statement, John Mueller from Google Search Console said, “TTI was a nice metric, but it was based on the assumption that users would start interacting with a page as soon as it became interactive. This assumption was not always accurate, and TTI did not always reflect the actual user experience.”
LCP is a metric that measures how long it takes for the largest contentful paint to load on a page. LCP is a more accurate measure of user experience because it measures the time it takes for the main content of a page to become visible to the user.
Total Blocking Time is a metric that measures the total time that a page is blocked from being interactive. Total Blocking Time is a more accurate measure of user experience because it measures the time that a user is unable to interact with a page.
Lighthouse 10 also introduces several other improvements, including:
- Improved detection of content that is not visible to the user
- Improved detection of mobile-friendly issues
Advice from Google for Effective SEO
John Mueller also offered some SEO advice during the keynote. He advised against using keyword-rich domain names, as it can make it more difficult to change the focus of the brand in the future. He also advised against using clickbait headlines, as it can damage the reputation of a website. Finally, he advised against using low-quality content, as it can lead to a decrease in website traffic.
The release of Lighthouse 10 is a major step forward for Google, as it introduces several improvements to the user experience. The removal of TTI is a welcome change, as it was a metric that was not always accurate. The addition of LCP and Total Blocking Time as metrics is also a welcome change, as they are more accurate measures of user experience.
