PageSpeed Insights With Lighthouse 11

Lighthouse 11

Lighthouse is a free, open source measurement solution that helps troubleshoot website performance problems. It is also the technology behind Page Speed insights and other core web health measurement tools. Lighthouse 11 was released by Google on August 28, 2022.

Changes To Lighthouse 11/PageSpeed Insights:

There are many changes introduced.

The following changes and additions are notable:

• New accessibility audits
• Improvements to best practices scoring
• Fixed largest contentful paint scoring bug
• Updated interface to next paint (INP) as it is no longer experimental Various bug fixes
  
  

Interaction to Next Paint (INP):

INP is a metric that looks at how well a webpage is interacting with other pages on the same page. It used to be an experimental metric, but Google dropped it from the testing phase in May. It's expected to be a Core Web Vital metric in 2024.

Lighthouse 11 has been updated to reflect the fact that INP isn't experimental anymore.

This text is about fixing a bug that was causing a big problem with the largest content score (LCP) score.

The LCP diagnostic showed an error in the scoring, which was a bug that came with Lighthouse 10.0.

Lighthouse 11 introduces thirteen new accessibility audits:

1. aria-allowed-role
2. aria-dialog-name
3. aria-text
4. html-xml-lang-mismatch
5. image-redundant-alt
6. input-button-name
7. label-content-name-mismatch
8. link-in-text-block
9. select-name
10. skip-link
11. table–duplicate-name
12. table-fake-caption
13. td-has-header

Aria-Allowed-Role

Basically, it's a set of tags that make it easier for people who use assistive tech to use the website.

Image-Redundant-Alt

This audit is used to figure out if there's any other text that's redundant because it's next to something that says the exact same thing.
