It’s good for society and ultimately it’s also good for the bottom line.
Lighthouse 11 introduces thirteen new accessibility audits:
aria-allowed-role
aria-dialog-name
aria-text
html-xml-lang-mismatch
image-redundant-alt
input-button-name
label-content-name-mismatch
link-in-text-block
select-name
skip-link
table–duplicate-name
table-fake-caption
td-has-header
Aria-Allowed-Role
Here are two good starting points for reading all the details:
The aria-allowed-role, in simple terms, is the name for a group of labels that helps people using assistive technologies interact with the webpage.
It’s also the technology that powers PageSpeed Insights and other tools that measure core web vitals.
Landmarks allow assistive technologies to navigate and to find content quickly.”
Image-Redundant-Alt
Lighthouse is an open source measurement tool that helps debug website performance issues.
Google released the latest version, Lighthouse 11, on Monday, August 28th.
Changes To Lighthouse 11/PageSpeed Insights
Website accessibility is not currently a ranking factor and quite likely not a quality signal.
“Largest Contentful Paint element — Error!” is appearing on all websites, including your own site (https://web.dev/).
The official announcements are spread out across multiple pages, including dozens of error reports on GitHub.
“A landmark is an abstract role for a section of content that is important enough that users will likely want to be able to navigate to the section easily and have it included in a dynamically generated summary of the page.
For example, a landmark role identifies the purpose of a semantic element.
An example of redundancy is when the alt-text of a button says “Click Here” and the same text (click here) exists beneath the button.
It appears to be a bug with the latest version of Lighthouse (Lighthouse 10.2.0) when using PageSpeed Insights.”

The Mozilla reference page for the landmark role explains:
There are many changes introduced.
It was formerly an experimental metric but in May of this year Google removed it from the experimental stage and it is in line to become an official Core Web Vital in 2024.
The change in Lighthouse 11 is to formally reflect that INP is no longer experimental.
