What is Google Lighthouse?
Google Lighthouse is a free, open-source tool from Google that helps improve website quality, speed and performance.
It can be used to test any webpage, whether public or needing a login. Lighthouse runs audits and then generates a report on the page's overall performance.
The report highlights failing audits to show areas that need work. Things like:
Page speed
Mobile-friendliness
Accessibility
So web developers, SEOs and site owners can use Lighthouse to identify issues hampering their site's user experience, visibility, and traction. Fixing these helps websites better serve and retain visitors.
