Questions people ask
Does Google still have a Mobile-Friendly Test?
Google retired its own tool in December 2023 and points people to Lighthouse. This test checks the page's mobile setup, and the free site audit runs Lighthouse on mobile.
Why does mobile matter for SEO?
Google indexes the mobile version of your site first, so what phones see is what gets ranked.
