How your site is judged.
WHAT HAPPENS
Search engines primarily use the mobile version of your site.
WHAT THAT MEANS
If content appears on desktop but not mobile, it may as well not exist.
WHAT TO CHECK
That mobile shows the same content as desktop That navigation works That text is readable without zooming That tap targets are large enough
WHAT PEOPLE GET WRONG
Hiding content on mobile to simplify the layout.
Hidden content may not be considered.
WHAT IS SAFE TO COLLAPSE
Content in accordions that loads with the page.
WHAT IS NOT
Content removed entirely on mobile.
FOR STRUCTURED DATA
Must be present on the mobile version too.
FOR IMAGES AND ALT TEXT
Must be present on mobile.
HOW TO CHECK
View your own site on a phone and compare against desktop.
Search Console reports mobile usability problems.
WHAT TO FIX FIRST
Anything reported as a usability problem.
