Frequently Asked Questions
Everything you need to know about the Mobile Friendly Test.
Why is mobile friendliness important?
Most web traffic now comes from phones, and Google uses mobile first indexing, which means it mainly looks at the mobile version of your page for ranking. A page that is hard to use on a phone loses both visitors and search visibility.
What is a viewport meta tag?
The viewport tag tells phones how to size your page. Without it, phones show a zoomed out desktop layout that people have to pinch and zoom to read. The standard tag is <meta name="viewport" content="width=device-width, initial-scale=1">.
The phone preview is blank or shows a loading image. Why?
Screenshots are generated on demand and can take up to a minute for a page that has not been captured recently. Click the refresh link under the preview after a few seconds to load the finished screenshot.
Does this tool check my external CSS files?
The tool reads your HTML, inline styles and meta tags. Responsive rules inside external stylesheets are not downloaded, so if your design uses a framework like Bootstrap or Tailwind, the phone preview is the best way to confirm the layout adapts.
