Mobile-friendly test.
Many of your visitors are on a phone, and Google judges your site by its mobile version. Enter a page and we'll read its code for the common causes of a bad mobile experience, with a plain fix for each problem we find.
- Free, no sign-up
- We check public information only. How your data is handled
How to use the Mobile-Friendly Test
- Enter a page address. Check your home page and your key service pages.
- We read the page's HTML and its stylesheets.
- Fix the items in red first, then those in amber.
- Open the page on a real phone to confirm how it looks.
What this test can and can't tell you
This test reads a page's code. It doesn't open the page in a phone browser, so a good score means no common problems were found in the code, not that the design is proven to work. It can't judge how close together buttons are, whether content overflows the screen, or whether a pop-up gets in the way. Always finish by trying the page on a real phone.
Google retired its own Mobile-Friendly Test in December 2023. Its Lighthouse tool, in PageSpeed Insights and Chrome, can test a page in a simulated phone browser.
Why mobile matters for search
Google uses the mobile version of a site for indexing and ranking, known as mobile-first indexing. Content that's missing or broken on mobile may as well not exist. Visitors feel it too: if a page is hard to use on a phone, they go back to the results and choose someone else.
The most common fixes
- Add the viewport tag to every page: <meta name="viewport" content="width=device-width, initial-scale=1">.
- Replace fixed pixel widths with max-width: 100% or percentages.
- Use at least 16 px for body text.
- Make phone numbers tappable with tel: links, and give buttons plenty of room.
- Serve smaller images to phones using srcset. Our image resizer makes the sizes, and the website speed test shows how fast the page responds.
About the Mobile-Friendly Test.
Is this the same as Google's Mobile-Friendly Test?
No. Google retired that tool in December 2023. This is our own check of a page's code, based on the same kinds of problems. It doesn't use Google or represent how Google rates a page.
Does a high score mean my site is mobile friendly?
It means we found no common problems in the code. Layout problems only show when a page is displayed, so test on a real phone as well.
Does mobile-friendliness affect rankings?
Google indexes the mobile version of your site, so problems on mobile can hurt. A good mobile page helps, but it won't rank by itself.
What is a viewport tag?
A line in the page's head that tells phones to fit the page to the screen width. Without it, phones show a tiny desktop page.
My page looks fine but scored low. Why?
Some items, such as a missing tap-to-call link, are suggestions rather than faults. If it works well for your visitors and the reason doesn't apply to you, you can safely ignore it.
