Does it work on a phone?
Mobile-friendly test
Paste an address. We open the page on a phone-sized screen in a real Chrome and show you what a visitor on a phone runs into first. It is free and needs no account.
It checks public pages only. The report gets its own link and is kept for 30 days.
What it checks on a phone
Three things a desktop never shows, which a visitor on a phone meets in the first few seconds.
The page slides sideways
Something on the page is wider than the screen, so the whole page moves under a thumb. The report says by how many pixels, and a site that clips the overflow on purpose is not counted.
The menu button opens nothing
On a phone the whole menu hides behind one button. We tap it the way a visitor would, then again to be sure, and say it opens nothing only when nothing on the screen changed.
Something covers the main button
A chat bubble, an app banner or a sticky bar sitting on the page’s main button, so the first tap lands on the wrong thing. A cookie banner does not count: every visitor closes that first.
A picture of the phone screen
The first screen at phone size, beside the desktop one, so you can see the same page the way each of them draws it.
And everything the desktop check finds
The same report opens the page and up to four more from its menu on a desktop screen, presses the menus and tabs, and lists the code that crashes, the files that fail to load and the buttons that do nothing.
What it does not measure
Google’s old test also looked at text that is too small to read, links and buttons that sit too close together, and whether the page sets a viewport tag. This check measures none of those. It looks for what stops a visitor: a page that slides, a menu that stays shut, a button nobody can tap.
Questions
Is this Google’s Mobile-Friendly Test?
No. Google retired its Mobile-Friendly Test, and the Mobile Usability report in Search Console, in December 2023. This is a different check: it opens your page the way a phone does and looks for what stops a visitor.
Which phone does it pretend to be?
A phone-sized Chrome: a 390 × 844 screen, touch, and the user agent Chrome sends from an Android phone. Most phones’ screens round to about that size.
Does it check every page?
The phone check opens the page you give it. The rest of the check opens up to four more pages from your menu on a desktop screen and lists what breaks on those.
What does it do on my site?
On the phone it presses one thing, the menu button, the way a visitor would. The rest of the check follows links to see where they lead, and never submits a form, accepts a cookie banner, or presses anything that buys, deletes, subscribes or signs in.
Is it free?
Yes, with no account and no card. There is a daily limit shared by everybody, so on a busy day you may have to come back tomorrow.
Is my report public?
It has its own link, which only the people you give it to will know. It is hidden from search engines and deleted after 30 days.
When a customer on a phone finds one
They tap what broke and write a sentence. On a phone the form opens from the bottom of the screen, and the ticket says which browser, system and screen size it came from.
