How does your page look on a phone?
Paste the page your ads send people to. We open it on a phone-sized screen and list what sits on the first screen, the one a visitor from an ad judges before deciding whether to scroll.

We open your page in a phone-sized browser, 375 by 812 pixels, as a first-time visitor. If a cookie banner covers the page, we hide it without accepting or rejecting anything. If an offer pop-up opens on load, we note its headline and button, then close it the way a visitor would. Then we read the first screen in the order a visitor does: the main heading, the text, and the buttons and links that lead somewhere, and whether the main heading made it onto that screen at all. A real phone's browser bars take up part of the screen, so a visitor sees a little less than we do: treat anything near the bottom as borderline. We also check that the page has a phone viewport tag, and ask Google PageSpeed Insights how much the layout jumps while it loads. If the phone pass couldn't run, every line says "not measured".
| Check | How we measure it |
|---|---|
| What sits on the first screen, in reading order | A phone-sized browser, 375 by 812 pixels |
| Whether the main heading is on the first screen or below it | The same phone pass |
| An offer pop-up that opens on load, and what it says | The same phone pass |
| Phone viewport tag | The page's own code |
| How much the layout jumps while loading | Google PageSpeed Insights, phone lab test |
No. Google retired the Mobile-Friendly Test, its API and the Search Console Mobile Usability report in December 2023, and now points people to Lighthouse, which is built into Chrome.
A list, in reading order, of what sits on the first screen: the main heading, the text, the buttons and links. It says whether the main heading is on that screen or below it, and names any offer pop-up that opens on load.
375 by 812 pixels, the screen size of iPhones like the 13 mini. Bigger phones show a little more, and every phone's browser bars take a little away.
Your phone may be logged in, may have accepted the cookie banner already, may show a saved copy of the page, or may be a different size. We see the page the way a first-time visitor does.
A visitor from an ad hasn't chosen your business yet; they tapped an ad. The first screen is what they judge before deciding whether to scroll. If the thing you want them to do isn't on it, they have to go looking.
Google's search guidance discourages pop-ups that cover the main content on mobile, because they make the page harder to use. We tell you whether one opens on load and what it says.
How much the page jumps while it loads, measured by Google as Cumulative Layout Shift. Google counts 0.1 or less as good and more than 0.25 as poor. A jump just as someone taps is how people press the wrong thing.
No, we never submit your form. We don't log in or create accounts either, and the ad tracking on your page is stopped inside our browser, so our check isn't counted as a lead in your ad accounts.
