To check if a website is mobile friendly now, load it at a real phone width and look for sideways scrolling, text too small to read, buttons too close to tap, menus that do not open and elements that overlap. Google’s own Mobile-Friendly Test and the Mobile Usability report in Search Console were retired in December 2023, and Google points people to Lighthouse instead. Lighthouse scores speed and a few mobile basics; it does not tap through your menu or tell you a button is hidden behind a cookie banner.
What it checks
Real phone-width rendering
Your page is loaded in Chromium at 390 pixels wide, the size of a current iPhone, and screenshotted from top to bottom so you see the same thing a visitor on a phone does.
Sideways scrolling and overflow
An element wider than the screen makes the whole page slide left and right under a thumb. The scan finds content that spills past the viewport and shows where it is.
Overlapping and hidden elements
The screenshots go through a visual review for text sitting on top of other text, buttons covered by banners or chat widgets, and content cut off at the edge.
Text size and tap targets
Body text that needs pinching to read and links packed too tightly to tap accurately are both flagged, with the page area they appear in.
Mobile menu and main button
The main call to action is checked for being visible and reachable on a phone, and navigation links are checked for leading somewhere real.
Mobile speed
Google PageSpeed scores for mobile are included, so slow loading on a phone connection shows up next to the layout problems.
How to read your results
- Start with anything marked high severity on the phone view. A covered button or a menu that will not open stops visitors outright; a slightly small font only annoys them.
- Compare the desktop and phone screenshots side by side. Problems that only appear at phone width usually come from a fixed width, a wide image or table, or a widget that ignores small screens.
- Treat the PageSpeed score as one signal, not the verdict. A fast page can still be unusable on a phone, and a slower page can work perfectly well.
What an automated check can't tell you
- The scan uses Chromium at phone size, not a physical iPhone. Bugs that only happen in Safari’s engine need a real device to confirm.
- The free scan covers your homepage. Other templates, such as product or blog pages, need a paid report or their own scan.
- It cannot log in, so pages behind an account are out of reach.

Frequently asked questions
Is Google’s Mobile-Friendly Test still available?
No. Google retired the Mobile-Friendly Test tool, its API and the Mobile Usability report in Search Console in December 2023. The old address no longer runs a test.
What replaced the Google Mobile-Friendly Test?
Google recommends Lighthouse, which is built into Chrome and powers PageSpeed Insights. It measures performance and some mobile basics. For checking whether a phone visitor can actually use the page, you need a test that renders it at phone width and looks at the result, which is what this page does.
Does mobile-friendliness still affect Google rankings?
Google indexes the mobile version of your site first, so content and links missing on mobile can cost you. More directly, visitors who cannot use a page on their phone leave, and that costs you enquiries and sales whatever your ranking.
Does PageSpeed Insights check if my site is mobile friendly?
Partly. It reports mobile speed and flags a few issues such as a missing viewport tag or small tap targets. It does not show you overlapping elements, a hidden menu or a button that does nothing.
Rather have a QA engineer test it by hand?
An automated check covers what a visitor sees on load. For logged-in flows, checkout, or a launch that has to go right, I'll test the site by hand.
- Up to 10 key pages tested by hand, not a scan
- Every flow a customer uses: forms, sign-up, checkout, booking
- Real mobile and desktop browsers
- A written report in plain language, with screenshots
- A 15-minute call to walk you through it
- 10 years of professional QA experience
Tell me about your site and I'll reply personally, usually the same day.
No payment now. I'll confirm scope and price first.
