Why did Google shut down the Mobile-Friendly Test?

Google retired the standalone Mobile-Friendly Test in December 2023 because mobile-friendliness became a baseline expectation rather than a differentiator. Google shifted focus to Core Web Vitals (LCP, CLS, INP) and page experience as ranking signals. The mobile-friendly status is still tracked in Google Search Console under Page Experience.

Does Viewpo test the same things as Google's Mobile-Friendly Test?

Viewpo covers everything Google's tool tested — viewport configuration, text readability, content width, and tap targets — and goes further with contrast checking, image audits, accessibility checks, and multi-device screenshots. The A-F grade gives you a clear picture of how well your site works across all screen sizes, not just mobile.

Can I check mobile-friendliness in Google Search Console?

Google Search Console shows mobile usability issues under Experience > Page Experience, but it only flags pages Googlebot has already crawled. It doesn't let you test a specific URL on demand. For instant, on-demand mobile testing with screenshots and grading, use Viewpo or Lighthouse.

Google retired the Mobile-Friendly Test. Here's what replaced it.

Google shut down its Mobile-Friendly Test in December 2023. Viewpo picks up where Google left off — with real browser rendering, automated grading, and multi-device screenshots.

What to look for in a mobile friendly test

Key criteria for choosing the right tool — and how Viewpo stacks up.

Real browser rendering

Google's original Mobile-Friendly Test used Googlebot to render pages. Most replacements use iframes or emulated viewports, which miss real-world layout issues.

Viewpo renders every page in a real Chromium browser on Cloudflare's network — the same engine your visitors use.

Beyond pass/fail

Google's tool gave a binary "mobile-friendly" or "not mobile-friendly" result with minimal detail. Modern responsive design needs more nuance.

Viewpo grades from A to F and explains every issue — overflow, touch targets, contrast, images, and accessibility.

Multiple device sizes

The original Google tool only tested at a single mobile viewport. Real users browse on phones, tablets, laptops, and desktops.

Viewpo tests at phone (375px), tablet (820px), laptop (1440px), and desktop (1920px) simultaneously.

Shareable proof

Google's tool had no way to share results. You couldn't send a report to a client or save it for later.

Every Viewpo audit generates a permanent, shareable URL with OG preview cards — send it to anyone.

Why Google retired the Mobile-Friendly Test

Google's Mobile-Friendly Test launched in 2014 when mobile traffic was overtaking desktop. It was a simple pass/fail check: "Is this page mobile-friendly?" By 2023, Google considered mobile-friendliness a baseline expectation and shifted focus to Core Web Vitals and page experience signals. The standalone Mobile-Friendly Test was retired in December 2023, with Google recommending Lighthouse for mobile testing. But Lighthouse wasn't designed as a drop-in replacement — it's a developer-focused performance tool, not a simple "paste URL, check mobile" experience.

What to use instead in 2026

The landscape of mobile testing tools has shifted since Google's tool went offline. Most free alternatives (responsivedesignchecker.com, responsivechecker.net) use iframes to display your site at different widths. The problem: modern sites block iframe embedding with X-Frame-Options or Content-Security-Policy headers, so these tools show blank pages or errors on half the sites you test. Viewpo takes a different approach — it renders your site in a real Chromium browser, takes actual screenshots, and runs automated checks for the issues that matter most: content overflowing the screen, touch targets too small to tap, images without alt text, and contrast that fails on smaller screens.

What the Mobile-Friendly Test checked (and what Viewpo adds)

Google's original test checked five things: viewport configuration, text size (readable without zooming), content width (fits the screen), links and tap targets (spaced enough to tap), and blocked resources (CSS/JS not blocked from Googlebot). Viewpo covers all of these and more: horizontal overflow detection catches content that doesn't fit the screen. Touch target analysis flags buttons smaller than 44x44px. Image audits catch missing alt text and oversized images. Contrast checking catches text that's unreadable on small screens. Accessibility checks catch missing landmarks, heading order issues, and unlabelled form inputs. Each issue comes with a plain-language explanation — not a cryptic error code.

Frequently Asked Questions

Common questions about choosing a mobile friendly test.

Yes. Google recommends Lighthouse (built into Chrome DevTools), but it requires developer knowledge to use. Viewpo is the closest replacement to the original experience: paste a URL, get a result. Viewpo's free tier includes 50 audits per month with real browser screenshots at 3 viewport sizes and A-F grading. No account required for basic audits.
