Is Google's Mobile-Friendly Test still available?
No. Google retired its Mobile-Friendly Test and Search Console's Mobile Usability report on December 1, 2023. Mobilify It is an independent alternative for a first technical review: it combines public-page HTML checks with Lighthouse mobile diagnostics when available, rather than reproducing Google's former pass/fail verdict.
How to test if a website is mobile friendly
Paste your website address above. We fetch its public homepage and sample up to four reachable internal pages for technical signals. Your overall A–F grade combines homepage HTML checks with available Lighthouse performance, accessibility, and SEO scores. The test does not change your website or replace a real-device review.
What to do if your site fails
Common fixes include adding a viewport tag, compressing images, enlarging buttons and simplifying navigation. If you'd rather not do it yourself, UpCode Studios can rebuild your site to be fully mobile responsive — request a free estimate.
Five pillars of a mobile-friendly website
A responsive website needs more than a layout that shrinks. Use the audit to find technical warning signs, then check these essentials on real devices.
1. A layout that reflows
Use a device-width viewport and flexible grids. Check portrait and landscape views on phones and tablets: menus, tables, and forms should fit without horizontal scrolling. Our HTML checks flag clues, not proof of a correct rendered layout.
2. Controls you can tap
Give buttons and links enough space to avoid accidental taps. WCAG 2.2's minimum target-size criterion is 24 × 24 CSS pixels, with exceptions; larger controls often improve comfort. This audit detects contact links and forms, but does not measure button dimensions or spacing.
3. Readable, accessible content
Keep text readable without zooming, use clear headings, and label form fields. Check keyboard focus and screen-reader behavior too. Automated HTML and Lighthouse checks can reveal common barriers, but cannot certify accessibility compliance.
4. Images that fit the screen
Use responsive image sizes, compress large files, and reserve image space to reduce layout movement. The audit looks for image-format, loading, and sizing clues in HTML. It does not measure the total size of every downloaded asset.
5. Fast, stable loading
When available, Google Lighthouse provides a simulated mobile performance test. Look at Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS), then use First Contentful Paint (FCP) and Total Blocking Time (TBT) to investigate loading and script problems.
Mobilify It, PageSpeed Insights, or a manual review?
These checks answer different questions. Combine them rather than relying on a single pass/fail score.
| Approach | What it tells you | What it cannot establish |
|---|---|---|
| Mobilify It free audit | Homepage and sampled-page HTML signals, plus homepage mobile Lighthouse scores when available. | Full-site coverage, rendered tap-target measurements, real-user INP, or accessibility certification. |
| Google PageSpeed Insights | Lighthouse lab diagnostics and real-user Chrome data when enough field data exists. | Whether every page, booking flow, and design works for your customers. |
| Real-device and manual review | Actual navigation, forms, content reflow, zoom, and assistive-technology behavior. | A universal verdict from one device or one tester; test representative pages and tasks. |
Understand Core Web Vitals before interpreting a score
Good real-user Core Web Vitals are LCP at or below 2.5 seconds, INP at or below 200 milliseconds, and CLS at or below 0.1, assessed at the 75th percentile of visits. This tool reports Lighthouse lab diagnostics, not that real-user assessment. Results can vary between runs, and Lighthouse may be unavailable for pages that block access or when the external service cannot complete a test.

Is Google's Mobile-Friendly Test still available?
No. Google retired the Mobile-Friendly Test and Search Console's Mobile Usability report on December 1, 2023. Lighthouse remains useful for performance and accessibility diagnostics. Mobilify It is an independent audit, not Google's former pass/fail test.
What does this free mobile-friendly test check?
It fetches public HTML from your homepage and up to four reachable same-site pages. It checks mobile viewport settings, responsive styling clues, fixed-width patterns, image markup, form labels, headings, metadata, and other technical signals. When PageSpeed Insights is available, the report also includes homepage Lighthouse mobile scores.
Does this test measure all Core Web Vitals?
No. The Lighthouse report includes lab LCP and CLS, plus FCP and TBT diagnostics. It does not report Interaction to Next Paint (INP) or real-user field data. Check PageSpeed Insights or Search Console for available field data; FCP and TBT are not Core Web Vitals.
What is a good mobile performance score?
Lighthouse considers 90–100 a good category score, 50–89 needs improvement, and 0–49 poor. Mobilify It's overall A–F grade is a separate score combining HTML checks and available Lighthouse results. A high score does not guarantee a good design or higher search rankings.
Can a website pass automated checks and still be hard to use?
Yes. A viewport tag or responsive stylesheet does not prove that a menu, form, or checkout works on a real phone. Test key tasks on real devices, with zoom and keyboard navigation, before treating a report as a complete review.
Will running the audit change my website?
No. The test reads public pages and reports findings; it does not edit, publish, or automatically convert your site. You can request a free custom responsive redesign estimate from UpCode Studios after reviewing the results.
