Mobile Friendly Test
Run a self-assessment of your page's mobile-friendliness: paste your HTML to check the viewport tag, then answer a few checks for a pass/fail estimate — free, fast and private.
How to use Mobile Friendly Test
- Paste your page's HTML (or just its ) into the box.
- Click Run Test to check for a viewport meta tag and other basics.
- Answer the on-page checks: readable text, tap targets and horizontal scrolling.
- Read the estimated pass/fail result and the fixes listed.
Note: this tool runs in your browser. Nothing is uploaded.
Honest note: This is a SELF-ASSESSMENT estimate based on the HTML you paste and the checks you answer. It is not Google's Mobile-Friendly Test and does not load or render your live page — browsers cannot fetch and render other sites. For an official result, use Google Search Console's Mobile Usability report.
Frequently Asked Questions
Does this test load my live website?
No. You paste your HTML and answer checks yourself. It estimates mobile-friendliness from those inputs only.
Why is the viewport meta tag important?
Without <meta name=viewport>, phones show the desktop layout zoomed out, so text is tiny and users must pinch-zoom. It is the single most common mobile failure.
What counts as a tap target problem?
Links and buttons closer than about 48 px apart, or smaller than about 48 px, are hard to tap on a phone and count against mobile-friendliness.
Is my HTML uploaded anywhere?
No. The check runs entirely in your browser.
