Mobile-Friendly Test
iWebSeoTool Mobile-Friendly Test: Enter a URL to run a free mobile-friendly test that checks its status, viewport tag and responsive signals.
Enter a page URL. This is a basic check: our server fetches the page once with a mobile user-agent and checks its status, viewport tag and responsive signals. It is not Google's official mobile test and it does not render the page on a real phone.
How to use it
- Paste the full URL of the page you want to check, including https://.
- Run the test and wait for the result to load.
- Review the status, viewport and responsive signals, then fix anything marked as missing.
About this tool
This mobile friendly checker is a simple way to run a mobile seo test before you open a page on a phone. It fetches the page with a mobile user-agent and reports whether the page responds, whether a viewport tag is present, and whether it carries responsive signals such as width=device-width. That viewport checker result is a useful first pass: a missing viewport tag is one of the most common reasons a page looks squeezed on a small screen.
Please note what this tool is and is not. It is a basic server-fetch check only — not Google’s official test, not a rendered-phone test, and it gives no Google score. It does not open the page like a browser, so layout, tap targets and real-device display still need a phone check. For a fuller picture, you can also try the Website Speed Checker, the Mobile-First Index Tool and the Word Counter from iWeb Seo Tool.

A mobile-friendly page is one that visitors can read and use comfortably on a phone. Its text is readable without zooming, its content fits the screen width, and its links and buttons are easy to tap.
