Is Your Page Mobile-Ready? Check the Viewport Tag
The viewport meta tag tells mobile browsers how to scale your page — without it, your site renders like a tiny desktop page on phones. Enter any URL and this free checker fetches the page and reports whether the tag exists.
If the tag is found, you see its exact content (width, initial-scale, and other settings) so you can verify it is configured correctly for responsive design.
Finds the exact tag
The checker parses the page's HTML and shows you the full viewport meta tag it found, not just a yes/no answer.
Any public URL
Test your own site or any public page — just paste the URL and get the result in seconds.
How it works
When you submit a URL, our server fetches the page's HTML and scans it for a meta viewport tag. Because the fetch happens server-side, it works for any publicly reachable page.
How to use
- Enter the full URL of the page you want to test.
- Click Check Viewport.
- See whether the viewport meta tag exists and read its exact content.
Frequently Asked Questions
What is the viewport meta tag?
It is an HTML meta tag — usually — that tells mobile browsers to render the page at the device's width instead of shrinking a desktop layout.
Why does the viewport tag matter for SEO?
Google uses mobile-first indexing, so pages without a proper viewport tag render poorly on phones and can suffer in mobile search results.
What does a correct viewport tag look like?
The standard is content="width=device-width, initial-scale=1", which makes the page match the screen width at normal zoom.
Can I check someone else's website?
Yes. Any publicly reachable URL can be tested — useful for auditing client sites or competitors.
Is the checker free?
Yes, completely free with no signup.
