TECHNICAL SEO
Mobile SEO Checker
Google indexes the mobile version of a page. When a theme hides content, links or structured data on phones, or a mobile site serves a different canonical, those things are missing for search. This checker fetches the page both ways and compares them.

HOW IT WORKS
How to use the Mobile SEO Checker
One public page URL.
Enter a page URL.
Check the viewport, then every difference flagged.
Make the mobile version carry everything the desktop one does.
WHAT IT CHECKS
What it looks at, and how to read it.
Viewport checks, differences between the two versions, and a side-by-side table.
What it checks
- Viewport meta tag and zoom
- Status, title, canonical and robots on each version
- Text and internal links missing on phones
- Structured data missing on phones
- Separate mobile hosts and dynamic serving
How to read the results
- Content in tabs or accordions counts; content removed from the mobile HTML does not.

GOOD TO KNOW
Common mistakes, an example and the limits.
Common mistakes
- A mobile menu with a handful of links replacing a footer of category links.
A worked example
The phone version of a product page drops the reviews block and its AggregateRating markup.
Limitations
- Checks the HTML the server sends. Content a page adds with JavaScript after loading is not seen.
- Some sites block or challenge automated requests; then the result shows what a crawler without a browser would get.
- Compares HTML, not layout: font sizes, tap targets and overflowing content need a rendering browser such as Lighthouse.
