  1. Enter a public product or article page URL to check.

Try a concrete example

Check a product or article page, export its JSON snapshot and compare the results after changing the theme or SEO plugin.

How to interpret results

The checker reads initial HTML, HTTP headers and at most two representative image headers. It does not execute JavaScript. Discover recommendations include at least 1200px width and more than 300,000 pixels. Findings do not prove indexing or guarantee traffic.

Frequently asked questions

Does passing the check guarantee ranking or entry into Discover?

No. Real indexing, content policies, content quality, and Google's evaluation still require separate verification. Passing Discover technical items only indicates that current observations meet corresponding recommendations.

Why does it report image too small even when declared as 1200px?

Dimensions declared in HTML or structured data do not equal actual file dimensions; CMS themes, CDNs, or image optimization services may serve thumbnails. This tool verifies against the actual dimensions in the file header.

Why were JavaScript-generated titles missed?

This check reads initial HTML; dynamic websites can combine browser rendering and Search Console URL Inspection.

How to handle missing alt tags on images?

Informational images require concise alt text; purely decorative images can use empty alt text.
