SEO guidance

Metadata should describe the actual page and its search intent. Length recommendations are working ranges, not guarantees of how Google will display your title or description. Search engines can rewrite snippets.

Frequently asked questions

Does this tool check the live page?

Yes. GIMSEO fetches the public URL and analyzes the HTML returned by the server.

Does a good score guarantee rankings?

No. Metadata is only one part of SEO. Rankings also depend on content quality, search intent, links, crawlability, site architecture, performance and many other signals.

Can I check Open Graph and Twitter metadata?

Yes. The report displays detected Open Graph and Twitter/X Card values and provides a visual social-card preview when an image is available.
