Frequently Asked Questions

What specific on-page SEO signals does this tool check?

The tool audits title tag presence and length (50-60 characters is optimal), meta description presence and length (150-160 characters), canonical URL configuration, robots meta directives (noindex/nofollow), H1 uniqueness, and Open Graph completeness. Each check returns a pass, warning, or fail status with a specific suggestion.

Can I use SEO Checker to audit multiple pages at once?

No, the tool analyzes one URL per submission. It is designed for quick single-page validation before launch or after content updates. For multi-page audits, run separate checks per URL or use the related Meta Checker and Link Preview tools for deeper inspection.

Does the SEO score directly affect my search engine rankings?

No. The score reflects on-page health based on common best practices, not a signal from any search engine. Use it as a checklist to catch missing or misconfigured elements — a missing title tag or noindex directive can block indexing entirely, which is what the tool helps you catch.
