Často kladené otázky
Základní odpovědi na technické otázky hodnocení a indexace.
What makes a page non-indexable?
Common causes include noindex (meta or X-Robots-Tag), soft/hard blocks, error statuses, or a canonical pointing to a different URL.
Should every page have a canonical tag?
Self-referencing canonicals are recommended—especially for parameterized, paginated, or near-duplicate URLs.
What is X-Robots-Tag?
An HTTP header that can set robots directives (like noindex) without an HTML meta robots tag. This tool reports it when present.
Does robots.txt alone remove a page from Google?
No. robots.txt controls crawling. Use noindex (and indexing tools) when you need a URL kept out of the index.
Can wrong canonicals hurt SEO?
Yes. They can consolidate signals to the wrong URL or hide important pages from the index.
Is the indexability score from Google?
No. It is a deterministic Zetawala score from fetched headers and HTML signals—not an official Google metric.
