FAQ
Can robots.txt remove indexed pages?
Not directly. Use noindex/canonical/removal workflows for deindexing.
Should I block all query URLs?
Not always. Block only low-value duplicates, not important indexable pages.
Do I need to add sitemap in robots.txt?
It is recommended for better crawler discovery.
