robots.txt is missing
Synviber can fix this automatically — no connected domain requiredWhat this check looks at
Whether /robots.txt exists at the site root.
Why AI answer engines care
Without a robots.txt, AI crawlers have no explicit machine-readable signal that they're allowed to access public content.
Does Synviber fix it for me?
Yes. Synviber's GEO scan can generate and publish a fix for this without a connected domain — it writes the suggestion to your Knowledge Hub, or publishes it live immediately if the domain is connected.
How to fix it manually
