ROBOTS_MISSING_SITEMAP_DIRECTIVE
robots.txt has no Sitemap: directive
Synviber can fix this automatically — no connected domain requiredWhat this check looks at
Whether robots.txt declares a Sitemap: directive, independent of whether /sitemap.xml itself is reachable.
Why AI answer engines care
A crawler that only reads robots.txt won't discover your sitemap unless it already knows its URL.
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
Low severity
Scanner message: "robots.txt does not declare a Sitemap: directive"
Add a `Sitemap: <absolute-sitemap-url>` line to robots.txt so AI crawlers that read robots.txt first can discover your sitemap without already knowing its URL.
