llms.txt covers 472/700 sitemap doc pages (67%); 228 missing; 6 nested indexes omitted (251 sitemap pages excluded); 58 llms.txt links not in sitemap (may indicate stale links or incomplete sitemap)
Your llms.txt covers 67% of your site's pages (below 80% threshold). 228 live pages are missing from the index. If unintentional, regenerate llms.txt from your sitemap or build pipeline. If intentional, lower the threshold or set it to 0 to make the check informational.

Sitemap lists the docs pages
The sitemap at https://developers.webflow.com/sitemap.xml lists 81 of the 101 docs pages found through llms.txt and page links.
Generate the sitemap from the same source as the docs, so every page is listed. Agents and crawlers use it to find pages that navigation does not link.
Check your fix:
curl -s https://developers.webflow.com/robots.txt | grep -i sitemapnames a sitemap, and that sitemap lists the pages the report names as missing.Crawlers and AI assistants may read the docs
robots.txt lets Googlebot, Bingbot, OAI-SearchBot, PerplexityBot, Claude-SearchBot and Claude-User read the docs.
Freshness
Maintenance2 passed1 failed
Pages say when they were last changed
0 of 15 sampled pages state when they were last changed, and 14 more have a date only in the sitemap.
Publish a last-modified date on every page: as article:modified_time or dateModified in the page, a visible "Last updated" line, or a Last-Modified header. Agents can then tell how current a page is; the date itself is not judged.
Check your fix:
curl -sI https://developers.webflow.com/apps/data/docs/app-metrics | grep -i last-modifiedreturns a date, or the page carriesarticle:modified_timeor a visible "Last updated" line.Links and section anchors work
All 33 links and 3 section anchors checked on the sampled pages work. 8 more could not be verified (timeouts or blocked requests) and are not counted.
Sitemap entries still exist
All 10 sitemap entries sampled still exist.
Consistency with the API specNot applicable
Endpoints in the docs exist in the API spec
No OpenAPI description was found, so the docs could not be compared with a spec.
CurrencyNot applicable
Deprecated operations are marked as such
No OpenAPI description was found, so deprecation notices could not be compared with a spec.
Additional checks
Not part of the score: optional extras that help agents use your docs.
MCP server is discoverable
An MCP server answers at https://mcp.webflow.com/mcp; agents need to sign in to use it.
llms-full.txt is available
llms-full.txt found at https://developers.webflow.com/llms.txt (6,611 characters).
Agent skills are published
No agent skills index was found at /.well-known/agent-skills/index.json.
Publish an Agent Skills index at /.well-known/agent-skills/index.json with a SKILL.md for your main tasks, so agents can load task instructions without reading every page.
