Documentation sites: keep Google's index in sync with your docs
To keep Google's index in sync with a docs site (Docusaurus, Mintlify, Fern), push new and updated doc URLs through the Indexing API on every publish so Google re-crawls the latest version instead of serving a stale page. Docs are high-page-count and change often, and a stale indexed doc is a support ticket waiting to happen.
Documentation sites are weird from an SEO standpoint: high page counts, frequent updates, and traffic that's almost entirely intent-driven (developers Googling specific error messages). Every doc page is a potential landing page, and every stale version of a doc page is a support ticket waiting to happen.
The update-and-push workflow
- Merge a doc update. Your CI deploys.
- Identify which URLs changed (Docusaurus and Mintlify both expose stable URLs per page).
- Push the changed URLs through IndexerNow. A typical docs deploy might touch 1-10 URLs — well within free quota.
- For larger refactors (new SDK reference, restructured navigation), use a $9.99 pack.
Why docs-specific care matters
- Devs trust the first Google result. If you launched a new SDK version but Google still shows the old API, devs get confused and write angry tweets.
- Code samples and error messages are unique strings. Indexing them quickly captures the exact-match search traffic.
- Outdated docs in the index drive support load. Sometimes the fix is to get the new version indexed faster.
For SDK docs, audit your top 20 reference pages quarterly. Look for: missing canonical to current version, old links to deprecated endpoints, broken anchors.
Sitemap hygiene for docs
Many doc generators include search pages, draft pages, and version-tag pages in the sitemap. Strip those before submitting. A clean sitemap of 200 high-quality pages beats a noisy sitemap of 800 mostly-duplicates every time.
