Indexing
Engines & coverage
Which search engines the indexing service supports, how each ingests URLs, and the per-country coverage map.
The service groups engines into automation tiers. One IndexNow key already fans a change out to most engines; the direct Bing/Yandex/Google/Baidu modules add deeper control (quotas, sitemaps, onboarding).
Automation tiers

|---|---|---|
| IndexNow (one key, ≤10k URLs/req) | Bing, Yandex, Naver, Seznam, Yep (Ahrefs) | POST to api.indexnow.org, bing.com, yandex.com. Google does not support IndexNow. |
| GSC Sitemap API for all pages + Indexing API (200/day, JobPosting/BroadcastEvent only) for time-sensitive pages. Service-account JSON; the SA must be a GSC owner. | ||
