📋 Overview
Instant Indexing pushes your URLs directly to search engines for faster discovery. This feature is only available on the Pro, Agency, and Enterprise plans. Accounts on lower-tier plans will receive an error when attempting to activate it.
⚠️ Understanding the HTTP 400 Error
When you attempt to activate Instant Indexing on an ineligible account, the API returns:
- HTTP 400 — "Unable to activate indexing"
- is_transient: false — This confirms the error is not temporary or retriable. The account does not meet the plan requirement.
This error persists even with the pixel installed, GSC connected, and sitemap registered — plan eligibility is checked separately before activation is allowed.
✅ How to Resolve This
- Log in to your Search Atlas account.
- Navigate to the top-right corner (avatar) → Billing → Plans & Top-ups tab (Billing).
- Upgrade to the Pro, Agency, or Enterprise plan.
- Once the upgrade is confirmed, return to your OTTO project and activate Instant Indexing again.
Your existing OTTO configuration — pixel, GSC connection, and sitemaps — will be preserved after upgrading.
