Search Atlas uses three separate resource systems that are commonly confused. OTTO Site slots, Hyperdrive Credits (HDC), and AI quotas are each independent — exhausting one does not draw from another, and adding a site to one tool does not automatically activate another.
🏗️ OTTO Sites: Slot-Based Quota
Your plan includes a fixed number of OTTO Site slots. Activating OTTO SEO (Left sidebar → OTTO SEO → All Sites) on a domain consumes one slot. Deactivating OTTO on that domain returns the slot to your plan allowance.
- Adding a site to Site Auditor, Keyword Tracker, or Site Explorer does not consume an OTTO Site slot — these tools have their own separate project limits.
- Users on older plans may see two distinct quota lines: OTTO V1 Projects and OTTO V2 Projects. Both are tracked independently.
💳 Hyperdrive Credits (HDC): Spendable Balance
Hyperdrive Credits are a spendable balance used for specific paid services:
- LinkLab orders
- Press Release distribution
- Cloud Stack content generation
- Authority Building campaigns
- URL Indexer top-ups
HDC does not cover AI suggestion generation or AI content generation — those draw from a separate AI quota pool. Your plan includes an HDC allocation; if it runs out, it does not reset automatically. You must purchase additional credits to continue using HDC-powered services.
🤖 AI Quotas: Three Independent Limits
AI-powered features draw from three separate quota pools, each with its own limit:
- AI Suggestions — Covers OTTO-generated on-page recommendations
- AI Premium — Higher-quality content generation, used by tools such as Content Genius
- AI Content — Standard AI content generation volume
When your AI Suggestions quota is exhausted, OTTO stops generating new recommendations without always displaying an in-app alert. Check your quota usage proactively to avoid unexpected interruptions.
🔍 How to Check Your Quotas
- Log in to your Search Atlas dashboard.
- Click your Avatar (top-right) → Billing → Plans & Top-ups.
- Review each section separately: OTTO Sites, Hyperdrive Credits, and AI quotas are displayed as distinct quota lines, not a single combined balance.
