Everything you need to track AI rankings

Position data, share of voice, coverage metrics, and competitor benchmarks delivered as structured JSON via a single API.

• Position tracking & share of voice - get your 1-indexed rank position and sovPct across every AI engine and prompt.
• Per-prompt breakdown with competitor hits - drill into each prompt to see your position, coverage, and details.competitorHits data.
• Configurable replicates for statistical confidence - run each prompt multiple times to get avgPos, sovPct, and coveragePct you can trust.

How AI ranking works

Position is the 1-based index of your brand in the brandsMentioned array returned by each AI engine. Position 1 means you are the first brand mentioned. If your brand is absent, position is null.

Because AI responses are non-deterministic, Sellm runs configurable replicates for each prompt. Metrics like avgPos, sovPct, and coveragePct are averaged across replicates so you get statistically confident data.

Filter by provider to see ChatGPT-specific rankings, or compare position trends across all 6 engines in a single request.

Frequently Asked Questions

What does position mean in the API response?

Position is a 1-based index indicating where your brand appears in the brandsMentioned array of the AI response. Position 1 means the AI mentioned your brand first. If your brand is not mentioned, position is null.

Why do you run multiple replicates per prompt?

AI responses are non-deterministic. Running the same prompt multiple times (replicates) gives you statistically confident metrics. avgPos, sovPct, and coveragePct are computed across all replicates so you can trust the data.

Which AI search engines does this cover?

The Rank Tracking API covers ChatGPT, Claude, Perplexity, Gemini, Grok, and Microsoft Copilot. You can filter by provider or get cross-platform rankings in a single request.

How much does it cost?

Less than $0.01 per prompt. Pricing scales with the number of prompts and replicates you run. No per-seat fees, no hidden charges.

Can I track competitor rankings alongside my own?

Yes. Configure a competitor set in your project and the API returns their avgPos, sovPct, and coveragePct alongside yours for every prompt and run via the details.competitorHits field.
