AI Visibility
AI Visibility shows you where — and how often — AI engines cite your brand when people ask them questions. Instead of guessing whether ChatGPT or Perplexity mentions you, Terradium samples real prompts and reports the answer as a trend over time.
What prompt-sampling is
Search rank is a single number for a single query at a single moment. AI answers don't work that way: the same prompt can produce different sources on different runs, and small wording changes shift who gets quoted.
So Terradium uses prompt-sampling. For a set of prompts relevant to your brand and topics, it asks the AI engines those prompts repeatedly over time and records what comes back — whether you appeared, whether you were cited as a source, and who else showed up alongside you.
Why it's a trend, not a fixed rank
Because answers vary run to run, a single sample isn't meaningful — but the rate across many samples is. AI Visibility metrics are therefore directional trends, not guaranteed placements. You'll watch a line move up and to the right as your content gets picked up more often; you won't see a brittle "position #1" that flips every refresh.
The metrics
Across your sampled prompts, Terradium reports:
- Appearance rate — the share of sampled prompts where your brand shows up at all (mentioned or cited).
- Citation share — how often you're the named source the engine links or attributes its answer to.
- Share of voice — your slice of the cited sources versus the competitors who appear for the same prompts.
- Average position — where you tend to land among the cited sources when you do appear.
Each is shown as a current value plus its trend, so you can tell whether your GEO work is compounding.
The four engines
Terradium samples the four AI surfaces that matter most:
- ChatGPT
- Perplexity
- Google AI Overviews
- Gemini
Metrics are available per engine and rolled up across all four, so you can spot where you're strong and where you have room to grow.
Sample-run quota
Sampling AI engines costs real compute, so each billing period includes a fixed quota of sample runs. A run refreshes your metrics across your prompt set; the quota resets at the start of each billing period. You can see how many runs you've used on the AI Visibility screen.
Getting cited more
To improve these numbers, publish content that's easy for engines to quote — clear, well-structured answers to real questions. The Terradium content pipeline is built to write exactly that, and Search Console tells you which questions to target.
