Engine chips: what green, grey and red mean

The chips

Under the visibility score is the engine coverage strip: one chip per engine: ChatGPT, Gemini, Claude, Perplexity and Grok. An engine that is not configured on the platform shows a dashed Not configured note instead of a chip: it is not measured, so it is absent from the score, the mention rate and the ± range, never counted as a 0.

• Green — the engine answered and the answer was scored.
• Grey — the engine did not contribute to this check. Either it returned an error, or its answer was cut off before it reached the point of naming anyone. A cut-off answer is inconclusive, so it is not counted, neither as a miss nor as a mention.
• Red — the engine has been failing consistently over the recent window.

A tooltip on each chip gives the reason and the model that answered.

A failed answer is never "not named"

When an engine's newest answer to a question failed, that engine's last good answer stands in for it: the question shows that answer with its own date and says the newest attempt failed, with a short reason such as "HTTP 429", "timed out" or "out of credit". The score uses the stand-in while it is less than 90 days old. An engine that has never answered a question shows the error and is left out. In no case is a failure counted as a miss, in the score, the "N of M answers" counts or an email.

"Dark weight"

When engines are missing, the score is computed over the ones that answered, and the dashboard shows what share of the engine weighting was dark. A score built from two engines is still a score, but it is a narrower one, and its range is wider to match.

What to do

Nothing — a dark engine is our problem, not yours, and engine health is monitored daily. If an engine stays grey for more than a week, the support team already has an alert for it; you can also mention it in a support message and we will confirm the cause.

Why the chip can say "read 3×, not named"

An engine can cite a page on your site as a source and still not name your brand in the answer. The chip reports both: it was read, and it was not named. That gap is common and is one of the first things the improvement plan works on.
