What makes a measurement verifiable?

50 questions15 engines17 surfaces Get your free AI visibility check

A measurement is verifiable when its query set, surfaces, repeat count and measurement dates are published, so the same conditions can be run again and the result checked by someone else.

This is the sense CiteAngle uses when it measures. The word travels with other meanings in this market, so we pin ours before it turns up in a report.

Where this lands in the measurement

A number built from conditions nobody can see cannot be checked, and a number nobody can check is a weak thing to sign a contract on.

So the report carries the conditions alongside the result.

What it costs to leave this loose

A number built from conditions nobody can see cannot be checked by anyone, including you. That is a weak thing to sign against.

The query set, the surfaces, the repeat count and the dates are published with the result, so the same conditions can be run again by someone else.

Who you want measuring this

One reading does not settle a term like this. The answer an assistant writes today can name different companies tomorrow, so a Panorama round puts 50 buyer questions to every place on our US list, 7 separate times each, and reads all 17 of them — ChatGPT · Perplexity · Claude · Gemini · Grok · Google AI Overviews · Google AI Mode · Bing Copilot · DuckDuckGo AI Assist · Google Search · Bing Search · Yahoo Search · DuckDuckGo Search · Google News · Bing News · YouTube · Google Short Videos. Radar starts at 5 questions and covers the same list under the same rule.

That is why we count 2 more surfaces than the places we ask.
Where we ask, set beside the surfaces we count. One place can be asked once and still be counted in two, so the two totals differ.

We put the same questions to the competitors you name inside the same runs, so you see both in one table. The conditions are sealed, so you can reproduce the round and check it, and every planned observation is published with its state, failures included. When you choose who measures this, check that all three are in place.

That describes how the measuring is done. It is not a promise about where your numbers land.
