Ad Coverage

Advertising is not equally present across every AI response. Some prompts generate sponsored content, while others remain entirely organic. Ad Coverage measures how much of your tracked AI search landscape contains advertising, making it the primary indicator of how monetized your prompt territory is. Rather than measuring a specific advertiser’s performance, Ad Coverage looks at the market itself: how frequently ads appear across all observed results.

​

How Ad Coverage is calculated

Ad Coverage represents the proportion of results containing at least one ad within the current analysis. The calculation is:

Ad Coverage = Results containing at least one ad ÷ Total results

The metric is expressed as a percentage (%). The denominator always corresponds to the current analysis scope. If you apply filters such as engines, date ranges, themes or topics, the total number of results is recalculated accordingly and Ad Coverage is updated automatically.

Example If your filtered analysis contains 200 results and 40 of them contain at least one ad, Ad Coverage is 20%.

How to read this KPI

A higher Ad Coverage means advertising appears across a larger proportion of the AI results you track. It measures advertising prevalence, not advertising volume. A result containing one ad and a result containing several ads both count as results containing advertising. Ad Coverage is therefore useful for comparing how monetized different engines, periods or parts of your prompt territory are.

​

How this KPI fits with other signals

Ad Coverage complements:

• Unique Advertisers — shows how many advertiser domains participate in the advertising landscape.
• Ad Presence Rate — measures how broadly a specific advertiser appears across ad-supported prompts.
• Share of Ad Voice — measures how much of the observed paid visibility an advertiser captures.

Together, these signals help distinguish between how much advertising exists, how many advertisers participate, and who captures that visibility.
