Ad Presence Rate

Advertisers don’t participate equally across every prompt where advertising appears. Some advertiser domains are present across a broad range of user needs, while others concentrate their paid presence around fewer prompts. Ad Presence Rate measures how much of your ad-supported prompt territory is occupied by a given advertiser domain, making it an indicator of paid visibility breadth. Rather than counting how many ads an advertiser generates, it measures across how many ad-supported prompts the advertiser is present.

​

How Ad Presence Rate is calculated

Ad Presence Rate represents the proportion of ad-supported prompts where a given advertiser domain is present. The calculation is:

Ad Presence Rate = Ad-supported prompts where the advertiser is present ÷ Total ad-supported prompts

The metric is expressed as a percentage (%). The denominator always corresponds to the ad-supported prompts within the current analysis scope. If you apply filters such as engines, date ranges, themes or topics, the eligible prompts are recalculated accordingly.

Example If 40 prompts generated ads within your filtered analysis and an advertiser domain appears across 10 of them, its Ad Presence Rate is 25%.

​

How to read this KPI

A higher Ad Presence Rate means the advertiser is present across a larger proportion of the prompts where advertising occurs. It measures breadth of paid presence, not advertising volume. An advertiser can therefore have:

• a high Ad Presence Rate, meaning it appears across many ad-supported prompts;
• or a lower Ad Presence Rate, meaning its presence is concentrated across fewer prompts.

The advertiser is evaluated at domain level, based on the advertiser domain retrieved from the ad.

How this KPI fits with other signals

Ad Presence Rate complements:

• Share of Ad Voice — measures how much of the total paid visibility an advertiser captures.
• Total Ads — measures the raw volume of ads associated with the advertiser.
• Ads + Organic / Ads Only — qualifies whether that paid presence overlaps with organic visibility.

Together, these signals let you distinguish between broad advertiser coverage, concentrated advertising volume, and the role paid visibility plays alongside organic presence.
