Definition
Brand inclusion rate is the percentage of tracked prompts for which AI-generated answers include your brand. If a brand appears in the answers to 42 out of 100 relevant prompts on ChatGPT, Perplexity, Google AI Mode and Copilot, its brand inclusion rate for that prompt set is 42%.
It answers the most basic question in GEO: when buyers ask AI systems about our category, are we in the answer at all? Many AI answers are not ranked lists, so before position or sentiment matter, a brand has to be included.
Brand inclusion rate is closely related to mention rate, and the two are sometimes used interchangeably. The useful distinction is the unit of measurement. Mention rate is counted per response: the share of all collected answers that name the brand. Brand inclusion rate is counted per prompt: the share of distinct prompts where the brand is included. Because AI answers vary from run to run, teams sample each prompt several times and set a rule for when a prompt counts as covered, for example 'mentioned in at least half of the runs that week'. That makes inclusion rate a coverage map. It shows which questions a brand owns, which it wins occasionally and which it never appears in, which is more actionable for content planning than a single blended percentage.
The number is only as good as the prompt set behind it. A useful panel mixes the intents buyers actually use: category discovery ('best payroll software for remote teams'), comparisons ('Gusto vs Rippling'), problems ('how to pay contractors in Germany'), local or regional prompts where relevant, and purchase-intent questions about pricing or setup. Prompts should be phrased the way people talk to assistants, run on each engine that matters, and kept stable over time so changes reflect AI behavior rather than a new panel. Prompt research covers how to build that set.
Inclusion alone can flatter a brand. A brand can be included as a footnote, as the expensive option or as a product to avoid. Pair it with answer position, sentiment, citation rate and competitor inclusion on the same prompts. Promptwatch's visibility score, for example, counts responses without the brand as zero and then weights the rest by prominence, so it moves with both inclusion and quality of presence.
Brand inclusion rate works well for executive reporting because it is easy to explain and easy to benchmark. Report it per engine, per topic and per market, show the competitor with the highest inclusion on the same panel, and list the prompts where the brand is never included, since those are the clearest targets for new content and third-party coverage. Our guide on how to get your brand mentioned by AI covers the levers that raise it.
Examples of Brand Inclusion Rate
- A cybersecurity company tracks 200 buyer prompts and finds it is included for 31% of them on ChatGPT but only 12% on Perplexity, with most of the Perplexity gaps in compliance-related prompts.
- A hotel group splits brand inclusion rate by city and discovers that AI assistants recommend competitors for almost every family-travel prompt in Lisbon and Barcelona.
- A SaaS team counts a prompt as included only if the brand appears in at least three of five weekly runs, which drops its headline rate from 58% to 41% but gives a more stable trend line.
- A board report shows brand inclusion rate rising from 24% to 37% over two quarters after the company published new comparison pages and was added to several industry roundups.
