Data study of 25295 AI answers in Marketing: which platforms the AIs cite in this sector, how it differs from the general ranking, and what to do about it.

In Marketing, 25295 AI answers were measured between May 2026 and August 2026. The most cited platform is HubSpot at 2.6%, ahead of Trustpilot at 2.09%. That ranking differs from the general one: HubSpot is cited 5.5 times more here than in the general ranking.
Marketing is the sector where a single content platform still leads, and where that lead has been shrinking every quarter.
A citation rate of 2% means the source was cited twice for every 100 measured answers. Rates are computed per model against the number of answers of that model, so a model with a smaller sample never distorts a column. A source cited several times inside one answer is counted once per company block, which keeps a single verbose answer from dominating a month.
The distribution is worth as much as the ranking. The top three sources hold 44% of the citations counted in this table, 9 platforms sit above 1%, and HubSpot is cited 1.2 times more often than Trustpilot. A market where three sources hold most of the citations rewards depth on those three rather than presence everywhere.
This sector was measured on 25295 answers, 54.9% of them in French, across all five models (ChatGPT, Gemini, Perplexity, Claude, Grok). The language mix matters when you read the ranking, because local platforms weigh more in French speaking markets.
This sector was measured over 4 months, between May 2026 and August 2026, on 25295 answers, and 32 platforms recorded at least one citation. Its leading source, HubSpot, fell from 2.7% in May 2026 to 2.21% in August 2026, which is the kind of movement that makes a ranking older than one quarter unreliable.
Marketing questions still pull vendor blogs and software documentation, but the concentration is falling as review and community sources climb. For an agency or a software vendor, that means the classic playbook of publishing another overview article is now the least differentiated move available. What holds up is content with a first hand ingredient: original measurements, tests, screenshots, or numbers nobody else can publish. This study is itself an example of the format that gets cited in this sector.

Because they publish documentation and definitions that answer the question directly, and they have done it for years. The gap is closing as the models add review and community sources to the same answers.
