マーケティング分野の AI 引用調査：AI の回答 25295 件を測定

The short answer

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.

• Gemini: HubSpot at 4.31%
• Perplexity: YouTube at 3.09%
• Claude: HubSpot at 2.6%
• Grok: HubSpot at 4.55%

How to read these numbers

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.

What changed over the measured period

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.

HubSpot month by month in this sector

• May 2026: 2.7%
• June 2026: 2.99%
• July 2026: 2.77%
• August 2026: 2.21%

What this means in practice

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.

How to use this study

1. Publish at least one piece per quarter built on data only you have, rather than another overview.
2. Consolidate duplicate posts on the same topic into one reference page.
3. Keep a public review profile: it now competes with blog content for the same answer slots.

How this study was measured

1. We run a panel of buyer questions every month, the questions people type before choosing a supplier.
2. Every question is sent to five AI: ChatGPT, Gemini, Perplexity, Claude and Grok.
3. Every answer is parsed, every cited source is extracted and normalised to a domain and a platform.
4. The citation rate is the number of citations of a source per 100 measured answers, computed per model so an uneven number of answers per model never distorts a column.
5. The month is closed, the dataset is rebuilt, and the public files are republished on data.sorank.com.

Limits of this study

1. This panel is not a neutral sample of the web. The questions come from the sectors our users operate in.
2. The panel leans French: 237930 answers come from questions asked in French and 63095 from questions asked in English.
3. Model coverage is uneven: 87008 answers from ChatGPT, 87004 from Perplexity, 87000 from Gemini, 20011 from Claude and 20002 from Grok. The two smallest samples are read as direction rather than as precise values.
4. A citation is not a click. This study measures what the AIs cite, not what a reader does next.
