AI の回答 301025 件のデータ調査:ChatGPT、Gemini、Perplexity、Claude、Grok が HubSpot をどのくらいの頻度で引用しているかを、13 か月にわたって月ごとに分析しました。

HubSpot is cited in 0.47% of measured answers over the last three months, which places it twelfth of the platforms tracked. It is cited by all five models, most often by Gemini at 0.78% and least often by Perplexity at 0.08%.
HubSpot is the clearest case of a content marketing engine losing citation share as the models diversified their sources.
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 gap between the model that cites HubSpot most and the one that cites it least is 0.7 points. That spread, not the average, is what should decide a budget: the same work returns most on Gemini and least on Perplexity. Across all tracked platforms, HubSpot ranks twelfth.
Over the 13 months measured, HubSpot moved from 0.96% in August 2025 to 0.37% in August 2026, with a peak of 2.45% in February 2026. Averaged over the first three months against the last three, the movement is minus 0.94 points.
A large blog library used to be a dependable way to be quoted on marketing questions. Over the measured period, that position eroded on every model in the panel, while review, video and community sources rose. The finding matters beyond one company: it suggests that generic top of funnel articles, however well produced, are being replaced by sources with first hand signal. For a marketing team, the implication is uncomfortable but simple, which is that another well written overview article is now the least likely format to be cited.
