What we observed in this categoryauto-generated
HubSpot leads the marketing automation tools category with a visibility score of 62.5%, more than 25 percentage points ahead of second-ranked ActiveCampaign at 37.5%, and over seven times the category average of 8.8%. This gap is operationally significant: brands from rank 7 downward, including Adobe Marketo Engage, Klaviyo, and Insider, hold 0.0% visibility — meaning AI Overviews are effectively rendering them invisible to buyers conducting research queries in this category.
A structural anomaly defines this category: every brand, including HubSpot at rank 1, carries a citation rate of 0.0%. This means AI Overviews are naming brands extensively — HubSpot appears in 62.5% of responses — without sourcing their own domains as references. Being named in an AI answer and being cited as a trusted source are entirely decoupled here, suggesting AI familiarity with brand names is not translating into domain authority recognition within the generated responses.
The sources Google AI Overviews anchor on for this category are third-party review and comparison sites, specifically ventureharbour.com, g2.com, zapier.com, and gartner.com, alongside community platform reddit.com and niche directories like marketingautomation.tech. This pattern indicates AI is synthesising brand mentions from aggregator and review content rather than vendor-owned content, which explains why even dominant brands like HubSpot hold zero citation share despite high visibility.

Sources AI engines trust in this category
Across the 8 buyer-intent queries we ran on marketing automation tools, these are the domains Google AI Overviews cited most often. If you're not on this list — or if your competitors are — that's a concrete PR / linkbuilding target.
How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer.
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence — different from being named.
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps.
Rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 30 days and refresh this page automatically.
