What we observed in this categoryauto-generated
Apollo leads the lead enrichment tools category with a visibility score of 62.5%, more than 25 percentage points ahead of ZoomInfo and Clay, both sitting at 37.5%. The category average is just 8.1%, making Apollo's position statistically dominant. However, Apollo's visibility has fallen from 75.0% in the prior period, meaning its lead is narrowing. Six of the top ten brands, including Lusha, Clearbit, and RocketReach, register 0.0% visibility, indicating that Google AI Mode concentrates attention on a very small set of names.
The visibility-to-citation gap is striking across this category. Apollo, ZoomInfo, and Clay each hold meaningful visibility scores yet carry 0.0% citation rates. Cognism is the only brand in the top five that earns any citations at all, with a 12.5% citation rate, making it the sole brand AI Mode actively links out to despite its visibility falling 25 percentage points. This means Cognism is relatively trusted as a source even as it loses share of mentions, a divergence that separates named brands from cited brands clearly.
Google AI Mode is the top engine for every brand in this dataset, confirming the audit is concentrated on a single surface. The top cited sources, however, are dominated by third-party sites: gumloop.com, youtube.com, zapier.com, and cleanlist.ai all appear before most brand domains. Cognism.com is the only brand domain in the cited sources list. This pattern suggests AI Mode anchors its answers on workflow and integration content rather than vendor-owned pages, which explains the near-zero citation rates across the category.

Sources AI engines trust in this category

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.
