When AI engines like ChatGPT, Claude, and Perplexity answer questions about B2B lead generation agencies, Belkins comes up most often, appearing in 37.5% of AI-generated responses across the engines we tracked. Martal Group and Callbox also rank among the most frequently mentioned, but Belkins holds a clear lead in both visibility and how often it gets cited as a source.
The rankings reflect which sources AI engines trust most. The top cited domains include clutch.co (a third-party review aggregator), youtube.com, pipeline.zoominfo.com, callboxinc.com, and bookyourdata.com. Because review aggregators like Clutch carry heavy weight, agencies with strong, recent review profiles on those platforms tend to surface more often, regardless of how good their own website content is.
For a buyer using this list, the most practical signal is third-party validation on review platforms like Clutch. An agency that consistently earns detailed, recent client reviews on aggregator sites is more likely to appear when your own team or a colleague asks an AI for recommendations. Check each agency's Clutch profile for recency and volume before making a shortlist decision.
At a glance
What we observed in this categoryauto-generated
Belkins leads the B2B lead generation agencies category with a composite score of 33.8, visibility of 37.5%, and citation of 25.0%. The category average sits at just 6.9% for both visibility and citation, meaning Belkins is running at more than five times the average on visibility alone. Martal Group holds second place at a composite of 25.0, and the gap between rank 2 and rank 5 (SalesRoads, composite 12.5) is already substantial, suggesting the top two brands are pulling away from the rest of the field.
Callbox presents the clearest divergence between named visibility and citation trust in this dataset. Its visibility stands at 12.5% but its citation rate reaches 37.5%, the highest citation figure of any brand in the top 10. CIENCE shows the opposite pattern: 25.0% visibility paired with 0.0% citation, meaning Google AI Mode surfaces it in answers but does not anchor source links to its domain. This split between being named and being cited indicates the AI treats these two brands very differently as evidence sources.
Every brand in the top 10 lists Google AI Mode as its top engine, confirming this category's AI visibility is concentrated in a single channel. Among the top cited sources, callboxinc.com, belkins.io, and martal.ca appear alongside third-party domains including clutch.co, youtube.com, pipeline.zoominfo.com, and bookyourdata.com. The presence of review and data aggregator domains in the citation list suggests Google AI Mode is drawing heavily on third-party authority signals rather than relying solely on agency-owned content.

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. More on visibility →
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. More on citation rate →
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. How AI engines pick sources →
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. How AI search ranking works →
