What we observed in this categoryauto-generated

Nextiva dominates the unified communications AI visibility landscape with a composite score of 40.0, more than double RingCentral's 20.0 and over ten times the category average composite. Its visibility of 25.0% is the highest recorded, against a category average of just 3.8%, and its citation rate of 75.0% dwarfs all peers. This gap is significant: Nextiva is not merely leading — it occupies a structurally different tier from every other brand in the dataset, suggesting AI responses in this category are substantially shaped around its content.

CloudTalk presents the starkest divergence between visibility and citation in the dataset: it registers 0.0% visibility yet achieves a 50.0% citation rate, ranking third overall by composite score. Conversely, Zoom and Microsoft Teams each hold 12.5% visibility but record 0.0% citation, meaning AI responses mention them without anchoring sourced claims to their domains. This split reveals that being named in an AI answer and being trusted as a cited source are materially different outcomes, and CloudTalk currently earns the latter without the former.

All ten ranked brands share Google AI Mode as their top engine, and Nextiva's own domain appears first among the top cited sources, alongside gartner.com, google.com, ecosmob.com, ringcentral.com, and cloudtalk.io. The presence of gartner.com and ecosmob.com as top cited sources indicates that AI responses in this category draw on third-party analyst and comparison-site content, not solely brand-owned pages. Brands absent from these external sources — such as Webex, which scores 0.0 composite — appear to receive no AI traction regardless of market prominence.

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.
