Recommendation Placement Snapshot

Questions This Section Answers

• How does first-position recommendation strength differ between RingCentral and Nextiva despite similar coverage?

Coverage alone does not show how prominently a brand is recommended. The leading brands show different placement profiles.

RingCentral and Nextiva both hold high top-three rates, but RingCentral leads clearly in first-position placement at 44.5% in October 2026 versus 11.7% for Nextiva. Close coverage rates can still hide very different first-position strength.

Buyer-Intent Distribution

Questions This Section Answers

• Which buyer-intent classes does the current public series measure, and which remain uncovered?

In October 2026, all qualified observations fell into the Brand Recommendation class, covering discovery and consideration queries, consistent with July 2026.

The current public series measures the Brand Recommendation class of discovery and does not yet contain qualified observations in the Pricing & Value or Multi-Brand Comparison classes.

Historical Measurement Record

This is an evergreen benchmark URL. New measurements are added to the same report.

Evidence and Source Layer

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure:

• Market share or revenue attribution.
• Every possible AI response across all models and configurations.
• Organic search ranking performance.
• Social media mention volume.
• Private or sponsored channels.
• Causality from a metric movement alone.

Top 10 Cited Domains

Questions This Section Answers

• Which domains are cited most often across AI platform responses for VoIP Services?
• How concentrated are citations among the top cited domains?
• How many tracked brand domains appear among the top cited sources?

Across all AI platform responses in the October 2026 measurement period, 6,576 citations were observed across 928 unique domains.

Citations are broadly distributed rather than concentrated: the top 10 domains together account for roughly 35% of the 6,576 citations observed across 928 unique domains. Three tracked brand domains appear in the top 10: nextiva.com at rank 3, vonage.com at rank 4, and ringcentral.com at rank 7, with ooma.com just outside at rank 9. The mix skews toward official brand sites and technology review and comparison outlets such as pcmag.com and getvoip.com, alongside large general platforms like youtube.com, google.com, and reddit.com.
