Most "review platform comparison" content stops at user counts and pricing. In 2026 the more strategic question is: which platforms feed AI Overviews, ChatGPT Search and Perplexity? We tested 17 platforms across 8 industries to find out. Here's the cut.
Methodology
For each platform we tested whether: (1) the platform's own pages are cited in AI answers for relevant queries, (2) review content from the platform appears as sourced text in AI summaries, (3) brand profiles on the platform contribute to the brand's AI-mention rate.
Each platform was scored 0–10 on AI citation contribution per industry.
The 2026 AI-citation tier list
Tier 1 (8+/10): Foundational. Google Business Profile, Trustpilot, G2.
Tier 2 (6–7/10): Industry-defining. Capterra (SaaS), Healthgrades (medical), Avvo (legal), Houzz (home), TripAdvisor (hospitality), Booking.com (lodging).
Tier 3 (4–5/10): Useful but not pivotal. Yelp, Facebook, Thumbtack, Clutch, Shopify reviews, BBB.
Tier 4 (≤3/10): Reputational hygiene only. Zocdoc, Glassdoor (employer only).

Why Google sits above everything
Across all 8 industries, Google Business Profile was the single highest AI-citation contributor. The reason is structural: Google operates both the search engine surface AND the canonical local business database that AI engines (including non-Google ones) cross-reference.
If you fix one platform first, fix Google. Then layer industry-specific platforms on top.
