G2, Capterra and Trustpilot in AI Search: How Review Sites Shape ChatGPT Answers

Ask an AI assistant for the best software in any category and there is a good chance the answer leans on G2, Capterra or Trustpilot. Review sites are where AI goes to check what real users think, and they quietly shape which brands make the shortlist. We measured how often each AI engine cites them and which review pages it uses.

TL;DR: Across 167,514 AI answers with sources (August to November 2026), review sites appeared in 15.5% of ChatGPT answers, 13.6% of Perplexity, 9.6% of Google AI Mode and 6.4% of Gemini. G2 is the most cited review site in every engine. Almost half of G2 citations point to a product's reviews page, and a fifth to category rankings. ChatGPT also searches review sites by name. SupaIntent Review Radar shows which review pages shape the answers about your category.

How often AI engines cite review sites

Share of answers with sources that cite at least one review platform (G2, Capterra, Trustpilot, Gartner Peer Insights, TrustRadius, GetApp or Software Advice):

ChatGPT relies on review sites more than any other engine. Google AI Mode cites them less because it leans on YouTube and Reddit instead. If you sell to buyers who use ChatGPT, your review profiles are part of your AI visibility.

G2 leads, Trustpilot and Capterra follow

G2 is the first stop for software questions in every engine. In ChatGPT it is the single most cited domain across all our answers, ahead of reddit.com. Trustpilot matters most for consumer and B2C brands, where it is often the only review source AI can find. Capterra is smaller but steady, and its pricing and profile pages show up when AI compares costs.

Here is what that looks like in Google AI Mode on November 4, 2026: asked for the best CRM software on G2, the answer quotes G2 ratings and review counts for each vendor and cites three G2 pages.

Which review pages AI cites

We classified every cited URL on G2, Capterra and Trustpilot by page type.

Two page types do most of the work. Product review pages are where AI checks what users like and dislike about a specific brand. Category pages are where it builds a shortlist. On Trustpilot nearly every citation is a company's review page; on Capterra review pages lead (45%), followed by product and pricing profiles (31%).

The practical consequence: your G2 reviews page and your position on the G2 category page for your main category are two of the most important pages about you on the internet, and you do not own either of them.

ChatGPT searches review sites by name

ChatGPT does not only stumble on review pages. In the 17,962 web searches we captured from ChatGPT, 4.4% named G2, Capterra or Trustpilot directly, for example Pipedrive reviews complaints negative G2 Capterra Trustpilot or site:g2.com Pipedrive reviews cons complaints. When ChatGPT looks for strengths and weaknesses of a brand, it goes straight to review sites. Read more about these searches in how to get cited in ChatGPT.

How Review Radar shows your review footprint

Your G2 dashboard shows traffic and reviews. It cannot show you which review pages AI uses when it answers your buyers, including pages about competitors. SupaIntent Review Radar starts from the AI answers.

In this CRM project, which tracks Pipedrive against HubSpot, Salesforce and Zoho CRM, 11 of 90 recent AI answers (12.2%) cited a review platform. G2 holds 80% of those citations. The most cited page is G2's "Best CRM Software" category ranking, cited 7 times by Gemini and Google AI Mode. Capterra's Pipedrive and HubSpot pricing pages follow. For every prompt you track, Review Radar records:

• review reach: the share of answers that cite a review platform;
• each platform with pages, citations, AI engines and share;
• the brands mentioned in answers that cite review sites;
• the most cited review pages, with the answers that cited them.

A review site playbook for AI search

1. Find the review pages AI already cites. Start with your category page and your own reviews page on G2, then the platforms Review Radar lists for your prompts.
2. Complete and update your profiles. Pricing, features, integrations and screenshots on G2 and Capterra are what AI quotes when it compares vendors. Outdated pricing there becomes outdated pricing in ChatGPT.
3. Keep reviews coming. Category rankings and dates on review pages reward recent reviews. Ask happy customers regularly, not in one campaign a year.
4. Answer the negatives. ChatGPT searches for "cons" and "complaints". Reply to critical reviews and fix the issues they name, because those lines end up in AI answers.
5. Win the alternatives and comparison pages. If buyers ask for alternatives to a competitor, check whether you appear on that competitor's G2 alternatives page.
6. Measure answers, not stars. Watch your share of AI answers for the prompts tied to your category, and which review pages they cite.

How to choose a tool to track review sites in AI search

1. It shows exact review pages, not only the g2.com domain.
2. It covers ChatGPT, Google AI Mode, Gemini and Perplexity, because they rely on review sites very differently.
3. It links pages to brands and answers, so you see who benefits from each cited page.
4. It sits next to prompt tracking, citations and sentiment, so you can see what changes in the answers.
