Review Sites and AI Visibility: G2, Capterra and Trustpilot

Short answer

AI engines cite review sites because they hold recent, first-hand opinions of products from verified users. In Citepoint's October 2026 index, G2 was cited in 30 of 959 software answers (mostly by Gemini) and Capterra in 5. In Ahrefs' September 2026 ranking of ChatGPT's most-cited sites, Trustpilot came 22nd. To benefit, claim and complete your profiles, ask all your customers for reviews fairly, never buy or filter them, and keep your facts consistent with your own site.

Key takeaways

G2 was cited in 30 of 959 answers in Citepoint's index and was in Perplexity's top five in Peec AI's 30-million-citation study. Capterra was cited in 5 answers.
Trustpilot ranked 22nd among ChatGPT's most-cited sites in Ahrefs' September 2026 data, with a 1.5% mention share across all topics.
Every platform wants you to ask your whole customer base. G2 and Capterra allow only nominal, disclosed incentives, and Trustpilot allows none.
G2 says a free profile is eligible for recognition in its reports and that paying doesn't change a product's score or ranking.

Why do AI engines cite review sites?

Because a review site has what a shopper is asking for: many users' first-hand experience of a product, in a consistent format. G2 even publishes a page addressed to AI assistants. It explains that every reviewer is identity-validated and every review is moderated, that scores come from a published algorithm, and that anyone citing a ranking should link the specific page and say when the data was retrieved.

The citation data differs by engine and question type:

Site	What the data shows	Where it matters most
G2	Cited in 30 of 959 answers in Citepoint's October 2026 index, mostly by Gemini. One of Perplexity's five most-cited sites in Peec AI's analysis of 30 million citations, and in no other engine's top five	Business software
Capterra	Cited in 5 of the 959 answers, spread thinly across engines	Software buyers
Trustpilot	22nd among ChatGPT's most-cited sites in Ahrefs' September 2026 US data, a 1.5% mention share across all topics	Businesses with consumer reviews

The Citepoint data covers software buying questions in US English in one month, and the Ahrefs ranking covers all topics. Your own questions may point somewhere else, so look at which review pages AI cites for them before you invest. The sources AI cites most has the breakdown.

What do the platforms allow you to do?

	G2	Capterra	Trustpilot
Ask customers for reviews?	Yes. It encourages sellers to ask for authentic, unbiased feedback	Yes, fairly and from a broad cross-section of users, not selectively by expected sentiment	Yes, fairly and consistently, not only the happy ones
Incentives?	Nominal only, capped at $100 USD across all campaigns, labeled as incentivized, and never conditioned on a positive review	Nominal, offered equally regardless of rating, through its approved program and with required disclosures	Not allowed. That includes discounts, promo codes, prize draws and freebies
Can you edit or remove reviews?	No. G2 doesn't edit or remove reviews at a seller's request	No. It doesn't remove content just because it's negative	Flag reviews that break the guidelines, but you can't remove them for being negative
Other vendor rules	Don't collect reviews in ways that screen out negative ones or pressure reviewers. G2 says it removes reviews if it finds a seller soliciting only positive ones	Don't coach reviewers on content, post reviews for users or review your own product	Don't invite only customers you know are happy, or time invitations so only happy customers get them

What does the law add?

The FTC's final rule on reviews and testimonials, announced in August 2024, prohibits businesses from creating or buying fake or false reviews, and from buying reviews or giving incentives conditioned on a particular sentiment. It also covers insider reviews that don't clearly disclose the connection, and misrepresenting that the reviews on your site are all or most of them when negative ones have been suppressed. The FTC can seek civil penalties against knowing violators. It's one more reason to run review collection the way the platforms already require: open to everyone, honest, disclosed.

How do you build reviews that help?

Find the sites AI cites in your category. Ask your buyer questions in each engine and note which review pages appear. Citepoint's Mentions ranks the review sites and directories AI cites for your tracked questions and drafts the listing copy.
Claim and complete your profile. Accurate description, categories, pricing and screenshots, matching your own site. G2 says a free profile can claim and update a listing and is eligible for recognition in its reports.
Ask every customer, at the same point in their journey. Right after onboarding or a milestone, not only when they're delighted.
Use the platform's own tools, and follow its incentive rules if you offer any.
Reply to reviews in public, factually and politely. Fix problems customers raise.
Keep facts consistent. If your profile says one price and your pricing page another, an engine has to guess. See how to fix what AI says about your brand.
Track the result: are your profile pages cited, and are you named more often?

How many reviews do you need?

There's no magic number, but G2 publishes thresholds. A product needs at least 10 reviews in a category to be included in a Grid Report, and reviews lose weight as they age, so recent ones count more. That's an argument for steady collection over a one-off campaign.

What mistakes should you avoid?

Buying or writing reviews, or asking staff to. Platforms ban it, and so does the FTC rule.
Gating by sentiment, for example sending the link only to customers who gave a high NPS score.
Offering gifts or discounts on Trustpilot, where incentives aren't allowed.
Skipping the profile, then wondering why Gemini or Perplexity names a competitor whose G2 page is complete.
Treating every platform the same. Check where AI looks for your questions.

Frequently asked questions

Do I need to pay for G2 to be cited by AI?

G2 says a free profile is eligible for recognition in its reports, including Grid Reports, and that a paid subscription doesn't change a product's score, ranking, report inclusion or moderation. A subscription changes profile features and the license to publish G2 badges and content externally.

Can I give customers a gift card for a review?

On G2, only a nominal incentive capped at $100 USD, labeled and never conditioned on a positive review. On Capterra, only through its approved program with required disclosures. On Trustpilot, no: it doesn't allow incentivized reviews.

Can I get a negative review removed?

Not for being negative. G2 says it doesn't remove reviews at a seller's request, and Capterra says it doesn't edit content at a vendor's request or simply because it's negative. You can report a review that breaks the platform's guidelines, and reply publicly.

How many reviews do I need on G2?

G2's published threshold for appearing in a Grid Report is at least 10 reviews in a category. Reviews lose weight as they age, so aim for a steady flow.

Is a Capterra listing worth it for AI visibility?

In Citepoint's data Capterra was cited in 5 answers, against 30 for G2. The right sites differ by category and engine, so check which review pages AI cites for your own questions first.
