Software review sites are turning their ad products into a channel aimed at AI answers. G2 said on November 10 that advertising now runs across G2, Capterra, Software Advice and GetApp from one campaign, and it named a paid category, answer engine marketing, for influencing which brands AI answers mention.
What G2 announced
In its release, G2 described a unified platform across the four review sites it now owns. The company says the combined platform holds more than 6 million reviews across 2,000+ categories and reaches 200 million annual buyers. Vendors can manage profile listings, review collection, advertising campaigns, lead generation, intent signals, badges and custom content for all four properties in one place.
The four sites came together through a deal G2 announced in January, when it agreed to acquire Capterra, Software Advice and GetApp from Gartner. That release promised a more mature advertising setup and a pay-per-lead offering built on a larger pool of buyer intent data. The November release is the first time the ad products are sold as one buy across the four sites.
G2 also put a name on a practice many vendors already pay for in pieces. The release defines answer engine marketing (AEM) as “the discipline of using paid tactics to influence which brands appear in AI-generated answers.” G2 presents AEM alongside answer engine optimization (AEO), the unpaid work of making a brand easy for AI systems to find and cite.
Alexis Zheng, Chief Product & Technology Officer at G2, put the company’s case this way: “AI is the curtain, and all that gets through is the evidence. So, we built the full stack to help brands win the answer.”
Why review sites sit close to AI answers
The claim behind the product is that AI answer engines lean on third-party sources when they recommend a product. G2 states it in its own release: answer engines “base their answers on credible, third-party evidence,” and G2 describes itself as the most-cited B2B software source across AI search platforms. That second statement is G2’s own and the release does not publish the data behind it.
Independent data from another category points the same way. Cision’s State of Search and Social 2027 report, released on November 9, looked at AI responses to “best car” queries. Toyota led with a 13.8% share of brand mentions, yet its own website accounted for a fraction of the sources the models cited, against more than 4,000 citations for YouTube. Cision found the most-cited sources were YouTube creators, editorial brands and individual journalists, ahead of the carmakers themselves. Cars are a consumer category and software is a business one, so the finding is a direction for B2B, and the exact shares will differ.
We have tracked this split between ranking and citation before, in AI Overviews Are Citing a Different Web Than Search Ranks. Review sites are one of the third-party sources that benefit, and G2 is now pricing that position.
What changes for vendors who buy review-site ads
One campaign, one budget
G2 Ads Clicks, the pay-per-click program where vendors bid to reach buyers researching their category, now runs with one campaign, one budget and one conversion tracker across all four sites. New campaigns cover all four automatically, and G2 says the platform optimizes for the most clicks within budget. Paid Promotions on G2.com are also managed from the same my.G2 account.
For a vendor that bought Capterra and G2 separately, this changes the unit of purchase. Budget that used to be split by site now goes into one pool, and G2’s optimizer decides where the clicks come from. The release does not say whether vendors can still cap spend on a single site, so that is a question for the account team before renewal.
Clicks that become account names
G2 Ads Clicks Plus, an add-on for eligible customers, de-anonymizes clicks across the four sites and adds firmographic and location signals. G2 calls it its highest-intent signal, because the buyer has already clicked through to the vendor’s landing page, and says customers can retarget and nurture the accounts that engage. This sits next to G2’s Buyer Intent data, which the company has extended to all four sites, and Verified Leads, its lead-generation product.
Research reports that double as AI evidence
G2 also tied its AI Custom Research reports, which add buyer interviews, to Content Studio, a beta tool that turns those reports into assets for LinkedIn, Reddit and Instagram. G2 says the reports “also serve as additional evidence for AI answer engines.” Max Gordon, Global Campaigns Director at Tanium, said in the release: “We’ve used it globally through H2 2026, and it accounted for 28% of all our content downloads worldwide in September.”
The release also lists G2 Agent Evaluations, which entered public beta in September with a Customer Experience Agents category and has published early results for Voice AI Agents.
What it means for the marketing leader
In our reading, the useful part of the announcement is the definition. Once a review platform sells “paid tactics to influence which brands appear in AI-generated answers,” AI visibility has a paid line in the media plan as well as an earned one. A demand generation team that already funds review-site ads and review collection should expect that spend to be pitched again as AI visibility, with a different set of metrics attached.
That makes the measurement question sharper. Clicks, leads and intent signals are things G2 can report from its own sites. The effect of a paid placement on what ChatGPT, Gemini or Perplexity later say about a category happens on systems G2 does not control, and the release gives no method or figure for that effect. Our earlier piece, AI Visibility Advertising Is Three Bets, Not One Channel, set out why those bets need separate scorecards.
Review volume still matters on its own terms. Rankings built on reviews, such as the ones we covered in SAP CX Sweeps G2’s Fall 2026 Rankings, are the evidence G2 says AI engines read, and that evidence comes from customers, whatever a vendor spends on ads.
How to evaluate the offer
Before moving review-site budget into the unified campaign, get four answers in writing from the account team:
- Whether spend can be capped or excluded by site, and whether the conversion tracker reports results by site.
- How G2 keeps paid placements separate from the review data that AI systems may ingest, and where that separation is documented.
- What Clicks Plus shares about the person behind a de-anonymized click, and the consent basis for sharing it.
- What evidence G2 will provide that AEM spend changed answers on a named AI platform, as distinct from clicks on G2’s own pages.
Then run the test that does not depend on any vendor. Pick ten buying questions in your category, ask them in the AI assistants your buyers use, and log which sources each answer cites. Repeat monthly. If review sites show up in the citations, review collection is worth funding. Whether paid AEM moves those citations is something the log can show over a quarter.
