Are Software Review Platforms More Visible at the Bottom of the Funnel?

Are Software Review Platforms More Visible at the Bottom of the Funnel?

Summary

An analysis of approximately 35,000 ChatGPT citation URLs in Profound reveals that citations from review platforms increase significantly with stronger purchase intent. Within these citations, G2 and its acquired brands — Capterra, Software Advice, and GetApp — together hold an 84% share of citations in the review-platform category. This demonstrates that as buyers progress further into their decision-making process, AI models rely more heavily on verified, peer-generated content from the G2 portfolio to guide their recommendations.

Why This Matters

The buyer journey now begins with a prompt rather than a demo request. Because citations provide observable evidence behind AI recommendations, appearing in the right sources is critical for brands to be considered.

AI-generated answers intentionally mention software vendors, but the key question is which third-party sources they cite. A higher number of citations from review platforms as intent intensifies supports the idea that verified reviews and buyer validation become increasingly influential deeper in the funnel.

Hypothesis

As the strength of purchase intent grows, the likelihood that an AI response cites a review site (e.g., G2 or TrustRadius) rises more than citations to vendor sites or other third-party sources.

Methodology

Data and Scope:

  • Source: Approximately 35,000 Profound citations
  • Region: United States only, from ChatGPT responses
  • Time frame: December 2025

Step 1: Assign Intent to Each Prompt

Each prompt was classified into one exclusive user journey stage—Discovery, Exploration, Evaluation, Focused Evaluation, or Other—then normalized and mapped to a single intent level.

TL;DR: 

Review-platform citation share increases meaningfully with stronger purchase intent, based on an analysis of ~35,000 ChatGPT citation URLs captured in Profound. Within these citations, G2 and its recently acquired brands — Capterra, Software Advice, and GetApp — collectively command 84% share of citations in the review-platform category. This confirms that as buyers move deeper into the funnel, AI models increasingly rely on the verified peer-generated sources found across the G2 portfolio to inform their recommendations.

Why this matters

The buyer journey no longer starts with a demo request; it starts with a prompt. Because citations are one of the few observable evidence layers behind an AI recommendation, they represent where a brand must show up to be considered.

AI answers mention software vendors by design. The more interesting question is which third-party sources those answers cite. If review platforms are cited more as intent strengthens, that supports the idea that verified reviews and buyer proof become more influential deeper in the funnel.

Hypothesis

As intent strength increases, the probability that a review site (such as G2 or TrustRadius) is cited increases more than for vendor sites or other third parties.

Methodology

Data and scope:

  • Source: ~35,000 Profound citations
  • Coverage: US only, ChatGPT only
  • Time window: December 2025

1) Assign intent to each prompt

Each prompt was classified into one mutually exclusive user journey step (for example: discovery, exploration, evaluation, focused evaluation, or other), then normalized into a prompt key and mapped to a single intent.

2) Convert citations into analyzable units at the domain level

For each citation URL, I extracted the root domain and classified it into a site type:

  • review_platform (G2, Capterra, GetApp, Software Advice, TrustRadius, Gartner as review context)
  • ugc_platform (Reddit, Wikipedia, Quora, YouTube, LinkedIn)
  • publisher (media, blogs, editorial sites)
  • vendor_or_other (vendors plus everything not mapped explicitly)

3) De-duplicate domains within each run

  • To avoid a single response over-weighting a domain via multiple URLs, I de-duplicated to one record per run_id × intent × domain.

4) Compute shares

  • Primary view: For each intent stage, compute the share of unique cited domains by site type.
  • Secondary view: Within the review_platform subset, compute share by review domain (G2 vs Capterra vs others), overall, and by intent.

Results

A) Citation mix by site type

Vendors dominate citations in every stage (about 67% to 74%). That makes sense because the prompts we looked at asked for vendors.

However, the closer we get to a purchase in the buyer journey, the more prevalent and influential platforms like G2 become, thanks to a significant share of authentic peer reviews and UGC. Review-platform citation share rises to 13.2%, roughly 1.8× discovery’s 7.4%. Meanwhile, vendors see lower influence on those decisions at this same stage.

Review platforms are cited more than publishers (8.6% vs 4.0%).

B) Review-platform share split by brand

Within review-platform citations, G2 is the most frequently cited domain by a wide margin in this sample and timeframe.

Since G2’s acquisition of Capterra, Software Advice, and GetApp, it has established a dominant presence in AI-driven discovery. Here is the combined overall share across major review domains:

  • G2 ecosystem (g2.com + acquired brands): 84%
  • gartner.com: 13%
  • sourceforge.net: 2%
  • trustradius.com: 1%
  • trustpilot.com: ~0%

This indicates that AI citations from review sites are a strong bottom-of-funnel lever for software vendors, particularly when they come from a major player like G2.

Win with trust

The data confirms that review sites are most effective at the bottom of the funnel. When software buyers reach the evaluation stage of their journey, the recommendations they see from AI increasingly stem from trusted peer proof sourced from platforms like G2.

With G2’s now significant influence on LLM citations and AI search visibility, there is a strong case for vendors to maintain a steady presence across the G2 ecosystem. This ensures that when AI looks for the final layer of evidence to recommend a product, it finds a wealth of authentic customer voices.
