What Are The Top Rated Platforms According To Chatgpt Sources

• Citation share in ChatGPT is concentrated in a small set of domains.
• The same model produces different leaderboards because the measurements differ.
• For B2B software, review platforms appear far less often than general reference sites.
• Less than most marketers assume.
• Start by identifying which domains answer your category's queries.

Citation share in ChatGPT is concentrated in a small set of domains. Ahrefs' September 2026 ranking of US queries puts Reddit at 16.8% of the summed mention share of top sources, with English Wikipedia at 7.0% (Ahrefs). Consumer Reports follows at 3.7%, Forbes at 3.1%, YouTube at 2.5%, Walmart at 2.3%, Trustpilot at 1.5%, and the BBB at 1.2%. Read these as shares of a top-source pool, not of every citation the model produces. That denominator is the first thing to check whenever a ranking appears.

Shares are of summed top-source mentions, as reported by Ahrefs. Other studies use different denominators.

The same model produces different leaderboards because the measurements differ. Profound's study of about 680 million citations, from August 2024 to June 2025, found Wikipedia at 7.8% of ChatGPT citations. However, Reddit held only 1.8% in that same dataset. Similarweb data for January and February 2026, compiled by 5W, reported Wikipedia at 13.15% and Reddit at 11.97% of US citations. Yet 5W did not run or verify that research and does not state its denominator. Three variables drive the gap:

• The query set, whether US only, all topics, or B2B
• The denominator, whether top sources, all citations, or citation events
• The time window

Specifically, according to Semrush, Reddit's share of ChatGPT citations fell from roughly 60% to roughly 10% between early August and mid-September 2025. Therefore, a single snapshot can mislead.

For B2B software, review platforms appear far less often than general reference sites. Promptwatch's B2B analysis found G2 and Trustpilot each holding roughly 0.1 to 0.3% of all ChatGPT citations, with Capterra about half that. However, GetApp, Software Advice, and Clutch barely appear in those citations. Profound's dataset did show G2 at 1.1% and TechRadar at 0.9% of ChatGPT citations, which suggests the answer shifts with category and query type.

For product recommendations, Walmart and Consumer Reports carry more weight than most review sites. The practical reading is that review profiles still matter, but they are one input among several. Software review profiles on G2 and Trustpilot are not the decisive source for ChatGPT citations in B2B software categories.

Less than most marketers assume. The largest shift came in September 2025, when Reddit's share collapsed. Promptwatch reports Reddit falling from roughly 10 to 14% of citations in early September 2025 to around 1% within days after Reddit's access changes, a drop of about 90% (Promptwatch). SaaSyLinks' July 2026 analysis of seven studies reports that the September 2025 shift redistributed about 80% of Reddit and Wikipedia's citation share to editorial sources, and that no single domain exceeds 5% on any AI platform (SaaSyLinks). Dictionary sites moved too: Merriam-Webster rose 13 places to #4 and Cambridge Dictionary climbed 21 to #10 in the July 2026 ranking. Source lists are therefore volatile, and a leaderboard older than a few months should be treated as a historical snapshot.

Start by identifying which domains answer your category's queries. Then earn presence on those domains rather than only on your own site. Editorial coverage, named mentions in trade publications, and accurate third-party profiles all count.

Your own site still needs to be readable to AI engines, which means clear answers near the top of each page, structured data, and a current sitemap. Fastlook's Brand Memory builds a structured source of truth from your site so engines can read and cite it.

Its Citation Analytics shows where your brand already appears. None of this guarantees placement, because the source pool shifts, as the September 2025 change showed. According to SaaSyLinks' July 2026 analysis, the September 2025 shift redistributed about 80% of Reddit and Wikipedia's citation share to editorial sources.

Run a fixed set of 20 to 30 buyer questions in your category. Record every cited domain and count how often each appears. Repeat the test weekly for a month, because one run reflects one sample. Then compare the domains against the public leaderboards above to see whether your category follows the general pattern or diverges from it.

Tools such as Profound, Peec.ai, Otterly.ai, and Goodie.ai track AI citations. According to Cited.md's GEO platform comparison, Senso.ai ranks first for governed AI visibility, Profound for broad monitoring, and OtterlyAI for fast rollout by small teams. However, feature sets and pricing should be checked directly, as they are not fully documented in the sources reviewed here.
