For B2B SaaS buyer queries, AI engines cite a recognizable mix of tech media, communities, review sites, and vendor blogs. In my AI-Search Visibility Benchmark, the most cited single domain was TechRadar with 48 citations, followed by G2 (28, including learn.g2), Reddit (25), HubSpot (21), Zapier (17), and Zoho (15). That sounds concentrated until you see the denominator: 1,055 citations spread across 508 domains. No site dominates. TechRadar leads, at roughly 4.5% of all citations.
I’m Andrii Byzov, a fractional CMO for B2B tech who runs AI search optimization for SaaS companies. This post ranks the domains AI actually cites, so you can see the practical target list for PR and generative engine optimization. The full methodology lives in the AI-Search Visibility Benchmark.
Key takeaways
- The benchmark covers 148 B2B SaaS buyer queries, producing 1,055 citations across 508 distinct domains in Perplexity and ChatGPT.
- TechRadar leads with 48 citations, about 4.5% of the total. That is the most cited domain, not a dominant one.
- The top of the list is a mix of four source types: tech media, communities, review sites, and vendor blogs.
- The long tail is real: with 508 domains in the set, citations are spread wide, so there is no single channel to win.
- Read as a target list, the top sources tell you where to focus PR, review-site, community, and content work.
The ranked list
Here are the most cited domains in the benchmark, with a rough source type for each. Counts come from 148 queries across two engines, so read them as directional rather than precise.
| Rank | Domain | Citations | Source type |
|---|---|---|---|
| 1 | TechRadar | 48 | Tech media |
| 2 | G2 (incl. learn.g2) | 28 | Review site |
| 3 | 25 | Community | |
| 4 | HubSpot | 21 | Vendor blog |
| 5 | Zapier | 17 | Vendor blog |
| 6 | Zoho | 15 | Vendor blog |
| 7 | PCMag | 9 | Tech media |
| 8 | Forbes | appears | Business media |
| 9 | Gartner | appears | Analyst |
| 10 | Semrush | appears | Vendor blog |
| 11 | Ahrefs | appears | Vendor blog |
| 12 | Salesforce | appears | Vendor blog |
| 13 | Freshworks | appears | Vendor blog |
| 14 | Amplitude | appears | Vendor blog |
| 15 | Helpscout | appears | Vendor blog |
I have listed exact counts only where I logged them cleanly. For domains marked “appears,” the benchmark confirmed they showed up in cited answers, but I am not going to invent a count I do not have. The honest version of this data matters more than a tidy column of numbers.
What the ranking actually says
A few things stand out, and none of them is “one site wins.”
TechRadar leads, but the lead is modest. Forty-eight citations sounds like a lot until you divide by 1,055. Roughly 4.5% of all citations went to the single most cited domain. So tech media earns attention, and TechRadar earns more than most, but no publisher is the gatekeeper. If you read one headline from this, it is that AI search rewards breadth, not a single placement.
Four source types share the top. The leaders are not all one kind of site. You have tech media (TechRadar, PCMag), a review site (G2), a community (Reddit), and a stack of vendor blogs (HubSpot, Zapier, Zoho, Semrush, Ahrefs, Salesforce). That mix is the real finding. AI engines pull from where buyers already look, and buyers look in all four places.
Vendor blogs show up more than people expect. A large share of the named domains are company blogs, not third parties. HubSpot, Zapier, Zoho, Semrush, Ahrefs, Salesforce, Freshworks, Amplitude, and Helpscout all earned citations with their own content. That is encouraging, because it is the one channel you fully control. Strong, answer-shaped content on your own domain can get cited, which is the practical case for how to write content for AI search.
The long tail is the headline nobody quotes. Five hundred and eight domains for 1,055 citations means most domains were cited once or twice. There is no shortcut where winning two sites wins AI search. The work is cumulative and spread out, which is exactly why it favors patient operators over one-off campaigns.
How to use this as a target list
Read the ranking as a to-do list, ordered by source type. Each one maps to a known play.
- Tech media and best-of lists. TechRadar and PCMag lead the media side. Getting included in roundups and category lists is a learnable motion, not luck. See how to get on best-of lists for AI search.
- Review sites. G2 sits near the top, and review platforms feed AI answers heavily. Claim and complete your profiles, and earn recent, specific reviews. More on that in review sites and AI search visibility.
- Communities. Reddit ranking third is not a surprise anymore. AI engines lean on community threads for candid buyer language. Build a genuine, useful presence rather than spamming, as covered in Reddit for B2B AI visibility.
- Vendor blogs. The most controllable channel. Publish content that answers buyer questions cleanly, with the entity clarity AI needs to attribute it to you.
That sequence is roughly how I prioritize AI search optimization work, because it moves from the slowest, most external levers to the fastest, most controllable ones.
The honest caveat
This is one benchmark: two engines, 148 queries, a single snapshot in time. Run a different query set, or the same queries next month, and the counts will move. Citation behavior changes as models update and as engines change which sources they trust. So treat this ranking as a strong directional guide to where AI looks for B2B SaaS, not a fixed leaderboard. No one controls these systems, which means the goal is always improved odds of being the cited answer, never a guarantee.

FAQ
Which sources does AI cite most for B2B SaaS? In the benchmark, the most cited domains were TechRadar (48), G2 including learn.g2 (28), Reddit (25), HubSpot (21), Zapier (17), and Zoho (15), with PCMag, Forbes, Gartner, Semrush, Ahrefs, Salesforce, Freshworks, Amplitude, and Helpscout also appearing. That is across 1,055 citations and 508 domains, so even the leader was about 4.5% of the total.
Does TechRadar dominate AI search for B2B SaaS? No. TechRadar led with 48 of 1,055 citations, roughly 4.5%. It is the most cited single domain in this set, not a site that owns AI search. Citations were spread across 508 domains, so leading is accurate and dominating is not.
How was this AI citation data collected? The numbers come from my AI-Search Visibility Benchmark, which ran 148 B2B SaaS buyer queries through Perplexity and ChatGPT and logged every cited source, producing 1,055 citations across 508 domains. Counts are directional and reflect this query set and these two engines.
How do I get my B2B SaaS cited by AI? Target the source types AI already trusts: tech media and best-of lists, review sites like G2, relevant community threads, and strong vendor-blog content. None of it guarantees placement, but it improves your odds of being the cited answer over time.
