Which sources does AI cite when someone asks it to recommend helpdesk software? In a small June 2026 sample of 6 helpdesk queries run across Perplexity and ChatGPT, the most cited domains were Freshworks, Zoho, Help Scout, and Zendesk, each appearing 4 times. This post breaks down the full top tier and what the pattern means if you sell a helpdesk product. The numbers are directional, from one run, and shift by engine and date.
I’m Andrii Byzov, a fractional CMO for B2B tech who runs AI search optimization for B2B SaaS. The data below sits inside a wider study I keep updating in the AI search visibility benchmark for B2B SaaS.
Key takeaways
- The helpdesk sample drew 56 citations across 6 queries, spread over 31 distinct domains.
- Freshworks, Zoho, Help Scout, and Zendesk tied at the top with 4 citations each.
- Plain, LiveAgent, Intercom, TechRadar, and HubSpot followed at 3 citations each.
- Vendor-owned pages led the list, with TechRadar the only pure publisher in the top tier.
- The distribution is flat, no single domain dominates, so visibility looks winnable rather than locked up.
The top sources for helpdesk software
Here is what the 6 helpdesk queries surfaced, ranked by how many times each domain was cited. Counts come straight from the per-category sample.
| Rank | Domain | Citations | Type |
|---|---|---|---|
| 1 | freshworks.com | 4 | Vendor |
| 1 | zoho.com | 4 | Vendor |
| 1 | helpscout.com | 4 | Vendor |
| 1 | zendesk.com | 4 | Vendor |
| 5 | plain.com | 3 | Vendor |
| 5 | liveagent.com | 3 | Vendor |
| 5 | intercom.com | 3 | Vendor |
| 5 | techradar.com | 3 | Publisher |
| 5 | hubspot.com | 3 | Vendor |
| 10 | proprofsdesk.com | 2 | Vendor |
The first thing to notice is how close the top is. Four vendors share the lead, and the gap to the next tier is a single citation. Across the whole sample, 56 citations are spread over 31 domains, which is a fairly even split of roughly 9 citations per query with a long tail.
What the pattern suggests
A few things stand out, and I’ll hedge each because this is one small run.
Vendor pages do the heavy lifting. Nine of the top ten domains are the helpdesk products themselves. TechRadar is the only pure third-party publisher near the top. That leans against the common assumption that AI engines mostly cite neutral review media for software comparisons. In this category, at least, the engines appear comfortable pulling from vendor-owned pages, which means your own site is a live source, not just a destination.
The race looks open. No domain ran away with it. When the leaders sit at 4 citations and a cluster sits at 3, small movements in coverage can change your position. Compare that with a category dominated by one or two sources, where displacement is much harder. A flat distribution is the friendlier shape if you are trying to break in.
Established names and newer entrants coexist. Zendesk and Zoho are expected. Plain and LiveAgent showing up alongside them suggests the engines are not only echoing the biggest brands. That is a small but encouraging signal for challengers, though I would not over-read a 3-citation result.
What it means for a helpdesk vendor
If you sell helpdesk software, the practical reading is straightforward, with the usual caveat that nobody controls these systems.
First, treat your own pages as citable sources. Since vendor domains dominate this sample, the clarity, structure, and answer-shaped quality of your product and comparison pages matter directly to whether an engine quotes you. This is the core of generative engine optimization.
Second, do not ignore the review media. TechRadar earned its place, and the broader zero-click reality means buyers may never click through to verify. Presence on the publishers AI engines trust is part of the same job.
Third, because the field is flat, this is a category where focused effort can plausibly move your standing. Plausibly, not certainly. The benchmark I run tracks exactly this kind of movement over time.
The honest caveat
This is 6 queries from one run across two engines, captured on a single date. The counts are small, the sample is narrow, and AI engines change their behavior by prompt, model, and week. A domain at 4 citations today could sit at 2 next month, and a vendor absent here could surface tomorrow. So read this as a directional snapshot, not a leaderboard. The pattern, vendor pages leading and a flat field, is the part I would trust more than any single number.
No one can guarantee a citation inside systems they do not control. The realistic work is to improve your odds of being the cited answer over time, which is the whole point of AI search optimization and the benchmark behind this post.

FAQ
Which sources does AI cite most for helpdesk software? In this sample of 6 queries across Perplexity and ChatGPT, Freshworks, Zoho, Help Scout, and Zendesk led with 4 citations each, followed by Plain, LiveAgent, Intercom, TechRadar, and HubSpot at 3 each. Vendor pages led over review sites. Results vary by engine, prompt, and date.
How many citations did the helpdesk sample contain? The category drew 56 citations across 6 queries, spread over 31 distinct domains, roughly 9 per query with a flat distribution. Treat it as a small directional sample.
Do AI engines cite vendor sites or review sites for helpdesk software? Both appeared, but vendor-owned domains led, with TechRadar the only pure publisher in the top tier. A vendor benefits from being strong on its own pages and on review media.
Can a helpdesk vendor guarantee an AI citation? No. These systems are not controllable and the sample is small and time-bound. The goal is to improve your odds over time through entity clarity, strong vendor pages, and review-media presence.
