Directories Supply 41% of AI Citations on Supplier Prompts: What B2B SaaS Should Do Next
TL;DR
- On Sep. 15, 2026, Citations.press published a study of 3,850 supplier-selection prompts across ChatGPT, Google AI Mode, Perplexity, and Google AI Overviews.
- Sector directories supplied 41% of citations on those prompts, versus 18% for brand-owned pages. In engineering, directory citations outnumbered brand-site citations 4.2 to 1.
- 68% of directory citations came from list pages, not individual profiles. Directories with one entity per entry and consistent attributes were cited 3.1× more often than free-text listings.
- Read the conflict of interest: Citations.press also operates the sector directories used as the study’s test set. Treat the direction as useful, not as gospel without your own prompt panel.
- DerivateX’s take: this is further evidence that AI recommendation share for B2B is won off-site, on structured third-party lists, not by polishing the homepage alone.
Most B2B SaaS teams still treat “AI search” as a content rewrite problem on their own domain. A fresh supplier-selection study says the answer engines are often not reading your homepage when a buyer asks who to hire.
They are reading directories.
That is uncomfortable if your GEO program is mostly blog posts and a pricing page. It is also the opening for an operator stack that most agencies will not copy cleanly: map the lists that actually get cited, earn structured presence there, then prove it in CRM.
This piece is DerivateX’s read of the Sector Directories Are Driving AI Overview Citations study, what to trust, what to discount, and what to do this month.
What the study measured
Citations.press ran 3,850 commercial prompts between June 10 and August 22, 2026 across four surfaces:
- ChatGPT
- Google AI Mode
- Perplexity
- Google AI Overviews
The focus was supplier-selection style prompts (category and provider recommendation asks), not general informational queries. That matters. A “what is payroll software” answer and a “recommend a payroll platform for 200-person US SaaS” answer pull from different webs.
Headline findings from the published study:
| Finding | Number |
|---|---|
| Directory share of citations on supplier-selection prompts | 41% |
| Brand-owned page share on the same prompt set | 18% |
| Brand homepage appearances overall | 14% |
| Brand homepage appearances on category (not company-named) prompts | 6% |
| Engineering: directory citations vs brand-site citations | 4.2 to 1 |
| Directory citations from list pages (not profiles) | 68% |
| Structured one-entity entries vs free-text listings | 3.1× citation rate |
Citation rates for sector directories on category prompts, by surface:
- Perplexity: 47%
- Google AI Overviews: 39%
- Google AI Mode: 36%
- ChatGPT: 22%
The study also reported a weak relationship between a directory’s domain authority and citation rate (Spearman ρ = 0.19). Coverage depth inside a narrow sector predicted citation better than broad high-authority directories with shallow category pages.
Overlap between the cited source sets across the four platforms was only 31%. Same buyer intent, different “webs” per engine.
The conflict of interest you should say out loud
Citations.press is transparent that it publishes AI citation research and operates the sector directories used as the study’s test set.
That does not make the data useless. It does mean you should not treat “directories win” as a universal law proven on an independent sample of the entire web. It means:
- The directional claim matches a lot of other B2B citation research (review directories and lists show up heavily in commercial answers).
- You still need your own prompt panel on your category, your engines, and your competitors before you reallocate budget.
- Any vendor selling directory inventory will love this PDF. Your job is to verify whether your money queries cite G2, Clutch, niche listicles, Wikipedia, Reddit, trade press, or something else.
DerivateX’s first-party vs third-party citations and third-party assets for AI search pieces already argued that brand sites alone under-explain recommendation answers. This study is another datapoint in that direction, with the caveat above baked in.
Why brand sites lose on “recommend a provider” prompts
When a buyer names a company, brand pages get a fairer fight. When a buyer names a category, engines need a compact, comparable set of entities. List pages are built for that job.
That is why 68% of directory citations in the study came from list pages, not profile pages, and why structured attributes beat free-text blurbs.
It also lines up with DerivateX’s AI Overviews citation research: commercial software answers lean on third-party lists and formats that look like evidence, not brochure copy.
If your “AI content plan” is still “rewrite the homepage for ChatGPT,” you are optimizing the page that showed up in 6% of category-prompt responses in this dataset.
Operator playbook for B2B SaaS (this month)
1. Build a supplier-prompt panel, not a keyword list
Write 25 to 50 prompts a real buyer would ask an assistant:
- “Best [category] for [ICP / size / region]”
- “Alternatives to [competitor] for [use case]”
- “Recommend a [category] vendor that integrates with [stack]”
Run them logged out across ChatGPT, Perplexity, Claude, Gemini, AI Overviews, and AI Mode on a fixed cadence. Log named brands, linked sources, and whether you appear.
2. Inventory the list domains that actually cite (or should)
From the panel, pull every domain that powered a recommendation. Cluster them:
- Horizontal review platforms (G2, Capterra, Clutch, TrustRadius)
- Niche sector directories and partner finders
- Editorial roundups and “best of” listicles
- Community / UGC
Prioritize presence and accuracy on the short list that already appears, not every DR90 site on a media kit.
3. Prefer structured list presence over vanity profiles
The study’s strongest operational hint is structural: one entity per entry, consistent attributes, list pages that models can parse. For SaaS that usually means:
- Complete, current review-platform profiles with categories, integrations, and pricing signals that match your site
- Accurate listings on niche directories your buyers and partners already trust
- Editorial listicles where your differentiation is a real attribute, not a paid badge
4. Keep first-party pages as citation ammunition, not the whole war
You still need pages that third parties and models can quote: comparison pages, use-case pages, integration proof, methodology, and case studies. The point is sequencing. Off-site list presence without citable first-party proof is empty. First-party proof without off-site distribution often stays invisible on category prompts.
5. Tie it to pipeline, not “we got listed”
A directory mention that never shows in demos is a press clipping. Connect AI-influenced sessions and assisted opportunities in CRM the same way you would for any other channel. Gumlet is the public reminder that revenue attribution beats vanity visibility.
How DerivateX would brief a CMO after reading this
- Do not panic-buy every directory. Buy coverage where your prompt panel already shows engines reading.
- Do not kill brand content. Kill the fantasy that brand content alone wins category recommendation prompts.
- Measure recommendation share by engine. The study’s 31% source overlap is a warning: one ChatGPT screenshot is not a multi-engine strategy.
- Treat list pages as the unit of competition. Profiles matter. Ranked and structured lists matter more in this dataset.
- Say the conflict of interest in the board deck. Credibility compounds when you show you read the methodology footnote.

FAQ
What did the Citations.press directories study find?
On 3,850 supplier-selection prompts across four AI surfaces, sector directories accounted for 41% of citations versus 18% for brand-owned pages, with list pages driving most directory citations.
Does this mean my SaaS blog no longer matters?
No. It means category recommendation answers often pull from structured third-party lists. Your site still needs to be citable; it often will not be the primary shortlist source on “recommend a provider” prompts.
Why flag the conflict of interest?
Citations.press operates the directories used in the test set. Directional findings can still be useful, but you should validate on your own category and engines.
Which AI surface cited directories most in the study?
Perplexity (47% on category prompts), then Google AI Overviews (39%), Google AI Mode (36%), and ChatGPT (22%).
What should we do first this week?
Run a supplier-prompt panel, extract the list domains that appear, and fix structured presence on those domains before launching a broad “get on every directory” campaign.
How does this connect to DerivateX’s other research?
It reinforces first-party vs third-party citation dynamics and the off-site work described in third-party assets for AI search, with a fresh 2026 supplier-prompt datapoint.
