AI Answers Cited Vendors' Own Websites in Up to 97% of B2B Buying Questions

Robauto Team · Published Nov 9, 2026 · Last updated Nov 9, 2026

Two November 2026 studies show AI assistants lean on vendors' own pages for B2B questions, citing them in 88-97% of answers. Here's how brands can turn clear, checkable facts into AI citations.

Here is some genuinely good news for any company that sells to other businesses: when buyers ask AI assistants for help choosing a vendor, the answers lean on vendors' own websites more than on anything else. A study published on November 5, 2026 by Hasmord found that 88% to 97% of B2B answers cited at least one vendor's own site, depending on the engine. That means the pages you already control can become the evidence an AI uses to describe you.

What the November 2026 study measured

Hasmord asked 60 B2B buying questions, from "best CRM for small business" to "how to choose a PCB manufacturer," three times on November 5, 2026 in Google AI Overviews, ChatGPT and Perplexity. It then sorted every cited site by type: vendor sites, review platforms, media, independent blogs, directories, forums and video. The questions covered 12 categories, six in software and six in suppliers and sourcing, with five questions each (source).

The headline is simple. Vendors were the main source in every engine. Google AI Overviews cited a vendor's own site in 89% of answers, ChatGPT in 88% and Perplexity in 97%. For comparison, the same team's October shopping study found brand sites cited in only 50% to 57% of consumer shopping answers.

Why this is an opportunity, not a threat

For years, many businesses assumed that AI answers would mostly repeat what big publishers and review sites said. For B2B buying questions, this data points the other way. Media and publishers showed up in only 31% to 57% of B2B answers, while vendor pages appeared in nearly all of them. When a buyer asks about pricing logic, integrations, certifications or lead times, the clearest page on the web is often the vendor's own, and the engines seem to know it.

Several categories were especially strong. In the pooled results, CRM software, HR and payroll, and logistics and 3PL answers cited a vendor site 100% of the time, and contract manufacturing and packaging suppliers were at 98% and 97% (source). Hasmord notes these rest on five questions per category, so they are directions rather than precise rates.

Comparison pages get read

One of the more practical findings: AI engines read the comparisons vendors write. By title, 518 of 979 vendor citations in Perplexity and 253 of 548 in Google AI Overviews were a vendor's own "best tools" list or head-to-head comparison. On "X vs Y" questions, ChatGPT cited both companies' own sites in 25 of 36 answers (source). That is a strong signal that ChatGPT goes to the source when it can, which rewards companies that publish honest, checkable facts about themselves.

A second study agrees on the shortlist

A separate study from Babel42, published November 4, 2026, asked five AI assistants the same 257 questions in 10 industries once a day from November 1 to 3. It found that the assistants pick very different sources but mostly agree on which brands to recommend. When all five named brands for the same buying question on the same day, they had at least one brand in common 77% of the time.

Babel42 also found that brand recommendations came with a citation to the brand's own site 15% of the time overall, but the business categories did best. HR and recruiting brands had their own site cited in 23.5% of recommendations, business software in 23.3% and legal services in 21.7%, compared with single digits for most consumer categories (source). The two studies measure different things, but they point the same way: in business categories, your own pages carry real weight.

Each engine still has its own taste

Both studies show that engines behave differently. Hasmord found 77% of Google AI Overviews cited a video, almost all on YouTube, and 64% cited a forum or social site, while ChatGPT and Perplexity cited forums in only 4% and 5% of B2B answers. Babel42 found ChatGPT cites about 1.8 sites per answer, while Perplexity cites 8.6, so a ChatGPT citation slot is scarce and worth earning (source).

Citations also move over time. When Hasmord re-ran its 60 shopping questions two weeks later, Perplexity cited 62% of the same sites, Google AI Overviews 57% and ChatGPT 37% (source). That is encouraging for newcomers: the field is not locked, and a company that improves its pages this month can show up in answers next month.

The Robauto takeaway: make your facts easy for agents to use

If AI answers already treat your website as a primary source, the job is to make that source clear, complete and easy for agents to read. Here is a practical checklist for brands:

• State the facts plainly. Put pricing logic, plan limits, integrations, certifications, service areas and lead times on real HTML pages, not only in PDFs or behind forms.

• Publish an honest comparison page. Engines read vendor-written comparisons. Write your own with facts a buyer can check, so you are not only described by a competitor's list.

• Cover Google's preferences too. AI Overviews lean on YouTube and forums, so a short product walkthrough video and helpful community answers can complement your site.

• Keep policies and contact details current. Refund, support and contact pages are exactly the details buyers and their agents ask about.

• Measure over weeks, not once. Both studies show citations change day to day and week to week, so track trends.
