B2B content marketing: what AI answers cite, question by question

Last updated November 6, 2026 · ~8 min read

The short answer: B2B content marketing is publishing content that helps business buyers decide, and today AI answers read it first. We checked 504 AI answers to 60 B2B buying questions. Vendors’ own sites were cited in 78% to 100% of them, but the page depended on the question: guides for “how to choose”, “best X” lists for “best X”, comparison pages for “X vs Y”, and review platforms and pricing pages for “is X worth it”. 78% of comparison-page citations went to a third company’s site.

What is B2B content marketing?

B2B content marketing is publishing content that helps business buyers understand a problem, compare options and make a decision, so that your company is the one they trust when they buy. The usual plan maps content to the stages of a long sale: articles and videos to get found, guides and case studies while buyers compare, demos and pricing when they decide.

That plan still holds, but who reads the content first has changed. Buyers now put their questions to ChatGPT, Perplexity and Google’s AI Overviews, and the answer cites a handful of pages. If one of them is yours, your content is part of the answer. So we looked at which pages those answers cite.

We asked 60 B2B buying questions, three times each, on November 5, 2026, from a US location: five questions in each of 12 categories, from CRM and payroll software to contract manufacturing and 3PL. Every category had the same five: two “best X for Y”, one “X vs Y”, one “is X worth it” and one “how to choose X”. 504 answers cited at least one source. The full study has the overall shares; this page breaks them down by the question.

Each question pulls a different kind of source

Share of answers that cited at least one site of each type, shown as Google AI Overviews / ChatGPT / Perplexity, all three runs pooled.

Two things stand out. Vendors’ own sites were cited at every stage, in 78% to 100% of answers. Review platforms such as G2, Capterra and Trustpilot were cited most at one stage: about half the “is X worth it” answers cited one, and not a single “how to choose” answer did.

Which vendor page gets cited

“Vendor’s own site” covers very different pages. We sorted every cited vendor page by its address and title. Google hides part of its citation links behind a redirect, so its column counts only the 398 of 548 vendor citations with a visible address.

Google and Perplexity cite the page that matches the question: a list for a list question, a comparison for a comparison. ChatGPT works differently. When it names a vendor it usually links the vendor’s homepage (366 of its 608 vendor links). By title, only 15% of its vendor links were lists or comparisons, against 55% for Perplexity and 46% for Google.

1. “How to choose” guides: the vendor explains the decision

Buyers early in a decision ask how to choose. Here the vendors had the field to themselves: 91% to 100% of answers cited a vendor’s site, and none cited a review platform. On Google and Perplexity, most of those pages were buying guides, checklists and “questions to ask” articles on vendors’ own sites.

This is the cheapest place to start. A clear guide to the criteria that matter in your category, with real numbers where you have them, competes mostly with other vendors’ guides. Media sites were cited in 9% to 33% of these answers; only Google added forums and videos.

2. “Best X” lists: often written by a vendor

For “best X for Y” questions, 73% of the vendor pages Perplexity cited and 52% of those Google cited were themselves “best X” lists, such as “16 best CRMs for small businesses” on a CRM company’s blog. Media sites were cited too, in 35% to 79% of these answers depending on the engine. So a buyer asking for the best tool often gets an answer built partly on a list that one of the competitors wrote.

If you publish one, make it useful to a reader who may not pick you: name the real options and say who each one suits. That is also the kind of claim an answer can repeat.

3. Comparison pages: mostly written by someone else

On “X vs Y” questions, Google and Perplexity cited a comparison page for 98% of their vendor citations. Then we checked who published those pages. Across the three engines, of 321 comparison-page citations, 250 (78%) were on the site of a company that was neither X nor Y: a competitor, a partner or a consultancy. By page, 102 of the 121 comparison pages cited came from a third company.

Two examples. On “protolabs vs xometry”, Perplexity and Google cited a comparison by Jiga, another manufacturing platform, in all three runs. On “shipbob vs shipmonk”, ChatGPT and Perplexity cited one by Red Stag Fulfillment, another 3PL, in all three runs. If buyers compare you with a rival and neither of you has published the comparison, a third company’s page may be the one that describes you.

4. “Is X worth it”: reviews and prices

This is the stage where third parties count most. Review platforms were cited in 50% to 58% of these answers, against 11% to 21% for “best X” questions and none for “how to choose”. Google also cited a forum or social post in 75%. Among vendor pages, the most common on Google and Perplexity were articles answering the question (58% and 42%), and ChatGPT cited a pricing page for 14 of its 30 vendor links.

So the content you publish yourself is not enough here. A pricing page with real numbers and what each plan includes, plus reviews on the platforms buyers read, is what this stage drew on.

Two format details: video and dates

• Video, for Google only. Google’s AI Overviews cited a video, almost always on YouTube, in 69% to 86% of answers, depending on the question. ChatGPT and Perplexity cited no video in any run.
• Dates in titles. 21% of the page titles Google and ChatGPT cited contained “2026”, and 38% of Perplexity’s. Only 0.4% to 2% said 2025. We can’t tell from outside whether those pages were really updated, and the date in a title is not proof of anything. But titles dated last year were rare.

A B2B content marketing plan built from this

1. Write the “how to choose” guide for your category. The criteria, the questions to ask and the usual mistakes. Vendors were nearly the only source cited for these questions.
2. Publish comparisons for the pairs buyers ask about, starting with you against each main competitor. Keep them to facts a reader can check, such as prices, limits and integrations.
3. If you write a “best X for Y” list, make it fair. Name the real options, say who each one suits, and say where you fit.
4. Put real numbers on your pricing page. What each plan costs and includes, so the answer to “is it worth it” has something to work with.
5. Ask customers for reviews on the review platforms your buyers use. They mattered most at the stage closest to a decision.
6. Make your homepage say what you sell and to whom. It is what ChatGPT linked most when it named a vendor.
7. Add short videos for your main questions if Google matters to you.
8. Keep pages current, and change the year in a title only when the content changed too.
9. Check the answers over weeks. Ask your buyers’ questions in each engine and see which pages get cited. Sources change: when we asked our shopping questions again two weeks later, ChatGPT cited 37% of the same sites and Perplexity 62%.

Method and limits

60 B2B buying questions we wrote, 5 in each of 12 categories (six software, six supplier and sourcing), each asked three times on November 5, 2026, 10 to 20 minutes apart, from a US location: Google with the AI Overview loaded, ChatGPT through chatgpt.com search and Perplexity through its Sonar API, all collected through DataForSEO. A site counts once per answer, and percentages use answers that cited at least one source (Google 168, ChatGPT 156, Perplexity 180). Site types were assigned by one person, by domain and title; any company selling in these categories counts as a vendor, including consultants. Vendor pages were sorted by URL path and title with fixed word rules, so some pages land in the wrong group. Google’s hidden links have no address, so its page types use the 398 vendor citations with one, and the comparison count types the hidden ones by title. With five questions per category and one day, read the shares as directions, not rates. The raw rows are on the study page.

Where Hasmord fits

Hasmord is the AEO-native sales platform. Buyers ask questions across AI assistants, search, and sales conversations. Hasmord uncovers where your answers about your products and services fall short, turns evidence into better answers, finds potential customers for you, and connects every lead to your sales process.

In Hasmord, this is the first step, which uncovers where your answers about your products and services fall short. AI answers asks ChatGPT, Claude, Gemini and Perplexity your buyers’ questions and keeps every answer and the pages it cites, engine by engine, so you can see whose guides, lists and comparisons describe you.

The second step turns evidence into better answers: Hasmord compares those answers with your product facts and prepares fixes, product by product, for your team to approve. Find customers then finds potential customers already looking for what you sell, with the reason each one fits; only the people you verify join your CRM, and Hasmord never contacts anyone for you. In the CRM, each lead keeps the question that brought it, so what buyers ask in sales becomes the next piece of content to write. See pricing.

Vendors’ own sites were cited in 78% to 100% of answers.

Should B2B companies publish comparison pages?

Our data says someone will. Of 321 comparison pages cited on “X vs Y” questions, 78% were on a third company’s site, not on either company being compared. Keep yours to facts a reader can check.

Do review sites matter for B2B content marketing?

Most at one stage. Review platforms were cited in 50% to 58% of “is X worth it” answers, 11% to 42% of “best X” and “X vs Y” answers, and in none of the “how to choose” answers.
