Who Writes the "Best" Lists AI Reads? A Check of 16 B2B Fields

By Mehmet, Top Seed AI · Published Nov 1, 2026

In short: Mostly the companies on them. On November 1, 2026 we searched "best [service] 2026" in 16 B2B service fields and read the first eight results. Of 94 distinct list pages, 62 (66%) were written by a company that sells that service and puts itself on its own list, and 57 of those 62 put themselves first. About one in three said so plainly. We sell AI visibility work, including pages like these, so we have an interest in the topic; the method and every example are below so you can check our reading.

Why we looked

When an AI assistant searches the web to answer "who should we hire for X?", it pulls in pages from the results, and "best X" lists are built to answer exactly that question. One published analysis of about 20,000 Microsoft Copilot citations for a single website found that a detailed comparison page took most of them (Search Influence). That is one site, not a rule.

So we asked a simpler question: who writes these pages? This study does not measure which pages any AI assistant cites. It measures who wrote the pages a web search returns for typical "who to hire" searches.

How we checked

• Fields: 16 B2B services where buyers choose a provider, from SOC 2 audits and penetration testing to HubSpot agencies, 3PLs and fractional CFOs (full list in the table below).
• Search: one search per field, worded "best [service] 2026", run on November 1, 2026 with the web search tool we use for research. We took the first eight results in order.
• Reading: we opened every page and noted who publishes it and whether the publisher appears on its own list. For self-listing pages we recorded the publisher's position and whether the page says plainly that the publisher is on the list.
• Categories: a list by a company that sells the same service and includes itself; a list by such a company that leaves itself out; a list by a company that sells something adjacent, such as software; an independent directory or review site; media or a blog; and pages that are not lists at all.
• Duplicates: 21 results were the same article under another address (short links, redirects, translations, AMP copies). We counted each article once, which leaves 107 distinct results, of which 94 were lists.

What we found

Four patterns stood out.

• They put themselves first. 57 of the 62 self-listing pages ranked the publisher first or listed it first. The other five placed it second, third or sixth.
• No vendor left itself out. We found no list written by a company in the field that did not include that company.
• Most do not say so. About 20 of the 62 (32%) state plainly that the publisher is on the list. Some are direct: "Full disclosure: we're one of the ten, and we put ourselves first." (Waveup); "Yes, Orange Marketing is on here. We're biased" (Orange Marketing). Others say "This Is Not a Ranked List" while placing themselves first (Bright Defense).
• The exceptions are telling. In managed IT and PEO, most results were guides or lists written by software companies selling something else. In small-business cybersecurity, most results ranked software products, not service firms.

Pages that do not list themselves are not automatically independent. Two directories in our sample label paid placements (SOC2Auditors.org marks sponsored firms; Clutch says it may earn a fee for some placements), and a few media lists had partnership or referral tags on their top links. We could not confirm any undisclosed payment, so we counted those pages as independent.

What this means if you are buying

A "best" list tells you who exists in a field. It rarely tells you who is best, because the author usually sells the service. Before you rely on one, check:

1. Who publishes it? Look at the domain and the About page. If the publisher sells the service, expect it near the top.
2. Does it say so? A plain disclosure is a good sign; "independent ranking" written by a competitor is not.
3. Can you check the claims? Prices, client counts and awards should link to a source you can open.
4. Is placement paid? Directories should label sponsored entries.

Then ask the same question in two or three AI assistants and see which firms keep coming up, and which pages they cite.

What this means if you sell a B2B service

If buyers in your field search for "best [your service]", the pages they and AI assistants find are probably written by your competitors. If you are on none of them, you are likely missing from the material an assistant has in front of it when it answers.

Two honest responses are open to any field:

• Publish your own comparison page, and disclose it. Describe each firm fairly, link every fact to a source, say clearly that you publish the page and appear on it, and include a line on when you are not the best fit. We did this ourselves in Best AEO and GEO Agencies for B2B Companies.
• Get onto the lists that already exist. Directories and independent lists in your field are often open to accurate profiles, and reviews from real clients help.

What we would not do: write a list that pretends to be independent, invent rankings or reviews, or present paid placements as editorial picks.

Limits

• One search tool, one day, one wording. Results from Google, Bing or the search behind any particular assistant will differ, and the wording "best ... 2026" favors exactly the kind of list vendors write.
• Eight results per field, 16 fields. Mostly agency, consulting and IT services. This is a one-time check, not a representative sample of B2B services.
• Judgment calls. Deciding what counts as "the same service" (for example a staffing firm that places fractional CFOs) is a judgment. If we move the five closest calls out of the self-listing group, the share falls from 66% to 61%.
• Quotes. Pages were read with an automated reader that can paraphrase slightly. Examples from half the fields were checked against downloaded copies, and the quotes on this page were re-checked on the live pages.
• No citation data. We did not measure how often any assistant cites these pages.

Questions people ask

Do AI assistants actually cite "best" lists?

They can, when they search the web for "who should I hire" questions, but this study does not measure how often. A published analysis of one website's Copilot citations found most went to a single detailed comparison page (Search Influence). To check your own field, ask a buyer question in an assistant that shows its sources, such as Perplexity, and open the pages it lists.

Should my company publish its own "best" list?

It can, if it is honest. Say clearly that you publish the page and appear on it, describe competitors fairly with sources, and include when you are not the best fit. A list that hides who wrote it can mislead buyers and damage trust once they notice.

Are directories like Clutch or G2 independent?

They are not written by a competitor, which helps, but several sell visibility. In our sample, SOC2Auditors.org labels sponsored placements, Clutch says it may earn a fee for some placements, and Software Advice says some vendors may pay it for traffic or leads. Look for the label before you treat an order as a ranking.

How can I tell who wrote a list?

Check the domain, the author's employer and the site's About page; see whether the publisher appears on its own list; and look for a disclosure line near the top. If the first entry is the publisher and there is no disclosure, read the list as advertising.
