Do backlinks still matter for ChatGPT and AI search?

Your agency's monthly report says the number of sites linking to you is up again. The graph goes the right way. Then a prospect mentions that they asked ChatGPT for three firms like yours and you were not one of them. Your sales director asks the obvious question: if all those sites link to us, why has nobody noticed?

Backlinks still matter for AI search, but the count in your report is the wrong measure. In a study of 75,000 brands published by Ahrefs in May 2025, how often a brand was mentioned across the web correlated far more strongly with appearing in Google's AI Overviews (0.664) than the number of backlinks did (0.218). Links help assistants find and trust your pages. What other trusted sites say about you, in words, does more.

This guide explains where links still fit, which sites that link to you or mention you count, and how to audit what you have in an afternoon, with free tools if you do not pay for an SEO platform.

#Do backlinks still matter for ChatGPT visibility in 2026?

Yes. Links remain one of the ways search engines judge which pages to trust, and most AI assistants start from a search index. An SE Ranking study reported in November 2025 found the number of referring domains was the strongest predictor of whether ChatGPT cited a page.

Google AI Overviews and AI Mode use Google's index; Copilot uses Bing's, and ChatGPT search has drawn on Bing. So ranking helps, but it does not guarantee a mention. Ahrefs found in March 2026 that only 38% of AI Overview citations came from pages ranking in the top ten, down from 76% in July 2025, because Google now runs several related searches for one question. Links get your pages into the running; covering the follow-up questions and being described well by others gets you chosen.

#Are brand mentions more important than backlinks for AI search?

On the evidence so far, yes. The Ahrefs study of 75,000 brands measured how strongly different signals correlated with a brand appearing in AI Overviews:

Two cautions. Correlation is not cause, and the study covered Google's AI Overviews in 2025, not every assistant. But the direction fits how these systems work: they read text. A trade article that describes your firm in a full sentence teaches an assistant what you do, with or without a link. The best coverage gives you both.

#What jobs does a link do for AI search?

Three separate ones, and it helps to keep them apart because they lead to different decisions.

• It records someone else's judgement. An editorial link, one a journalist or editor chose to include, shows that someone with a reputation to protect thought your firm worth pointing readers to. That is the corroboration assistants look for.
• It helps your pages get found in live search. When an assistant searches the web to answer a buyer's question, well-linked pages are more likely to be among those it reads. A service page with nothing pointing to it may never be fetched.
• It ties the mention to you. A link makes clear which firm is being discussed, which matters if your name is close to another business's or your trading name differs from your registered one.

That last job has limits. A link or a redirect does not explain how two names relate. With ID-Pal, which had bought NorthRow: "The redirect from northrow.com was technically correct, but nothing on either site told Google or the AI engines that NorthRow and ID-Pal were the same company." The fix: "About four hours of structured data work declaring NorthRow part of ID-Pal on both domains." The result we track: "AI answers still recommending NorthRow as a rival: six in May, one in September 2026." (ID-Pal case study). Links point; words and markup explain.

#What is a referring domain, and why does the count mislead?

A referring domain is a separate website that links to yours at least once. If a trade magazine links to you ten times, that is still one referring domain. SEO tools count them because the number is easy to measure and tends to rise.

The count treats every site the same. A free directory listing nobody visits adds as much to the total as a feature in the magazine your buyers read. An agency paid to grow the number will go after the cheap ones. The score most agencies quote alongside the count is explained in what domain authority is and whether AI assistants use it.

For example, two management consultancies might each have about 200 referring domains. The first has mostly directory listings and a press release copied onto a hundred news-wire sites. The second has fewer links, but they include two trade press features, an entry on its professional body's register and a quote in a regional business paper. On the report they look level. The second is the one an assistant has read about in a context that explains what it does.

#Which sites that link to you or mention you count most?

Those with real editors, real readers and a record in your field, plus the community and review sites assistants cite heavily. No assistant publishes a list, but in our experience the order below holds.

Tier four is the one most link reports miss. In Google's AI Overviews, Ahrefs found YouTube (22.9%) and Reddit (18.5%) had the largest shares of mentions among the most-cited sites in the US. A Semrush study in March 2026 found LinkedIn in about 11% of AI answers. And in G2's April 2026 survey of 1,076 software buyers, 45% said citations of review sites were the most confidence-inspiring signal in an AI answer. For a B2B firm, that means your founder's LinkedIn articles, honest client reviews on the platforms your buyers use, and being discussed accurately where your buyers talk.

Tier five is not worthless. For "best firm" questions, assistants do cite curated directories, review platforms and ranked lists: a Peec AI study reported by Search Engine Land found review sites such as G2 common in recommendation answers. Keep accurate entries on the handful of curated directories in your sector. The long tail of generic directories adds little.

#Why does an editor's choice count for more than a listing you submitted?

Because someone who answers to their readers made a judgement. An editorial link sits inside written content, in a sentence about what you do. A submitted link sits in a list, in the same template as thousands of other firms. It proves you exist, not that anyone thinks well of you.

For example, a recruitment agency sends a press release about a new office through a wire service, and it appears word for word on a hundred small news sites. The same week, a trade editor quotes its founder on hiring shortages and links to its salary guide. The hundred copies add a hundred to the count. The trade piece is what tells an assistant what the agency is known for. Treat press releases as a way to reach journalists; the article a journalist writes because of one is what counts.

#Why do the words around a mention matter?

Because assistants learn from the sentence, not just the link.

• The topic of the page. A piece on cyber security for law firms that mentions a managed IT provider tells an assistant which category that provider belongs in. The same provider in a lifestyle blog's list of apps teaches almost nothing.
• How you are described. "Example Ltd, which handles employment disputes for hospitality groups" teaches something specific. "Other firms include Example Ltd" does not. If every link to you uses the same keyword phrase as its anchor text, it looks placed rather than earned.
• How much is said. A case study that spends several paragraphs on your work gives an assistant far more than a roundup of twenty names.
• Whether sources agree. Use one plain description of what you do, who for and where, everywhere you control, so earned coverage repeats it. When sources conflict, assistants hedge, as covered in why ChatGPT sounds unsure about our firm.

#Does it matter when and how quickly links arrive?

Yes. Assistants that search the web live find this year's coverage more readily than old pieces, and buyers read dates. A steady run of good mentions over a year looks like a firm people keep writing about; a burst of dozens of links in one week looks like a purchase. Repeat coverage from the same trade title is a good sign: a sector editor who quotes you three times a year is telling readers you are a regular voice. Why that steady rhythm matters is set out in how long PR takes to work.

#How do we audit the sites that link to us?

A useful first pass takes an afternoon. You do not need a paid tool.

#Step 1: Export the sites that link to you

With Ahrefs, Semrush or Moz, export every referring domain. Without one, use the free Links report in Google Search Console, which shows top linking sites, top linked pages and top linking text; Google notes it is a sample, with tables limited to 1,000 rows. Bing Webmaster Tools, also free, lists sites linking to you too, and Bing's index feeds Copilot.

#Step 2: Sort each site into the six tiers

Mark each as national press, trade or professional, smaller editorial, community or review, directory or wire, or harmful. Most firms find the bulk in tier five. That is normal, and it tells you what the headline number is made of.

#Step 3: Find the mentions that carry no link

Search for your firm's name in quotation marks, excluding your own site, and set up a free alert such as Google Alerts for your firm and founder names. Add anything in tiers one to four to your list, with or without a link.

#Step 4: Read the best mentions properly

Open the pages in tiers one to four and read what they say. Is the description accurate, current and in the right category? Note any old article about a service you no longer offer, because assistants may repeat it.

#Step 5: Compare with the competitors ChatGPT names

Ask ChatGPT, Gemini, Copilot and Claude the question your buyers ask and note who is named. Perplexity and ChatGPT search show their sources: list the trade titles, bodies and review platforms that mention those competitors and not you. That gap is your target list.

#Should we stop paying for link building?

Stop paying for links; keep paying for work that earns coverage. Google's spam policies treat buying or selling links that pass ranking credit as link spam, including paid articles and press releases with optimised anchor text. Link packages, paid guest-post networks and mass directory submissions add to the count without adding to the evidence.

Work that earns mentions is different: expert comment, original research, bylined articles, speaking and client case studies. Ask any provider what it will earn, where, and how it will report it. The routes are compared in digital PR or traditional PR for a B2B firm and which kinds of PR win work.

#What to do this month

1. Export your linking sites from Search Console or your SEO tool and sort them into the six tiers.
2. Set up alerts for your firm and founder names, and list unlinked mentions worth keeping accurate.
3. Put the question your buyers ask to the main assistants, note who is named, and list the sources that mention them and not you.
4. Pause spending on directory submissions, wire distribution or guest-post packages until you know what they have delivered.
5. Pick the two trade titles your buyers read most and find out who edits the sections your firm would fit.

#Frequently asked questions

#How many referring domains does a B2B website need?

There is no fixed number, and anyone who quotes one is guessing. It depends on how crowded your category is and how well your competitors are covered. Compare your tiers one to four with those of the firms being named, not with a target figure.

#How do I find unlinked mentions of my company online?

Search for your firm's name in quotation marks while excluding your own domain, set up free alerts for your firm and founder names, and check the sources assistants cite when they answer your buyers' questions. Paid mention trackers do the same at scale. If a journalist mentioned you without a link, a polite request is reasonable, but the mention is already doing much of the work.

#Are any directories worth being listed in?

Yes, a few. Registers kept by your regulator or professional body, the recognised directories in your sector, such as Legal 500 or Chambers for law firms, and well-used review platforms carry weight because they are curated or verified. Keep those entries accurate and consistent.

#Should we remove low-quality links pointing at our site?

Usually not. Google says most sites will not need to use its disavow tool, because in most cases it can assess which links to trust. The exception is links you or a previous agency paid for or arranged at scale; take advice before acting.

#Do links from our own other websites count?

Very little. Links from sites you own, such as a sister company or an old microsite, do not show that anyone else vouches for you. A case study on a client's website, in their own words, is worth more than a dozen links from your own properties.

#Can we just tell ChatGPT to correct what it says about us?

Not in any lasting way. Correcting it in your own chat does not change what the model has learned or what other people see. Change the sources it reads; answers based on live search usually update within weeks, and the model's own knowledge follows when it is retrained, which takes months.

If you would rather have someone run this audit and then earn the coverage that closes the gap, that is what Reputation That Wins is for. We start with the firms ChatGPT names instead of you and work back from there. The free Growth Review is a quicker first look.
