How AI assistants choose which sources to cite: what we know and what is guesswork

Is it worth your time to get quoted in news articles, and does that have anything to do with what AI tools say about your brand? This guide explains how expert quote requests work, looks at what studies actually show about the pages AI tools cite, says plainly what nobody knows yet, and covers the risks.
An expert quote puts your name next to a real answer on a page that a journalist, not you, decided to publish. That has value for the people who read it, and the evidence suggests news pages are one of several kinds of page AI tools draw on. No study we found shows that being quoted makes an AI tool more likely to name you, so treat that as unproven.
An expert quote is a short answer from someone who knows the subject, used inside an article the journalist is writing. The journalist asks a question, you answer it, and the journalist decides whether and how to use your words. You don't write the article, you don't control where it appears, and you can't buy a place in it.
That's what separates it from a guest post (which you write and the site publishes) or a paid sponsored article (which is advertising). It also explains why quotes are hard to earn: the journalist is the gatekeeper, and a bad answer gets ignored.
For a brand, the value is plain even without AI in the picture. A reader sees your name next to a useful answer on a site they already trust. The page may link to you, and it may not. And the page exists on the web afterward, where search engines, readers and AI tools can all find it.
Journalists who need sources post queries. Experts see them, send answers, and the journalist picks what to use. Several services run this kind of exchange. One long-running example is Help a Reporter Out (HARO), which Featured.com took over from Cision in April 2025. Its announcement says HARO "will remain free for journalists and sources, supported by newsletter ads," and delivers daily opportunities by email.
A few facts about the process, which hold whichever service you use:
If your goal is to be named in AI answers, you want to know which kinds of pages those tools draw on. Here's what we could read, with each study's size and date. Muck Rack, Semrush and Profound all sell related software, which is a reason to read their studies with care.
Pew's July 2025 study tracked 900 U.S. adults on an online panel and collected 68,879 unique Google searches from March 2025. Pew looked at the source links shown in Google's AI summaries (up to three source URLs per summary). The most common were Wikipedia, YouTube and Reddit, together 15% of the sources in AI summaries and 17% in standard results. News websites made up 5% of sources in both AI summaries and standard results. Pew found .gov sites at 6% of sources in AI summaries against 2% in standard results.
What it doesn't show: Google only, one month, and it counts source links, not how much each page shaped the answer.
Muck Rack, which sells PR software, analyzed more than 1 million links cited by ChatGPT, Gemini and Claude, collected in July 2025. It reported that 95% of the links were non-paid media, 89% were earned media and 27% were journalistic content. For prompts that implied recent news, 49% of cited links were journalistic. It also found that the most common age for a cited page was one day, and its own researcher called the data "a time capsule."
What it doesn't show: the pages we could read don't give the number of prompts or define "journalistic" in detail, and the prompts were Muck Rack's own.
Semrush analyzed more than 230,000 prompts on ChatGPT search, Google AI Mode and Perplexity from July 14 to October 12, 2025, covering over 100 million citations. Its finding that matters most here is how fast things change: ChatGPT's citations of Reddit and Wikipedia fell sharply in mid-September 2025, while Google AI Mode and Perplexity stayed fairly stable. Semrush says it can't tell why. News sites moved in different directions: Forbes and PR Newswire gained on ChatGPT after September, while TechRadar fell.
Profound analyzed 680 million citations across three AI platforms from August 2024 to June 2025. It found Wikipedia was 7.8% of all ChatGPT citations, and Reddit was 6.6% of Perplexity's. Both Semrush and Profound sell AI visibility tools.
Pew puts news sites at 5% of sources. Muck Rack puts journalistic content at 27% of links. Both can be right. They tested different tools, used different questions (Pew used real searches by volunteers; Muck Rack used prompts it designed), counted different things and defined "news" differently.

Our view: the takeaway isn't "news wins" or "news loses." It's that AI tools draw on many kinds of pages (reference sites, forums, video, news, brand sites), the mix depends on the tool and the question, and it changes quickly. A plan that depends on one page type is fragile.
Be careful here, because this is where overconfident advice shows up.
So if someone promises you AI citations from a quote, they're guessing. Google's own page on AI features says there are no additional requirements to appear in AI Overviews or AI Mode, and no special optimizations necessary.
Journalists skim. A reply that's easy to use gets used.

A reply can be as plain as the one below. The brackets are placeholders, and the question is invented.
Subject: Re: How can small online stores handle holiday returns?
Hi [Name],
Short answer: set the return window before the sale starts, not after. [Your one specific example from your own work, or a figure you can source.]
My background: I'm [role] at [company], and I've [what you actually did] for [how long]. I'm happy to be quoted by name and title.
If useful, I can answer follow-up questions today.
Thanks, [Name, title, company, phone, website]
Real expert quotes aren't paid. A paid article placement is different. If money changed hands, readers and regulators expect it to be clear. The U.S. Federal Trade Commission's native advertising guidance (December 2015) says an advertisement "shouldn't suggest or imply to consumers that it's anything other than an ad." Google's spam policies treat links that are bought or sold to pass ranking signals as link spam unless the link is marked rel="sponsored" or rel="nofollow", and some placements carry a label. See our post on link rel attributes.
Our view: a service that promises you a quote on a named site in exchange for money is selling something other than an expert quote, and you should ask how the placement will be labeled.
On topics such as health, money and law, Google says its systems give more weight to signs of trust. Our guide to YMYL and E-E-A-T explains what that means. Use real credentials, and don't give personal advice you aren't qualified to give.
Journalists can trim or rephrase what you send. And AI tools aren't reliable at tracing text back to its source. The Tow Center for Digital Journalism gave eight AI search tools 1,600 test queries in February 2025, each containing a quote from a news article, and asked for the headline, publisher, date and URL. More than 60% of answers were wrong, and tools often cited copies on aggregator sites such as Yahoo News or AOL rather than the original publisher. So even when a quote of yours appears in an AI answer, it may be credited to a copy of the article, or not credited at all.
An article may not link to you, or may link with a nofollow or sponsored attribute, or may be edited later. Judge each result as coverage first and a link second.
Is this route right for you?
Good fit
Poor fit
It's also a poor fit if you can't give a useful answer without selling something, if your topic is one that mainstream news sites rarely cover, or if you're hoping a single quote will move AI answers. Slow, steady, relevant coverage is the realistic goal.
