The Most Cited Websites in LLMs (and How to Get Your Brand Mentioned on Them)

Large language models do not return ten blue links. They read a handful of pages, blend them with what they already know, and hand back a single answer with a few citations attached. If your brand is not in that small set of trusted sources, you are invisible at the exact moment a buyer is asking ChatGPT, Gemini, or Perplexity for a recommendation. This guide covers which websites those models lean on, why a mention there works as a trust signal, and the realistic ways to get exposure on each one.

Before the tactics, three things that are easy to get wrong and expensive to ignore.

First, there is no single “most cited website,” and anyone who gives you one number is hiding the methodology. Depending on the engine and the study, the leader is either Reddit or Wikipedia. In Ahrefs’ June 2026 Gemini dataset, Reddit captured roughly 27.5% of mention share. In Similarweb’s January to February 2026 ChatGPT data, Wikipedia led at about 13.2% with Reddit just behind at 12%. An older Semrush sample put Reddit at around 40% and Wikipedia at 26%. These percentages are not comparable, because each study uses a different denominator, time window, and engine. Treat them as direction, not gospel.

Second, citation is a long tail, not a winner-take-all market. Contently, summarizing an Evertune analysis of 200 million prompts, found that even the top domain on any platform rarely clears 5% of total citations, and the rest spreads across thousands of sites. That is the opposite of classic search, where the top ten results capture roughly two thirds of clicks. The implication is good news: you do not need to beat Wikipedia, you need to be present in your category’s slice of the tail.

Third, a meaningful chunk of the most-cited domains cannot be acquired through marketing at all. Wikipedia, government and medical sources, and peer-reviewed journals are cited heavily and are off limits to outreach. Knowing which doors are open saves you from burning effort on doors that are bolted shut.

Which websites do LLMs cite most?

Across every large study, the same small core shows up: Reddit, Wikipedia, YouTube, LinkedIn, and a rotating cast of major publishers. The interesting part is how sharply the picture changes by engine.

• ChatGPT leans on encyclopedic and community sources first. Similarweb’s data has Wikipedia and Reddit far ahead of everything else, with one surprise in third place: OpenAI.com itself at about 6.2%. ChatGPT cites its own publisher, which quietly shapes which narratives about AI get amplified. Ahrefs’ separate analysis of 9.6 million ChatGPT queries puts Reddit and Wikipedia on top, followed by Amazon, Forbes, and Business Insider.
• Google AI Mode tells a different story. In Similarweb’s data the number one source is not Wikipedia or Reddit, it is Fandom.com at about 7.2%, ahead of Wikipedia, YouTube, and Reddit. There is a structural reason, covered below.
• Gemini, per Ahrefs, is led by Reddit (27.5%), YouTube (13.7%), and Wikipedia (12.7%), then leans hard into commerce and vertical review sites for product and how-to queries.
• Perplexity, in Semrush and Peec data, favors Reddit, LinkedIn, YouTube, Wikipedia, and B2B review sites such as G2.

Goodie’s analysis of 58.6 million citations between October 2025 and March 2026 captured how fast this moves: 13 of the top 20 domains turned over in roughly six months, with gaming and review sites displacing the news publishers that had dominated. The takeaway is to track citation share like you track rankings, not to memorize a list.

Why a mention there is a trust signal

The reason exposure on these platforms matters is mechanical, not vague. When a model has seen your brand discussed on Reddit, referenced on LinkedIn, and covered on a review site, it has already formed a view of your credibility before any user asks about you. Brand mentions are entity signals, and the models weight them.

The compounding is real. Goodie, citing Ahrefs correlation data, reports that brands in the top quartile for web mentions receive more than ten times the AI Overview citations of those in the next quartile down, and that gap widens over time because more citations signal more authority, which produces more citations. Goodie also found that roughly 74% of the most-cited LLM domains are ones marketing can directly influence, which is the size of the opening.

Two more findings reinforce why this is its own discipline, separate from traditional SEO. Ahrefs found that only about 12% of AI citations overlap with Google’s top ten results, so ranking and being cited are different games. And BuzzStream found that around 75% of sites that block AI crawlers still appeared in citations, with roughly 95% of cited pages blocking the training bots GPTBot or Google-Extended. Blocking a training crawler does not protect you from, or guarantee you, live citation. The one concrete live-crawler block worth knowing is that Facebook blocks Perplexity’s bot.

How to get exposure: the four ways onto these platforms

Every cited domain falls into one of four acquisition modes. The spreadsheet below sorts 88 of them accordingly, with the specific method, the link type, the Ahrefs Domain Rating, the estimated monthly organic traffic, and notes. Download it and work it category by category.

1. Fully self-serve

You create the account or content directly, today, for free. Reddit, LinkedIn, YouTube, Medium, Quora, X, Facebook, Instagram, GitHub, wikiHow, and Fandom. All nofollow, all valuable as mentions. The catch on Reddit and the wikis is that overt self-promotion gets removed, so you have to add real value rather than drop links.

2. Earn editorial

You cannot self-publish; you pitch, get quoted, or place a product. This covers the tech reviewers (TechRadar, CNET, PCMag, Tom’s Guide), the news desks (Reuters, Business Insider, the major nationals), lifestyle and beauty titles, the auto data sites, and the finance editorial set. Use journalist-sourcing services and digital PR. Link type varies by outlet and section, so confirm per placement rather than assuming.

3. Paid distribution

PR Newswire, which earns brand mentions and wide syndication and shows up in ChatGPT citations, and Forbes via its paid routes. Forbes closed open contributor applications in 2024 and culled contributors again in December 2025; the paid paths now are Forbes Councils, an eligibility-gated membership of roughly 2,000 to 2,500 dollars a year, and BrandVoice sponsored content, which is disclosed as advertising.

4. Not acquirable through marketing

Do not spend outreach budget here. Wikipedia is notability-gated; you cannot legitimately create or buy your own page, you earn the notability and let independent editors decide. Government, institutional, and peer-reviewed sources (NIH, PubMed Central, Nature, Science) come only from publishing or institutional standing. ArXiv and GeeksforGeeks are the two semi-open exceptions for researchers and contributors.

Do not skip your industry-specific platforms

The general list is the head of the distribution. The leverage is usually in your category, where a single niche platform can outweigh Reddit. The numbers from Goodie’s vertical breakdowns make the case:

• B2B SaaS (CRM and sales): TechRadar commands about 8.9% citation share, the single highest category figure in the study, with G2, Capterra, and Monday.com close behind.
• Consumer electronics (wearables): Vertu holds roughly 15.6%, the highest single-domain figure in any category measured.
• Hotels and resorts: Wikipedia leads at about 10.4%, but Peec found Booking.com and Airbnb outrank Reddit as AI sources in this space.
• Retail banking and fintech: NerdWallet is the clear leader, ahead of Forbes and Yahoo Finance, with Bankrate and Investopedia as reference anchors.
• Skincare and cosmetics: Wikipedia leads narrowly, but a single brand, Kaja Beauty, sits second ahead of Alibaba and Instagram.
• Automotive: Gemini leans on Edmunds, Kelley Blue Book, and Car and Driver, which barely register on the general list.

The method is simple: run your real category prompts through the engines your buyers use, log which domains get cited, and treat that list as your target set. A review platform or trade title that dominates your niche is a higher-return placement than any generic top-ten site.

What gets cited: the Fandom lesson

The most useful single insight in the data is why Fandom outranks Wikipedia in Google AI Mode. It is not only that AI Mode sees a lot of entertainment queries. Fandom pages are built the way AI retrieval rewards: long, single-topic pages, organized under precise headings, each one existing to answer one specific question about one specific thing. Similarweb’s data also shows AI rarely cites homepages; it pulls from pages several folders deep, the FAQs, the how-to guides, the detailed product and research pages. BuzzStream found that blog and long-form content made up about 53% of all AI citations, far ahead of news at 14% and social at 9%.

Translated into a content rule: depth on a specific topic beats breadth every time. A well-structured product or guide page can be cited above a giant retailer for a niche question, the same way Fandom is cited above Wikipedia for a niche one.

A 90-day starting point

• Claim and complete every self-serve profile that fits your category, and start posting from named senior people on LinkedIn weekly.
• Participate authentically in the two or three subreddits and forums where your buyers already are. Do not drop links.
• Solicit structured reviews on the review platforms your category trusts (G2, Trustpilot, or the niche equivalent).
• Pitch one earned editorial mention per month in a category-relevant publication.
• Publish deep, single-topic pages and original data on your own site, structured for extraction.
• Track citation share monthly, the way you track rankings, and adjust toward what moves.
