Each AI Engine Has a Favourite Type of Source: How to Become One

When someone asks ChatGPT, Google's AI answers or Perplexity to recommend a business like yours, the tool does not pluck a name out of thin air. It reads the web first, then writes its answer from a handful of sources it trusts. Get into those sources and you get into the answer. Stay out of them and you are invisible, no matter how good your website is.

The three big engines do not trust the same sources. They have genuinely different habits. ChatGPT reaches for encyclopaedic, authoritative pages. Google's AI Overviews lean on community and video. Perplexity is built almost entirely on one community site. If you treat them as one audience, you waste effort. If you understand what each one favours, you can aim your work where it actually counts.

This is a companion to our complete guide to Answer Engine Optimisation for local businesses: start there for the full picture, come here for how the engines differ.

Why "where the AI reads" matters more than "what your website says"

Most owners assume AI visibility is a website job: write the right words on your own pages and the AI will find you. Your website matters, but it is only one input. The engine is reading the whole web about you, and it weights some places far above others.

This shift is already mainstream, not a future worry. AI-generated summaries now sit on top of a large share of everyday searches, and when one appears people click through to a normal result far less often. Ahrefs measured a 34.5% lower click-through rate for the top-ranking page when an AI Overview is present, across a sample of 300,000 keywords (Ahrefs, AI Overviews Reduce Clicks by 34.5%)^[1]. People are reading the answer and stopping. So the question is no longer "where do I rank?" It is "which sources does the answer get built from, and am I in them?" The sources differ by engine, so let us take them one at a time.

ChatGPT: it trusts authority and the encyclopaedia

ChatGPT behaves like a careful researcher who reaches for a reference book first. Its single most-cited source by a wide margin is Wikipedia.

A Semrush study that tracked more than 100 million AI citations in weekly snapshots between July and October 2025 found that, even after a sharp drop in how often ChatGPT leaned on them, "Reddit and Wikipedia are still ChatGPT's two most-cited domains" (Semrush, The Most-Cited Domains in AI, 2025)^[2]. An independent analysis of 30 million cited sources by Peec AI, reported by Search Engine Land, points the same way: ChatGPT "favored Wikipedia, Reddit, and editorial sites like Forbes"^[3].

After Wikipedia, ChatGPT's top sources are a mix of established media and review-style sites. The thread running through them is perceived authority and editorial standing, not raw popularity. That preference shows up in the numbers: a SE Ranking study of 129,000 domains and more than 216,000 pages found that sites with a Domain Trust score above 90 earned close to four times as many ChatGPT citations as sites below 43 (roughly 8.4 citations per page at the very top versus about 1.6 at the bottom)^[5].

The Semrush data also shows how quickly this can move: ChatGPT reweighted its top sources in mid-September 2025, which is a reminder that these are habits, not fixed rules.

What this means for a local business

You will not out-Wikipedia Wikipedia, and as a single-location business you almost certainly will not get a Wikipedia page at all. That is fine, and chasing one is a waste of time. The play is different:

• Be accurate and consistent on the authoritative sources that already exist for your sector. For a local estate agent that might be a recognised property portal and an industry body listing. For a driving instructor it might be the official register of approved instructors. ChatGPT trusts these the way it trusts Wikipedia, and you can actually appear on them.
• Earn a mention in established local or trade press. A roofer quoted in a regional paper's "how to spot storm damage" piece, or a caterer featured in a county lifestyle magazine, is exactly the kind of editorial, authoritative source ChatGPT favours.
• Get the facts straight everywhere. ChatGPT is reaching for confirmable facts. If your name, address, services and credentials read the same across every authoritative listing, you are an easy, safe source to cite. Contradictory details make you a risky one.

Google AI Overviews: it trusts the crowd and the video

Google's AI Overviews behave almost in reverse. Where ChatGPT reaches for the reference book, Google reaches for the conversation and the demonstration.

The same 30-million-source analysis found Reddit to be the most-cited domain across the major engines, with YouTube and LinkedIn also in the top five, and noted that Google in particular "leaned toward platforms like Facebook and Yelp"^[3]. The Semrush data adds that Google's AI Mode has "a clear preference for Google's owned domains" such as YouTube and Google's own properties^[2]. Wikipedia, which is a top source for ChatGPT, barely features in Google's picture. Google is pulling from a balanced mix of community discussion, video and professional networks rather than deferring to one encyclopaedic source.

That makes intuitive sense. Google owns YouTube and has a longstanding deal to surface Reddit content, and its whole search history is built on weighing many signals rather than deferring to one. The takeaway for you is that real, human, demonstrable content travels well in Google's AI answers.

What this means for a local business

• A simple video presence punches above its weight. A locksmith filming a sixty-second "how to tell if your lock needs replacing", or a physio demonstrating a stretch, gives Google exactly the kind of source it likes to cite. It does not need production polish, it needs to be genuine and clearly labelled with who you are and where you operate.
• Genuine participation in relevant discussion threads helps. If people in a local community forum or a trade subreddit are asking "who's good for X near [town]?", being a genuinely helpful voice there (never an astroturfing one) puts you in the source pool Google draws on. Our guide to showing up on Reddit the right way covers the white-hat way to do this.
• Keep your Google Business Profile complete and current. For local questions specifically, Google leans heavily on its own profile data. An incomplete or unclaimed profile is the most common reason a business is missing from Google's local AI answers.

Perplexity: it is built on Reddit

Perplexity is the most extreme of the three. It is, to a striking degree, a Reddit reader with a polished interface.

The independent 30-million-source analysis singled Perplexity out as emphasising "Reddit, LinkedIn, and G2 for B2B queries", with review platforms such as Yelp and G2 appearing often in recommendation queries^[3]. Semrush's tracking similarly puts Reddit among Perplexity's top sources throughout its study^[2]. The picture is clear: Perplexity wants community discussion and peer recommendation above almost everything else.

There is a useful flip side. Of the three engines, Perplexity behaves the most like classic search, matching the words in your content closely. That means the traditional SEO work you may already have done is not wasted on Perplexity; clear, keyword-clear pages still help you there. We cover that in our Perplexity playbook.

What this means for a local business

• Genuine reviews and recommendation-site presence matter most here. A car garage with steady, recent reviews on the review platforms that matter in its trade is feeding Perplexity exactly what it prizes.
• Authentic community discussion is the highest-impact off-site work for Perplexity. Be the helpful local expert who answers real questions in the places your customers actually gather. Do it as yourself, openly, and never plant fake recommendations: AI engines and communities both punish that, and it is increasingly illegal.
• Keep your plain-language service pages tidy. Because Perplexity matches wording closely, pages that describe your services the way customers phrase them ("emergency boiler repair in [town]") give Perplexity something direct to match.

The pattern underneath all three

Step back and a single lesson emerges. Every engine, despite its different favourites, is doing the same thing: trusting a small set of sources it considers reliable for the question, then building an answer from them. None of them is mainly reading your homepage. (This is also why a household name does not automatically win the answer when a smaller, better-sourced business is the more relevant match.)

That is why AEO is not a website-only job. What actually counts is spread across the places the engines actually read:

• Authoritative and editorial sources (sector bodies, recognised directories, local and trade press) feed ChatGPT.
• Community and video (Reddit, YouTube, Quora, your Google Business Profile) feed Google's AI Overviews.
• Reviews and community recommendation (Reddit, Yelp, TripAdvisor and the review sites in your trade) feed Perplexity.

A local business that is accurate on the authoritative sources, genuinely present in the relevant communities, steadily reviewed, and clear on its own pages is feeding all three engines at once. You do not need a separate strategy per platform so much as a presence broad enough that whichever source an engine reaches for, you are in it.

A simple cross-engine plan

You do not have to do everything. Ordered roughly by impact for a typical local business:

1. Claim and complete your Google Business Profile. This single asset feeds local answers across Google directly and informs the others indirectly. It is step zero.
2. Get accurate on the authoritative sources for your sector. List on the recognised industry body and the directories that matter in your trade, with details that match your website exactly. This is your ChatGPT play.
3. Build steady, recent reviews on the platforms that count in your trade. This is your Perplexity play and a strong signal everywhere.
4. Add a little genuine video and genuine community participation. A few plain-spoken videos and helpful forum answers cover the Google and Perplexity community appetite.
5. Make your own pages answer real questions in plain words. Service pages and area pages phrased the way customers ask, which helps Perplexity match you and gives every engine something clean to quote.
6. Keep your core facts identical across the whole web. Name, address, phone and services the same everywhere, so no engine has a reason to doubt who you are.

Common mistakes

• Treating all three engines as one audience. Pouring everything into your website and expecting Perplexity, which lives on Reddit and reviews, to notice.
• Chasing a Wikipedia page you will never get. Better to be accurate on the sector authorities you can actually appear on.
• Faking community presence. Planting reviews or pretending to be a happy customer on a forum is transparent, counterproductive and increasingly unlawful. Every engine is reading the same threads your customers are.
• Ignoring video because it feels like hard work. A sixty-second phone video is enough to give Google and Perplexity something to cite.
• Letting your details drift. An old phone number on one directory and a new one on another quietly lowers how confident every engine is about you.
• Assuming a Google ranking covers it. Being first on Google and being named in an AI answer are now two different jobs, as our guide on why a No.1 Google ranking means nothing in ChatGPT explains.

Frequently asked questions

Why does ChatGPT cite Wikipedia so much but Google barely does?

They have different design philosophies. ChatGPT reaches for authoritative, encyclopaedic content as a baseline, so Wikipedia remains one of its two most-cited domains (Semrush, 2025)^[2]. Google's AI Overviews lean on community discussion, video and professional networks, where Reddit, YouTube and platforms like Facebook and Yelp lead, and Wikipedia barely features (Search Engine Land, reporting Peec AI)^[3].

Do I need a different strategy for each engine?

Not really. The smarter approach is a presence broad enough that whichever source an engine prefers, you are in it: accurate on authoritative sources for ChatGPT, present in communities and video for Google, steadily reviewed for Perplexity. One broad foundation feeds all three.

Does the AI keep my town when it searches?

Generally yes. OpenAI's own help documentation explains that ChatGPT search rewrites your question into targeted queries and uses your general location to improve results, giving the example of turning "good restaurants near me" into a city-specific search (OpenAI Help Center, ChatGPT Search)^[4]. Location is the signal these tools hold onto, which works in a local business's favour.

Is Reddit really that important?

For Google AI Overviews and especially Perplexity, yes. An independent analysis of 30 million cited sources found Reddit to be the single most-cited domain across the major AI engines, with Perplexity leaning on Reddit particularly hard (Search Engine Land, reporting Peec AI)^[3]. The key is to take part genuinely and openly, never to fake it.

My business is tiny. Can I really show up next to bigger names?

For local questions, yes. The engines weight location and reviews heavily, and you only have to be the clearest, best-documented answer in your own town, not the whole country. That is a far smaller hill to climb than competing nationally.

What actually makes ChatGPT more likely to cite a source?

Perceived authority, not popularity. A SE Ranking study of 129,000 domains found that sites with a high Domain Trust score were cited far more often, close to four times as much above a score of 90 as below 43. That is why the play for a local business is to be accurate and consistent on the authoritative sources that already carry weight in your sector, rather than relying on your own site alone.

Which single asset helps most across all three engines?

For local questions, a complete and current Google Business Profile. It feeds Google's local answers directly and gives every engine a consistent set of core facts (name, address, phone, services) to confirm you against. It is the step-zero asset before anything else.

Does video really matter, or is that just for Google?

It leans towards Google, where YouTube is a favoured source, but a plain-spoken sixty-second video also gives Perplexity something genuine to cite. It does not need production polish: it needs to be real, clearly labelled with who you are and where you operate, and answer a question a customer actually asks.

If my details differ slightly across the web, does it really matter?

Yes. Every engine is assembling a confident picture of who you are, and an old phone number on one directory against a new one on another quietly lowers that confidence. A less sure engine cites you less often, so keeping your name, address, phone and services identical everywhere is low-effort, high-value work.

Is my own website pointless for AI visibility, then?

No, it is just one input rather than the whole job. Clear service and area pages phrased the way customers ask give every engine something clean to quote, and they help Perplexity match you directly because it reads your words closely. The point is that your website works alongside the off-site sources each engine trusts, not instead of them.

Where to start

If you do only one thing this week, complete your Google Business Profile. After that, pick the engine your customers use most and feed its favourite source: authoritative listings for ChatGPT, reviews for Perplexity, a little video and genuine community presence for Google.

If you would rather see exactly which engines name you, which name your competitors, and which sources they are drawing on, that is what a QBiz AI Visibility audit does. We map which source each engine leans on for your category, show where you are absent from those sources, and rank the gaps worth closing.
