AI tools like ChatGPT, Perplexity, and Google AI Overviews rarely open their answers with your website. They open with Reddit.
Ask ChatGPT for a best digital marketing agency in Toronto, or good electrician in North York, or ask Perplexity to compare bookkeepers in Etobicoke, and the answer isn't pulled from either business's homepage. It's assembled from Reddit threads, Quora answers, and a short list of publications the model has learned to trust. Reddit alone shows up in more than 40% of AI-generated answers, ahead of Wikipedia, YouTube, and Google's own search results. For a Toronto business that has never posted on Reddit or Quora, that's an entire discovery channel running with zero visibility, and no idea it's even missing.
That's the shift in one sentence: search used to be ten blue links you competed for. Now it's a paragraph an AI writes on the customer's behalf, built from sources that are almost never your homepage.
What counts as an AI citation#
An AI citation happens whenever ChatGPT, Perplexity, Claude, Gemini, or Google AI Overviews pulls from a specific source to build an answer. Some tools show it as a clickable link. Others weigh the source without ever displaying it. Either way, it shapes what the model says.
The distinction that matters: a business named inside a Reddit thread reads to the model as a signal from an actual customer. The same business named on its own website reads as advertising. AI models are trained to weight the first kind of mention more heavily than the second, which is really the whole story in a sentence. (If terms like this one, sometimes shortened to AEO or GEO, are new to you, our marketing glossary breaks down the rest of the AI-search vocabulary.)
Why Reddit and Quora keep winning the citation game#
Three structural reasons, and none of them are going away soon.
Format. Reddit and Quora are built as question-and-answer threads, which happens to be exactly the shape a language model needs when it's answering a natural-language question. "We are Toronto's leading HVAC company" doesn't resemble a query. "Any recommendations for HVAC repair in East York, my furnace died last night" resembles one almost exactly.
Freshness and specificity. When someone asks an AI about a Toronto electrician, roofer, or bookkeeper, the model is after recent, geographically specific, opinionated content written by people who sound like actual customers. That's what Reddit produces constantly. A polished service page, no matter how well written, doesn't read that way.
Community validation. Upvotes, comment counts, and awarded flair are signals a model can read the same way a human scans for social proof. A local subreddit post with forty upvotes and a long thread underneath carries more weight than a static page ever will.
Quora plays a smaller role than Reddit but a real one, especially in professional-service categories like legal, tax, medical, and B2B. It shows up less often in AI Overviews and Perplexity than Reddit does, but it's frequently the deciding citation on how-to and definitional questions.
The numbers, and where they come from#
A lot of stats get repeated in this space without anyone checking the source. Here's what's verifiable, and who published it.
- Semrush's June 2025 analysis of 150,000 AI citations across 5,000 keywords found Reddit referenced in 40.1% of answers, ahead of Wikipedia (26.3%), YouTube (23.5%), and Google's own organic results (23.3%). (Semrush)
- A separate Semrush study looked at 248,000 individual Reddit URLs cited across ChatGPT Search, Perplexity, and Google AI Mode. More than half came from Q&A-style threads, with comparison and discussion posts close behind. (Semrush)
- Citation-tracking firm Profound, which analyzed roughly 700,000 social-platform citations inside ChatGPT, found that 99% of Reddit links point to individual discussion threads, not subreddit homepages, brand pages, or user profiles. Models are citing conversations, not the platform itself.
- Industry tracking through early 2026, reported by Search Engine Land, found Reddit's citation share growing by at least 73% across every tracked commercial category between October 2025 and January 2026, and Reddit accounted for 44% of the social citations specifically inside Google AI Overviews. (Search Engine Land)
- Part of Reddit's rise traces back to money changing hands: in February 2024, Google agreed to pay Reddit roughly $60 million a year for structured, real-time access to its data. (CBS News)
Broken down by platform, the split between the two communities looks like this:
AI platform Reddit's citation share Quora's role Perplexity Roughly 47% of top-cited sources, the highest of any engine we could find data on Present but secondary, strongest on definitional questions Google AI Overviews 44% of social-platform citations Shows up alongside Reddit, more often on professional-service queries ChatGPT A smaller overall share, but 99% of the Reddit links it does cite point to individual threads Occasional citations, mostly on how-to questions Gemini Drops to around 5% of social citations, the lowest of the four Limited public data; low community-citation volume generally
(Reddit figures per Profound and the Search Engine Land coverage linked above. We couldn't find a Quora-specific breakdown by platform from a source we'd trust, so that column stays qualitative rather than guessing at a number.)
None of this behaviour existed two years ago. It's changing every quarter, which is worth remembering before you build a strategy around any single number in this list.
Where this leaves a Toronto service business#
Ranking first on Google for "plumber Etobicoke" no longer guarantees an AI recommends you. The model is reading r/toronto, r/askTO, r/PersonalFinanceCanada, and whatever category-specific thread it can find, then building its answer from that, not from your rankings.
A question owners ask immediately: can I just run Reddit ads instead? No. Reddit ads don't feed AI citations. Organic threads do, and there isn't currently a shortcut around that.
This is one piece of a bigger split we've written about before. If you're ranking well on Google but invisible on ChatGPT or Gemini, we cover why that gap existsand what closes it here. And if a growing share of your traffic seems to be disappearing before anyone even clicks, that's the zero-click searchpattern, a related but separate problem.
The practical takeaway: a Toronto business now needs a real, thin, ongoing presence in the two or three subreddits and Quora topics where its actual customers ask questions. Not a campaign you run for a month. A presence you maintain.
Building a Reddit and Quora presence that works#
Not spam. Not link drops. Reddit will flag a promotional account inside a week, and AI models are learning to discount content that reads like a press release. What works looks closer to how a trusted regular behaves in a local Facebook group than anything resembling a marketing campaign.
Pick the right two or three communities. A Toronto HVAC contractor might use r/toronto, r/HomeImprovement, and a neighbourhood sub like r/vaughan or r/askTO. A bookkeeper might use r/PersonalFinanceCanada, r/CanadianInvestor, and r/smallbusiness. Choose based on where your customers already spend time, not where competitors happen to post.
Post from a real account with real history. Comment on other threads first. Answer questions in your area of expertise where no strong answer exists yet, in the voice of a knowledgeable neighbour, not a marketer. If you name your business, do it the way a customer would, briefly and only when asked, and honour any subreddit rule against self-promotion.
Go after buyer-intent questions specifically. Threads like "how much should X cost in Toronto," "any recommendations for Y in the west end," or "is Z worth it for a small business" are exactly the queries AI models pull from when building recommendation answers. The same logic carries over to Quora: answer with concrete detail and real Toronto context, and skip the corporate voice that flags an answer as low-signal.
What not to do#
Don't open five accounts and start dropping links. It's the fastest way to get every mention of your business scrubbed from the platforms AI models trust most.
Don't paste marketing copy into an answer. The entire reason AI cites Reddit is that Reddit doesn't read like marketing copy, so matching that voice isn't optional.
Don't chase ten subreddits at once. Depth in one community beats a shallow footprint spread across many.
And don't treat any of this as a replacement for SEO or paid search. Google Ads captures active intent, SEO captures search behaviour, and Reddit and Quora presence shapes what the AI says about your business when the customer isn't searching at all, just asking a question in plain English.
One risk worth naming: this keeps shifting#
AI citation behaviour is not stable, and treating any single snapshot as permanent is a mistake. Semrush's own tracking showed ChatGPT citing Reddit in close to 60% of prompt responses in early August 2025, then collapsing to around 10% by mid-September before partially recovering. Semrush's Head of Organic and AI Visibility attributed the swing to OpenAI adjusting how heavily it weights any single source. (Semrush)
That volatility is a reason to diversify, not to sit this out. Spread effort across three to five subreddits and one Quora topic, and check periodically how you appear across ChatGPT, Perplexity, Google AI Overviews, and Gemini rather than assuming today's snapshot holds. Concentrating everything on one subreddit or one AI engine is fragile by design.
[If you're already running a Reddit or Quora presence for a client and have a real before-and-after result, that's worth adding here. A genuine example will do more for this section than another statistic.]
What to do this week#
Pick one decision and one action, nothing more.
Choose the single subreddit where your customers are most likely to ask questions about your category in Toronto. Read the last month of posts there. Find three questions where a knowledgeable, honest answer would genuinely help someone, and write those three answers. Don't link to anything. Don't name your business unless someone asks. Watch what happens over the next thirty days.
That's the starting position. Everything else compounds from there.

FAQ#
Does posting on Reddit actually change what AI models say about my business? Indirectly, yes. AI models pull from threads that mention your category, your neighbourhood, and specific businesses by name. Contribute consistently and get real engagement, and your name enters the pool of content the AI cites from. Expect a 60- to 90-day lag before it compounds, not a same-week result.
Should I post under my own name or create a business account? Use a real personal account with genuine posting history and occasional, honest disclosure that you work in the field. Reddit moderators are unusually good at spotting brand accounts, and AI models are learning the same tells. Anything that reads as corporate gets discounted by both.
Does this replace Google reviews and local SEO? No, and it's not meant to. AI models cite Reddit heavily for recommendations and comparisons, but they still lean on Google Maps, review sites, and directories for local trust signals. You need both channels covered; Reddit and Quora fill a gap most Toronto businesses have simply never touched.
How often do I need to post? Two or three thoughtful contributions a week in one or two subreddits will do more for AI citation value than daily posting across ten. The signal models weight is quality and community response, not volume. One answer with fifty upvotes outperforms twenty answers with none.
Can I outsource this to an agency? Parts of it. Research, thread identification, and voice-matched drafts can be handled externally. What can't be outsourced is the underlying expertise and the willingness to sound like a person instead of a brand. An answer that reads as ghostwritten gets discounted by the community and, increasingly, by the AI models reading it too.
