The short version:
site: queries at scale, going to specific authoritative domains instead of searching the open web and seeing what came back.Promptwatch, which samples the actual interfaces of the major AI platforms, had Reddit holding a stable 3.83% share of ChatGPT Search citations from July 18 through August 7. On August 8 it slipped to the mid-2s. On August 14 it fell off a cliff — under 1%, averaging 0.52% through August 17. That's an 86% relative decline, and Reddit had been one of the single most-cited domains in ChatGPT. It peaked at 4.14% back in April.
Google's surfaces moved in the same direction but nothing like as fast: AI Overviews down 11.3% over the period, AI Mode down 30.5%.
Worth noting that a second tracker, Qwairy, measured the same event and got 2.05% falling to 0.07% — a 95% collapse from a much lower baseline. Two credible sources, same week, materially different numbers. Promptwatch itself says the drop size is provisional and it can't rule out a collection error on its own end.
I'm not raising that to be pedantic. I'm raising it because a lot of people spent last week making strategy decisions off a number that the people who produced it are still hedging on.
On August 8, ChatGPT changed how it searches.
Its background "fanout" queries — the searches it fires off behind the scenes to assemble an answer — started using the site: operator at a scale that had never been observed before. Promptwatch clocked the jump from 0.37% of fanout queries to 16.8% overnight, a 46-fold increase, climbing toward 23–24% by mid-August. Average fanout queries per response nearly doubled.
Promptwatch co-founder Klaas Foppen put it well: ChatGPT "is no longer just searching the open web and seeing what comes back; it is deliberately going to specific sites."
And those site-restricted queries almost never point at Reddit. They point at brand domains, government portals, regulators, institutional sources. Qwairy's cohort data shows the shape of it clearly: institutional and government citations up 73%, press and media down 82%, forums and user-generated content down 70%.
So this was not necessarily a judgment about Reddit's quality. Reddit simply lost the structural advantage it had, which was being everywhere in the open-web index for long-tail conversational queries.
Should I still invest in Reddit? Two important questions you need to ask yourself.
1. Are your buyers actually there, and can you say something useful? Then yes. Same as it's always been. Reddit still shows up in 11.3% of LLM responses across ChatGPT Search, Perplexity and Google AI Mode. It's still one of the highest-trust corners of the web precisely because people there can smell a pitch from a hundred miles away. Show up as yourself, answer things properly, take the occasional beating.
2. Are you paying GEO agency to seed questions and answer them in your brand's voice? If you're trying to bulldoze your brand into a community that can smell bullshit 100 miles away, maybe think again.
Ross Simmonds, one of the leading voices on Reddit Marketing, puts thing nicely in perspective:'
Strip out the specifics and this is a story SEO has told roughly every eighteen months since 2010. Exact-match domains. Article directories. Guest post networks. Expired domains. Parasite SEO. Programmatic SEO. Scaled AI content. Every one of them "worked", produced fancy case studies, spawned agencies, and then abruptly fell off a cliff.
The people who came out of last week unbothered were the ones for whom Reddit was a place they participate, not a channel they exploit.
Stop chasing the shiny new thing and trying to hack your way to success. It's going to leave you exhausted and depleted.
Put in the reps. Develop a great product that people love. Create content that no one else can replicate. Cultivate an audience. Contribute meaningfully. Build trust.
Hacks will get you results tomorrow, but what about next month, next quarter, or next year?
Yeah, it's a long game.
