On 14 August 2026, Reddit fell out of ChatGPT's citations. Not gradually. In one step, from an average 3.83% of ChatGPT Search citations to 0.52%, and it has not come back. In April, Reddit was the single most cited domain of all, at 4.14%.
We sell a Reddit tool, so this is the kind of news you would expect us to bury. We would rather write it down, because half of what you read about AI search this month will be people selling you a fix for it.
The numbers
The measurements come from Promptwatch, which tracks citations across the real interfaces of the main AI platforms rather than through an API.
What caused it
Nothing about Reddit. On 8 August, ChatGPT started running site-scoped searches at scale, jumping from 0.37% to 16.8% of its fan-out queries. Instead of searching the open web and using whatever comes back, it decides which sites to open and goes there. Reddit was the biggest winner of the old behaviour, so it was the biggest loser of the new one.
That is a retrieval config, not a verdict on Reddit's content. Which is exactly why nobody should have built a growth strategy on it, us included.
A channel you do not control can halve overnight, and nobody sends you an email about it.
What we changed here, the same week
Our own site was making that promise in four places. All four are gone or rewritten:
What it means if you market on Reddit
Less than the headlines suggest. The person writing "what do you use for X" in a thread is a buyer today, and no model has to quote them for you to get that customer. The comment still sits in the thread, still ranks on Google, still gets read by the next person with the same problem, for months.
Citations were the bonus on top. If you were doing Reddit only to feed ChatGPT, that math changed. If you were doing it to be in the room when someone asks, nothing changed.
If you do want ChatGPT to cite you
It now goes site by site, so the site it opens has to hold the answer. Put the answer in the first paragraph, add FAQPage and Article schema with real dates, publish your docs and help pages properly, and stop inventing ratings. Those are the pages a site-scoped search lands on.
Will it come back?
Maybe. It was a mechanical change and OpenAI can tune it back next month. We are not going to guess. On the Scale plan Karmy checks each week whether ChatGPT names your product, so you can watch the line instead of reading threads about it.
