'Quality Over Quantity': Reddit Is Mostly Wiped From ChatGPT Citations

Nature is healing, with the latest data from the AI search visibility platform Promptwatch showing that OpenAI's ChatGPT citations from Reddit have plunged in recent weeks to nearly zero.

"It looks like Reddit is almost wiped from ChatGPT sources; the query fanout changes had a big impact, and in the past couple of days it seems to be almost completely removed from prompt responses," Promptwatch founder Klaas Foppen wrote on X.

According to Promptwatch, Reddit's daily share of all citations returned by ChatGPT Search began to move sharply lower in the first week of August, then fell to near zero by mid-month.

Promptwatch's website said the red lines on the chart began on August 8, when OpenAI changed the query fanout behavior of ChatGPT Search. By August 14, or last Friday, those citations had plunged again to near zero.

Promptwatch continued:

Reddit lost almost its entire citation footprint in ChatGPT within a single day. From July 18 through August 7, it held a steady 3.83% average share of ChatGPT citations, one of the largest of any domain. On August 14, the share collapsed to under 1%, and the August 14-17 average of 0.52% is an 86.4% relative drop.

The slide started earlier: on August 8, the same day ChatGPT changed its query fanout behavior, Reddit's share fell from the high 3s to the mid-2s. The chart shows when each change happened, not why. A shift in ChatGPT's source selection is the obvious candidate, but a data-collection issue cannot be ruled out, so treat the size of the drop as provisional while we keep monitoring.

Reddit citations in ChatGPT have been controversial from the start because there is often no confirmation of where the information originated, and the citations could point to someone claiming to be an engineer, doctor, trader, or insider without proving their credentials. There's also the fact that Reddit generally leans left-wing, which could alter answers.

All-In Podcast's Jason Calacanis asked Grok, "Is this a choice because of quality or because of legal IP issues?"

The answer:

Mostly quality. OpenAI shifted ChatGPT Search query fanout around Aug 8 to heavy use of site: operators targeting trusted domains. This cut Reddit citations from ~3.8% to 0.5% by Aug 14 (Promptwatch data) to reduce spam and low-quality results. The 2024 licensing deal for…

Foppen noted that instead of ChatGPT tapping Reddit, more official sources and direct-site citations are being pulled.
