ChatGPT Search changed how it looks things up on 8 August.
It started using site: at scale. Promptwatch saw those domain-scoped searches jump from about 0.4% of background queries to about 17% in a day. Same week, the queries started saying “official” more often.
@suganthan has been reading the traffic: one search that already names the brands, then a site: look-up on each brand’s own website for pricing and specs.
Reddit’s share of citations inside ChatGPT Search then fell from 3.83% to 0.52% between 14 and 17 August. The first slip was 8 August, the same day as the site: change. Google’s AI Overviews and AI Mode did not do this.
So this is not “Reddit stopped working.” People still read it. Google still cites it. We still do that work with clients. Most discovery is not ChatGPT Search. What changed is ChatGPT Search asking official sites first, and Reddit is not an official site.
OpenAI has not said why. Two reads both fit.
One is quality. For a year it was pulling the same gamed listicles everyone in SEO already hates. Judging a random page at ChatGPT’s volume is expensive. Searching site: or a .gov is a shortcut.
@lilyraynyc write-up this week is that idea: site: as a blunt trust filter.
The other is cost and speed. A short list of official domains is cheaper and faster than wandering the open web. From the outside those two look the same.
There is a catch. If it guesses the wrong official domain, it searches a parked site. That has already been shown. This is not a clever authority system. It is a blunt one.
What to do this week is still the same test Suganthan published. Ask the category question your buyers ask, five times. Read the search queries ChatGPT wrote. The names that appear every time are the shortlist in its head.
If you are never on it, a perfectly structured page will not get you named in ChatGPT Search this week. The work is getting written about: reviews, roundups, comparison pages, the publications your category already reads, communities, people arguing about you in public. Same family of work as Reddit. Not a replacement for it, and not a reason to stop.
If you are on it every time, then the page work is what’s left. Make sure your own site survives the site: look-up: pricing, specs, the actual answer, in plain HTML.
