TL;DR: When ChatGPT answers a question using the web, it shows which pages it took the information from. Those links used to sit behind a button marked “Sources” at the bottom of the answer, in plain view. This week that button quietly moved into the three-dot “More actions” menu — the little overflow menu almost nobody opens. Which pages ChatGPT uses has not changed. How many readers ever find out has. If you report on AI search by counting the visitors who arrive at your site from ChatGPT, expect that number to drop for a reason that has nothing to do with your website.
First, what is a “source” in an AI answer?
Ask ChatGPT a question and it writes you a paragraph. To write that paragraph it often goes and reads real web pages first. A source is one of those pages, and a citation is the link back to it.
That link is worth something in two separate ways, and they are easy to confuse.
The first is credit. Your page was chosen out of everything on the web, and your brand got attached to the answer. The second is traffic — an actual human clicks the link and lands on your site, where your analytics can see them. Referral traffic is just the industry’s word for visitors who arrived by clicking a link somewhere else.
You can have the first without the second, and the gap between them is what this week’s change widens.
What actually changed
Until now, a ChatGPT answer that used the web carried a visible “Sources” button in its footer. One click and you got the list of pages.
The independent analyst Glenn Gabe noticed that the button is gone from the footer for at least some users. The sources are still there, but you now have to open the three-dot “More actions” menu first, then choose to view them. Search Engine Roundtable’s Barry Schwartz wrote it up on 13 August, and Optimixed covered the same change the same day.
Two clicks instead of one sounds trivial. In interface terms it is not. Anything moved into an overflow menu — the three dots that hide the options a product considers secondary — falls off a cliff in usage, because people click what they can see and ignore what they cannot.
OpenAI has not explained the change and has not said whether it is a test or permanent. Gabe’s own reading is that source links may be losing shelf space to something OpenAI would rather you looked at, ads among them. That part is speculation, clearly labelled as such by everyone reporting it, and worth treating that way.
This is a direction, not an incident
Three weeks ago we wrote about Google AI Mode and ChatGPT both testing citations at the bottom of the answer rather than woven into the text, as first reported on 22 July. Now ChatGPT has taken the next step and moved them off the answer entirely.
Read those two moves together and the pattern is hard to miss. The answer is the product. The sources are the paperwork behind the product, and the paperwork keeps getting filed further away.
None of this is a ranking change. Nobody demoted you. The engine is just deciding, repeatedly, that the link matters less to its readers than the text does.
What it does to your reporting
Here is the practical consequence for anyone who reports AI performance to a client.
If your AI-visibility number is really a referral-traffic number, it is about to fall. Not because the client’s content got worse, and not because a competitor overtook them, but because a button moved. If you cannot separate those causes, you will spend a September call apologising for a chart you cannot explain, and possibly rewriting content that was working fine.
So separate them now, before the drop lands:
- Report citations and clicks as two different lines. “We were cited in 41 answers” and “we received 12 visits from those answers” are different facts, and only one of them is under your control.
- Warn the client before the number moves. A drop you predicted is a demonstration of competence. The same drop explained afterwards sounds like an excuse.
- Stop treating referral traffic as the health check for AI search. It was always a weak proxy. It is now measuring the interface as much as the content.
- Write so the brand survives a hidden link. If your name only exists in the URL, it disappears the moment the URL does. If the model can say “according to Redwood Legal” because the page states plainly who is making the claim, you keep something even when nobody opens the menu.
- Keep the page extractable. One clear H1, the answer near the top, claims stated in full sentences rather than implied across three paragraphs. Standard hygiene, now with a sharper reason.
That fourth point is doing more work than it looks. A named mention inside the answer text is the one form of AI visibility that no interface change can bury.
Measuring any of this by hand is the awkward part. Checking whether a client is cited means running the same questions across several engines, repeatedly, and noticing what moved. Preferium tracks citations across four AI engines — ChatGPT, Claude, Perplexity and Gemini — on every plan, with Google AI Overviews and AI Mode tracked separately, so citations get counted as citations whether or not anyone clicks through. That is six answer surfaces measured independently of your referral logs. More on how the system works, and we went through the measurement problem in more detail in measuring AI citations.
Key takeaways
- ChatGPT’s “Sources” button has moved from the answer footer into the three-dot “More actions” menu, spotted by Glenn Gabe and reported by Search Engine Roundtable and Optimixed on 13 August.
- OpenAI has given no explanation, and has not said whether this is a test or a permanent change.
- Nothing about which pages get cited has changed — only how visible those citations are to the reader.
- It follows the 22 July reports of both ChatGPT and Google AI Mode pushing citations to the bottom of the answer. The trend is consistent.
- Expect ChatGPT referral traffic to fall for interface reasons. Tell clients before it happens, not after.
- Track citations separately from clicks, and make sure your brand is named in the page’s own words so a hidden link is not the only thing carrying it.
