Open your analytics and filter referrals by chatgpt.com. If the line bent upward somewhere around the second week of May, you are looking at one of the quietest big changes in search this year. On May 7, ChatGPT changed how it presents brands: instead of burying sources in footnotes, it started placing brand names as clickable links directly inside the answer text.
The effect was immediate. Similarweb's tracking put the jump at 157.7% more ChatGPT referrals week over week, with traffic landing directly on brand homepages up 354.7%. That is not a gradual trend line. That is a switch being flipped.
Why this changes the AEO argument
Until May, the honest pitch for AI visibility work was defensive: buyers are asking models instead of Google, mentions decide the sale, and you cannot see any of it in analytics. All still true. But the update adds something the sceptics kept asking for — a line in the dashboard. A mention in a ChatGPT answer is no longer just influence you have to take on faith. It is a link a buyer can click, and increasingly does.
The quality of that click is the part I would put in front of a client. Across the studies published this year, ChatGPT referrals convert at around 7.1% — just behind paid search at 7.8%, and comfortably ahead of organic, direct, social and email. Goodie's cross-brand panel measured engagement too: visitors arriving from AI assistants spend about 58 seconds engaged, roughly 30% longer than Google organic. Someone who just asked a model for a recommendation and clicked the answer is about as warm as a visitor gets.
The model does the qualifying. By the time the click happens, the buyer has already been told you are the answer.
Who gets the link
Here is the uncomfortable part: the update did not create new winners. It paid out to the brands that were already being named. ChatGPT links the brands it mentions — so everything that decided mentions before May decides clicks now. Clear, quotable pages. Fresh third-party reviews and roundups. Presence in the communities the model reads. If you were absent from answers in April, you got 0% of a 157% increase.
What to actually do with this
- Segment AI referrals in your analytics now — chatgpt.com, perplexity.ai, copilot.microsoft.com as a named channel. You want the baseline before you start improving it, and Search Console's AI report will not supply it.
- Check where those clicks land. The update sends a striking share of traffic to homepages. If your homepage assumes the visitor already knows you, rewrite the first screen for someone who arrived from one sentence of context.
- Run your buying prompts and see who ChatGPT links today. Every brand it links instead of you is a measurable, clickable gap.
- Re-check monthly. The engines change presentation without notice — May proved how much can move in a week.
Keep the volume honest
None of this means AI referrals will outnumber Google's tomorrow. For most sites they are still a small line — publishers with heavy citation counts still report under 1% of referral traffic from AI platforms. The case is not volume. It is that the smallest channel in the report converts almost like paid search, costs nothing per click, and compounds with the same AEO work you should be doing anyway. Small, warm, and growing beats big and indifferent more often than dashboards admit.
How to improve my brand's visibility in ChatGPT and Perplexity?
Both engines link the brands they already name, so the work sits upstream of the link. Write pages that put the conclusion in the first sentence, because a model quotes what it can lift cleanly. Get onto the roundups and review pages the engines actually cite in your category — you find those by reading the citations under the answer, not by guessing. Keep those third-party mentions current, since a review from 2023 carries less than one from this year.
The two engines do not weight the same things. Perplexity leans on community sources far harder than ChatGPT does — Reddit is its single largest source — so a real answer in a thread your buyers read is worth more there than another page on your own domain. AnswerPeek closes the loop on both: it runs your prompts on a schedule, shows which sources each engine cited, and flags the cited pages that name a competitor and not you.
