If your Direct traffic keeps going up and nobody can explain why, I’d look at AI first.
Searchable data shows Direct went from about 27% of visits on the median site in May to 33% in October. Organic slid from about 26% to 23% over the same stretch (with AI Mode and AI Overviews counted in Organic). And the sites getting the most AI traffic saw Direct grow about 3x as much as sites getting almost none.
I honestly think a lot of this is AI. Someone asks ChatGPT, closes the app and types your name in later, or the app just doesn’t pass along where they came from. GA4 can’t tell the difference, so it all lands in Direct.
This is what I’d check on my own site (maybe 20 minutes total).
1. Make an AI channel in GA4. Go to Admin, then Channel groups, and add a channel where the source matches chatgpt|perplexity|claude|gemini|copilot. Move it above Referral. It works on your old data too, so you’ll see the AI clicks you’ve already been getting.
2. Filter your landing pages to Direct only. Nobody types a long blog URL from memory, so Direct visits to deep pages are usually links copied out of somewhere, like an AI chat.
3. Put Direct next to your branded searches in Search Console. If both climb at the same time, people are hearing your name somewhere and coming to look.
4. Add “How did you hear about us?” to your demo or signup form, as a free text box. People will just write ChatGPT if that’s where they found you, and GA4 will never show you that.
You probably won’t get every AI visit, but you’ll at least know where to look. Save this and send it to whoever owns your GA4.
