How can I explain tracking code in First Touch Channel = SEO?
Dear Community,
I have troubles explaining our user the existence of tracking code in First Touch Channel - SEO. I understand persistence of Tracking code. I understand why there is a tracking code in Last Touch Channel - SEO. But First Touch Channel should be the first channel of the visit, so in theory SEO should be clean.

And yeah, amount of visits from SEO/FTC is significantly lower but they are still there...
Our SEO in processing rules is configured to matches natural search engine detection and tracking code does not exist.
Could you please help me understand it?
