Random question -- of all the sources you work with, which ones are the most annoying to track?
I don't mean ones with NO tracking, rather ones where its a pain in the ass to use server-to-server tracking, e.g. no postback URL but complicated API setups to make it work.
I'm working on some of these annoying issues and wanted to check in with the community -- complain away!
Yahoo Gemini / Verizon Media is one of them.
All they provide is a tracking script that needs to be placed on the thank you page, while it is necessary to insert the product ID and other values dynamically to properly track results.
So far haven't found any possible alternative to their tracking script.
Might be possible not to be an option out there, since they have both view-through and click-through conversion attribution.
