At least knowing what to tell clients with awful CTR helps.
Also, our rep said this Mystery Partner traffic, which should be Content Traffic IMHO, is NOT counted in CTR.
putting search ads into search network changes the reality. for instance, tripadvisor presents way more ads than search results pages do. it also makes it more difficult to find out what converts and what does not.
what other sites are search network?
perhaps we can make a big list of well known sites here divided by sector if G does not want to share?
I hope Mods allow us to post URLs in one particular thread as it would be really useful for WebmasterWorld community.
Let me start with the one mentioned already:
Sector: Travel
Site: tripadvisor.com
