Hi all,
I was wondering.
If i find an offer i am interested in. Is there a way to find out what types of media are other affiliates running currently for that offer?
Is there a way to "spy" the competition ?

Of course.
This is called competitive intelligence.
Google/search for WhatRunsWhere, AdBeat, I forget the other ones.
This kind of data is very powerful in the right hands but can be overwhelming to digest for a newbie, and is always going to be expensive due to it's value.
I see.
So no free tools around for that, right ?
Well, you can use sites like SimilarWeb, but you're not going to get the kind of data that tools specifically focused on advertising intelligence will offer.
