I'm doing adwords for over 3 years now and currently run 30 concurrent campaigns for my own- and client pages in the UK. All making decent money, so no problem so far... However, there must be more senior advanced material out there in form of books / ebooks / other material etc. (I know this post will trigger loads of affiliate links to obscure ebook pages). Nonetheless there may be some senior fellow adwords experts in here who actually know advanced information sources. Over the years I read pretty much all adwords books you can purchase on amazon, perry marshall's definete guide (incl. the latest 2010 version), the affiliate black book, adwords black book, Ad Infiltration, Adwords180 and others. I am particularly after more advanced techniques on trademark usage variations, general psychlogical incentive buy/purchase keywords, targeted placement content network strategies (I implemented some of my own - takes a lot of research), cutting cost per sale strategies etc. Any direction on that would be appreciated. Money for such advanced information is not a concern, but again I won't even consider buying anything of a flashy little minisite, so save your time by not posting affiliate links. Feel free to post or PM Cheers M.
