I have a PPC account with YSM & MSN AdCenter as well as my Adwords account, but - I'm still in the process of building my adgroups and adding keywords with all 3 of them! I'm becoming a little confused, doing all 3 at the same time: - Should I get Google all sorted first and then move onto YSM and then MSN? - Would you use the same Ad Group for each PPC engine, with the same keywords (where applicable) in each Ad Group? - When split testing would you use the same headings, ad body & landing page for each PPC Ad Group in each? For example, have the Ad Group 'Red Widgets' in Adwords split testing the same ads, as what are in the MSN 'Red Widgets' Ad Group or take the opportunity to test more ads and get more info on which ads work and which don't? - If, in Adwords, I was to include the 'Search Network' (as I currently only have 'Google Search' checked), is it simple to find out from the reports if this is a profitable move or not? I.e find out how much traffic & conversions are coming from the 'Google Search' vs how much is coming from the 'Search Network'? I'd be willing to give it a 'trial run' if the answer is yes. Many thanks in advance, I'll get back with more questions if and when they come to me.
