I have read the books and I am interested to hear from what people that have had success with either Adwords or Overture have to say. What is the best way to setup/organize the Campaign structure? Lets take a Affiliate program for lets say a SHOE store (I don't promote shoes). 1. I would make a campaign called Shoes - Within this campaign I would divide it up within multiple AdGroups broken down first by Brand. So maybe 500 AD groups with Brands. Secondly by TYPE - 50 AD groups by type of shoe. Third I would research buying keywords such as BUY shoes , Purchase Shoes and put then in separate ADGROUPS. 2. I would research keywords in each group and add about 100-500 per adgroup. 3. ADS PER GROUP and TEST and REPLACE every 5-7 days. What am I missing. This just does seem to be the best way to go about structuring a BIG campaign.
