A Search Engine Watch Forums posts asks why are we limited to only 25 campaigns within Google AdWords? In response to that question, Chris_D, SEW Forums moderator explains that 25 is plenty and you should structure you campaigns differently. Use adgroups to fulfill your requirements, as he explains by this example:
Assume up to 25 'products' & assume main cost control is required by product; secondary cost control is by adgroup bids1. set campaigns = products 2. set adgroups = product derivative (under campaign) 3. duplicate adgroup - one for search, one for content, with negatives for search - to provide secondary cost control:
Your Account Campaign 1 Widgets -> Campaign 1 - Widgets -> Adgroup one -> blue widgets search -> Campaign 1 - Widgets -> Adgroup two -> blue widgets content -> Campaign 1 - Widgets -> Adgroup three -> red widgets search -> Campaign 1 - Widgets -> Adgroup four -> red widgets content -> Campaign 1 - Widgets -> Adgroup five -> green widgets search -> Campaign 1 - Widgets -> Adgroup six -> green widgets content
Campaign 2 blodgets -> Campaign 2 - Blodgets -> Adgroup one -> blue Blodgets search -> Campaign 2 - Blodgets -> Adgroup two -> blue Blodgets content -> Campaign 2 - Blodgets -> Adgroup three -> red Blodgets search -> Campaign 2 - Blodgets -> Adgroup four -> red Blodgets content -> Campaign 2 - Blodgets -> Adgroup five -> green Blodgets search -> Campaign 2 - Blodgets -> Adgroup six -> green Blodgets content
Excellent, easy to understand, example.
