I am tracking Adwords performance by measuring (net) sales conversions, (revenue - advertising cost) e.g.
Amazing Widgets $500
Blue Widgets $450
Cerise Widgets $150
Dumb Widgets $45
Eerie Widgets -$20
etc
Rainbow Widgets -$400
In this particular campaign, I have 18 (repeat 18) Ad Groups and each successive one of them performs progressively worse than the previous one. Not one is out of step.
Should I change all keywords to AAAAAmazing Aardvark Aidgets? :)
