I just built a simple keyword segmentator tool a few hours ago... Basically what it does is takes a list of your keywords, and then segments them into adgroups using your choice of a common word. This will allow you to better target with your ads, get higher CTR (because ads will be more targetted), and you'll be able to keep stats/organization easier. This tool would be for those affiliates who scraped like a bajillion keywords and then just threw them into an ad group, or for marketers who didn't take time to separate their keyword into related ad groups. Feedback welcomed! Tool at http://www.bluebobbo.com/tools/
