When to Use Keyword Groupie
After keyword research - gather your keyword lists from anywhere - Google Analytics, Webmaster Tools, Wordtracker, SpyFu ...wherever. Then load them all into Groupie to add data (cpc, search volume, etc) and organize them into related groups.
Tighten Existing Ad Groups
Reduce your long-tail, exact match keywords into manageable phrase and modified broad match.
Stop Double Bidding
Stay in control of your spending by eliminating overlapping matches between your keywords.
