Greg,
Wow, that’s *really* unusual to make money on a keyword that includes the word “freeâ€!
Instead of just removing free as a negative keyword in your campaigns, what about actually adding keywords like “free online event registration†and putting them in their own ad group with their own special ad targeting the freebie-hunters?
By having these KWs grouped together into a special ad group, you’ll be able to see – at a glance – whether these freebie keywords as a group are profitable for you. Or maybe you’ve already done this!
In any event, thanks for reading and thanks for your great comment!
