There's lots of well known tools out there to management PPC accounts across different search engines. Just wondering which ones people had tried and found to be user-friendly and effective.
What I'm looking for is software that allows you to manage a keyword inventory across multiple search engines. So you have one interface to manage keywords on Adwords, Yahoo, MSN etc.
I've researched quite a few of the best known solutions and they cost a few thousand dollars a month for managing tens of thousands of keywords. Is there any reasonably priced software out there costing, say, a few hundred dollars a month to manage large numbers of keywords?
