    Nice article. I’m always looking for new data services. I have been a loyal SpyFu user for years. How do these services compare? Curious that you did not mention them in this article. Also.. nice to meet another Ellis… hey.

    John, are you asking the difference in SpyFu vs the other three? So…just for the record, I LOVE SpyFu and it is one of my favorite tools for doing competitive keyword research for PPC. The one overlap for all four tools is competitive information on text ads. But there is a huge difference in what makes a text ad successful in search and what makes a text ad successful in display. That’s where the software programs split off. SpyFu only shows competitive information for text ads in search. The other three only show text ad results for display.

    FYI these all cost money, and a ridiculous amount at that. Good article though

    I know WhatRunsWhere.com offers a 7 day trial. AdBeat.com will sometimes offer a trial or special offer but it’s usually through a guest webinar (you might set up a Google alert to watch for offers).
