Someone in this thread mentioned AdSpyPro as a good alternative to Google Cash Detective and all the rest of them... I am just wondering what it is exactly they do? The landing pages for the programs don't really tell much. AFAIK they monitor the ads for the keywords you enter, but monitor how? To what end? Also a search of AdSpyPro yielded nothing here? Anyway, I am curious as to whether they are worthwhile, or would I be wasting my time?
