I have been playing around with their keyword optimization tool for 3 days now, and the results look impressive. You get to choose up to 5 keywords on your own, so it’s like choosing your own ads. Sometimes their system doesn’t seems recognize the keyword/phrase (lack of advertisers?), but the thing does work when you got the right keywords. I’m making about $10 a day (0.9% CTR), and it’s getting closer to my adsense earnings now. Did anyone try to using their tool?
The keywords will depend on what kind of website you plan to run, so it will be different for everyone. There are some keywords that are better than others, but I would just like some comments about their tool, cause i find it works well with what i want it to do. If anyone has used it or can try it out and provide comments that would be great!
