Is this really worth your money? It's consuming a lot of my time putting a lot of keywords as much as possible but is it really worth the try?
ummmm....that's why google is worth $1xx billion dollars. all the people paying for PPC. they wouldn't be doing that if it wasn't worth their time.
Depends on what you are advertising. Calculate your return on investment and you can answer that question yourself.
I do think its worth it however i also think alot of people are getting ripped of and taken advantage of. Will.
