I run a very successful online business from home and finally made the decision to use PPC to drive more traffic to my website. While the AdWords interface is not that difficult to learn and understand, I realized to get the most out of your advertising dollars you need to spend several hours a day working with it; it's definitely not a set and forget type thing. While I did have success, since I am a one man team, I could not afford spending this much time on it and thus decided to reach out to a PPC management company and I am so happy that I did. ROI PPC really knows their stuff and understood my needs quickly. They have been running my AdWords account for over 3 months now and my return on investment is very satisfying. Yes, I have to admit they know a lot more tricks than I do and for the same amount of visitors per month my costs are way down. I recommend using these guys to anyone.
