If you don't know what you're doing when it comes to running a Pay Per Click (PPC) campaign, it will cost you... a lot. It's so very important that you learn how works. There are a lot of variables that come into play when you set up an Adwords campaign, it is not a couple clicks and watch the traffic flow, far from it. You need to take some time, do some testing and repeat until you've got your campaigns dialed in.
Of course, if you have the budget, you can hire a firm to manage your campaigns for you. There are many places that will do this full time for you. They can set up all your campaigns, write the ads, adjust your daily budget, find the keywords, etc. It's not cheap but if you have more money than time it may be a good option for you.
