Don’t Use Cost Per Click Services Alone: Get Help from Online Services

If you’re an expert in cost per click marketing, directly advertising on Google, Ask, Yahoo, Live or some other service is not a problem. However, if you don’t know what you are doing it’s a worth while investment to get some help.
About 2 weeks ago, I purchased a $50 per day advertising package through Google and ended up paying a lot more than I wanted and probably wasting some money in the process.
Services that you could consider, which give you hand holding are services like Earthlink’s newly announced Traffic Builder and’s Search Light.
The benefit of these services is that they give you one monthly fee and guarantee you a certain number of click throughs to your site a month. Of course they can’t guarantee sales but click throughs.
The other benefit of these services is that you can pay one fee and be listed on a number of CPC search engines and affiliated web sites.
I found Google’s chat tool and email support to be very good.
