Hi Kathy,

If you are referring to "surfing for hits" - I wouldn't consider it a business in itself.  But doing this to build consistant ongoing traffic for years to come is a great idea. 

Here is a program that specializes in surfing: http://www.traffichoopla.com/P2.htm?4577 - with weekly testing reports to show which are the best sites to surf on and how to go about it.

Surfing isn't really a business on its own. It's and advertising strategy.

However, carefully planned, it can be a great way to add extra income. I can and have used it to generate money that can be used to boost advertising in other areas, buy in to other programs, etc.
