Internet Marketing is a work in progress. Many times it seems to change faster than a politician's speech. For instance, there was a time when Hit or Click Exchanges produced good results for those using them. Now however, there are many more effective ways to spend your time marketing. Of course a lot of it has to do with how much money you have to spend. If your budget is small, then things like Hit Exchanges might be something to spend some time with. One of the key factors with using them is having something unique from the mulitude of affiliate sites that are shown on them. If you are able to create your own pages, and have something that would be of interest to the other marketers and webmasters using the exchanges, then it might be worth your while to use them.
