Traffic exchanges are becoming a frequent occurence online now, new ones opening every single day. But which ones are going to take off and which ones are likely to struggle is determined largely through how the site is configured. Here are a list of the general problems:

Large amounts of free credits

This will work to get more members but the members are unlikely to use the site much unless you have lots of members veiwing lots of sites. Without members will join and activate, then assign the credits to a site and move on. You often end up with members having rediculous amounts of credits, lowering the number of sites that are seen.

Allowing too many websites

Allowing too many websites is mainly a problem when combined with large amounts of free credits. For example if member get 10,000 free credits for joining and you allow unlimited websites then they assign the credits equally to 10 sites, the pages will be seen once or twice a day. However if you limit the number of websites, each site overall will get more visitors.

I hope these problems outlined above help with people launching traffic exchanges.
