Traffic Exchange

People who have been exposed to the world of earning online know importance of traffic and people clicking on your links, whether they may be referral links, affiliate links, or your own site. If you're running a website or posting your referral links, I would like to recommend the following websites to increase your traffic. All of them are free to join.
The benefit with manual traffic exchange is that it increases your pagerank and Alexa rankings by boosting the number of visits to your site.

LinkReferral.com
LinkReferral.com is a site that is unlike many traffic exchanges. It gives out a lists of websites for people to click on according to what is interesting to them, and does not give it out on an automated basis. Psychologically, that lets the user check out the website more seriously than that of an autosurf.
