A Traffic Exchange is a type of website which provides a service for webmasters in exchange for traffic. It is similar to the autosurf concept with the exception that Traffic Exchanges usually use a manual rotation. A website receives website submissions from webmasters that join the networks. The person who submitted the website then has to browse other member sites on the exchange program to earn credits, which enable their sites to be viewed by other members through the surf system. This increases the number of visitors to all the sites involved.Exchanges enforce a certain credit ratio, which illustrates the amount of websites the surfer must view in order to receive one hit through the program for their promoted website. Many sites offer the ability to upgrade one's membership level for a more equal credit ratio. As the viewers are all website owners or affiliates, it is possible that some might find certain member sites interesting and thus make note of them on their own sites, sending more traffic their way. Most traffic programs also impose a time limit when members are browsing, ranging from 10 seconds to 60 seconds. Some incorporate the use of captcha to ensure user interaction.Almost all traffic programs are free, although many of them offer special features to paid members and offer credits for purchase. Almost all traffic programs encourage users to build their own referral networks, which in turn increases the referrers' amount of credits. The traffic generated in a traffic exchange can be leveraged by using a downline builder to assist the user in building a referral network in the many different traffic exchanges. In practice, traffic exchange programs are generally used by small business owners or marketers who either want free advertising or use the exchange programs for low-budget advertisement campaigns. Also, a small number of users may simply purchase credits because of their typically low price. Some are free, some ask you to pay. Some pay the members just for viewing the pages, while others provide faster browsing and good ratios like 1:1 for upgraded accounts and to make is easier to upgrade they have advertisers that will pay for a paid membership letting the member get better benefits for free. |
