Traffic exchanges allow users to earn credits by viewing ads and links on other sites, which can then be used to drive traffic to their own site for free. Some traffic exchanges require waiting through timers or forced views, while others aim to minimize disruption to normal browsing. They are a free way for those with limited budgets to advertise online and can provide targeted traffic for internet marketers. Users can capture leads from their traffic exchange traffic and use them to build email lists or recruit affiliates to sell products. In conclusion, traffic exchanges are services that let webmasters attract more visitors and exposure through earning and spending credits on a network of promotional pages.
