There are many different services that offer some form of traffic exchange. Some require you to click and browse other people's websites. Since this is a requirement of all, your hand will be seen by everyone uses the same system.
Other programs - known as auto surfs - is based on the same idea but instead of clicking on links, the script does it for you. The good thing is, you do not need to browse, or even see a single page to earn "page views". The downside is quite obvious, for there is no guarantee your site will actually be seen, you're only getting automated page impressions.
Another way to exchange traffic with other websites is through so-called Toplists. You simply send visitors to a top list - the more you send, the higher your link will be placed - you get more visitors back.
Another popular method is banner exchange, borderline automated. Often it is scripted, with ways to earn credits much the same as traffic exchanges and auto surfs. But the big difference in the quality of traffic received. Another big advantage is the free exposure you - and your brand - will come from to have your banner viewed over the Internet. It is no coincidence that large companies spend top dollar on making their trademark (s) known.
Is this road of no use?
Well, it can be. Depending on what your site is about, you can get much out of these programs. Advertising a product that appeals to webmasters and website owners, will make it easier to attract new customers, since they are the only ones who use these traffic programs.
If you have a site completely unrelated to the webmaster community, you can advertise your affiliate program if you have one.
For those of you who are not running an affiliate program, and with no products that appeal to webmasters, it's time to get creative.
If you use these "tools" to your advantage, it is possible to extract quality visitors - all except the same amount - rather than simply site views and loss of bandwidth. Read more about converting hits to the visitors of El Traffico.
Are there any risks?
Many contextual advertisers do not automatically accept traffic, some will even terminate your account if you repeatedly send automated traffic to pages with contextual advertising code on it. If you run a lot of traffic to your site, see that you only send it to the sides, without these ads. This is particularly important if you get paid per impression. Nobody wants to pay you for automatic display.
Try to spread the traffic out a bit, not to assign all visitors at the same time. It can and will be a huge amount of page views, if you use autosurfs to directly send traffic to your website. This can slow the site down if you refer them to a "heavy hand".
