Website traffic from manual surf exchanges

Doing a search on google I came across manual surf exchnges. So what are manual surf exchanges. The way it works, you earn credits for viewing someone elses website and you then use those credits to display your own site. Websites are displayed are a set period of time, usually between 20 and 30 seconds. After this period you will need to click a verification button to move to the next site. The verification button will be one of say 4 links with the question 'Please click the number 8' or 'Please clisk the hightest number'. These verification buttons are to prevent cheating of the program where a software program could be used to move to the next site. This ensures that real people are viewing the websites.

This is a really tiring way to get traffic and all this clicking could give you cramps in your fingers. The alternative would be to buy the credits instead, but you must consider what type of people are viewing the sites. Most are just clicking away to get as many credits as possible to show their own website and don't pay much attention to what they are viewing. Many of the sites displayed are referral links to other manual traffic exchanges because by referring otheres to a manual traffic exchange you can earn credits for websites they view. I suppose for some the insentive is that they can sell their credits back to the website owner or other users and so make a small profit.
