A webmaster has a website with following text:
TrueView Traffic provides its users with the ability to control the quality of their traffic. Users can submit questions about their sites that surfers have to answer correctly to earn credit for viewing the site. In addition, users can earn credits by reviewing other members' sites.
After 20 secondes the there are 4 surfbar question, only 1 is correct.
Only than the webmaster had a true-view visitor.
So if the ability to control traffic quality is the webmaster's selling point,
the question bar could ask
TrueView Traffic provides its users with what?
1: nothing 2: just traffic 3: just targeted traffic 4: the ability to control the quality of their traffic
Only those who got the message count as visitors,
so imagine you bought thousand.
