How does PPC (pay per click) work?

[Omar]

in PPC, you have to click on an ad and not only have to keep open for 1-30 secs, you also need to stay on that page and kinda look at it. If you try to do anything else like checking emails or facebook the time will pause and when you will back on that ad the time will continue from where it was paused. And if you open another ad at the same time, you wont get paid (By the way it depends & varies, but most of them have this rule, one ad at one time)
