Paid advertisement websites are a common way of earning money online.
Bux.to is a site that does just that-it allows its users to make money
simply by clicking on advertisements. That... doesn't seem to make
sense does it? Oh, but it does!

Other websites pay Bux.to to post advertisements to their websites, and
Bux.to pays you to visit the sites. If they didn't pay you, would you
be so inclined to visit the advertiser's site? Probably not. Even if
you did, you probably would only be interested in a few sites anyway.
Paying the users draws users to many websites at a time... then you're
more likely to use their services! If you're using their services, then
it seems that it makes sense to pay you, because in the long run you'd
be paying them.
