Be The Bot

Have you ever been googleing something, and you see exactly what you need in the preview, but when you click the link it doesn't show you what you want to see? This is because the owners of the site are trying to trick you into buying something, or registering.

When Google visits the site, it gives something called a 'header.' This header tells the site who the visitor is. Google's header is 'Googlebot.' The programmers of the site check to see if the header says 'Googlebot,' and if it does, it opens up all of its content for only Google's eyes. Now, all you have to do is trick the site's headers, into thinking that you are Google.
