Need information about pay per click....

Hello everyone my question is how pay per click works? What the exactly process by which we pay for that or we earn with that?

PPC. An advertising service that search engines provide that allows you to bid on keywords in order to display your adverts. Say you sell Nokia cell phones, one of your keywords would naturally be "nokia cell phone". Whenever someone searches for that keyword, your ad may be displayed. Should that person see and click your ad, you would pay a certain amount which depends on your ad's quality, your bid and the next advertiser's bid and ad quality. That's obviously where the term pay-per-click comes from: you pay only when someone clicks on your ad.

You mention earning money from PPC. That's when you as a site owner displays such ads. For doing so, the search engine pays you a portion of any click revenue coming from your site.

Have you considered using Google to get an answer?

I was wondering though, if you own a website, how can you get "customers" who will be paying you for "pay per click"?

Do you have to go and search for them, or are there any websites/ companies who specialise on this and you can just register with them and they will do the rest?

See the section called Ad-Sense.

And for ****s sake do some research before you post. You obviously aren't even trying so very few people will bother to help you.
