BidVertiser is good PPC programme

Bidvertiser is different from some other advertising systems in that they will payout to paypal or check. They will also make payments when you earn as little as $10.

Advertisers bid on your site directly, and not based on content or keywords. This way the ads are very specific to your site and clients for maximum click through. As such you don't need much text on your site. Your sites can be all flash based.

The money you get per click is based on the quality and popularity of your site. The more popular and your site is, the more money per click you will get.

Google Adsense is the popular Advertising programme

Google Adsense is the workhorse of the make money online world. Most of the time if you see an ad in a web site it is powered by google. The system is very simple. You put in a nugget of javascript code into your web site. That code automatically detects what your page is about from the text in your site. They are called contextual ads. The code then shows advertising that is related the closest to your text.

The javascript is made for you. There is an easy to use wizard that helps you choose the size and type of ads to show, and at the end presents you with the code to enter in your site. You get paid monthly if you have made a minimum of $100 in money. The issues that some may have with adsense are that you don't know how much you are going to be paid. Google does not declare what the percentage will be.

 
You may have google adsense ads shown with other ad systems as long as they are not also contextual ads. Most web sites use Adsense with other advertising systems to maximize their earning potential
