AdSense is an ad serving application run by Google Inc. Website owners can enroll in this program to enable text, image, and video advertisements on their websites. These advertisements are administered by Google and generate revenue on either a per-click or per-impression basis. Google beta tested a cost-per-action service, but discontinued it in October 2008 in favor of a DoubleClick offering (also owned by Google).
It is simplest affiliate program ever. Even personal websites and blogs can display advertising without directly dealing with adverstisers.
You simply put AdSense Box or Banner frame on your website (you have to register to AdSense, it’s free, and setup the ad box which literary is taking 2 clicks). Then you can select advertisers or keywords filtering the content of the ads displayed in that Box on your website.
Money come to you simply when someone will click on the ad in your AdSense Box on your website and will purchase something from that advertiser website.
So for example if you have a blog about holidays, you can build such blog with travel agent ad or hotels, and you have big chance that someone will book his ticket via this link, don’t you think?
But also there is other way, AdSense for domain. And this is much better business. From experience I would say it’s more befeficial. That is why many people are using domain registrar robots. For example you have domain name which is in google search results. When your domain name registration expires and you didn’t buy backorder for domain they gonna buy your domain name and put google ads on it. As google search results will display old content is search results for some time, it will link to new content. So they can make quite good money on your domain name.
Well try it yourself, it’s free and very easy – click here to start.
