Google's contextual advertising network. Publishers large and small may automatically publish relevant advertisements near their content and share the profits from those ad clicks with Google.
AdSense offers a highly scalable automated ad revenue stream which will help some publishers establish a baseline for the value of their ad inventory. In many cases AdSense will be underpriced, but that is the trade off for automating ad sales.
AdSense ad auction formats include
cost per click - advertisers are only charged when ads are clicked on
CPM - advertisers are charged a certain amount per ad impression. Advertisers can target sites based on keyword, category, or demographic information.
AdSense ad formats include
text
graphic
animated graphics
videos
In some cases I have seen ads which got a 2 or 3% click through rate (CTR), while sites that are optimized for maximum CTR (through aggressive ad integration) can obtain as high as a 50 or 60% CTR depending on
how niche their site is
how commercially oriented their site is
the relevancy and depth of advertisers in their vertical
It is also worth pointing out that if you are too aggressive in monetizing your site before it has built up adequate authority your site may never gain enough authority to become highly profitable.
Depending on your vertical your most efficient monetization model may be any of the following
AdSense
affiliate marketing
direct ad sales
selling your own products and services
a mixture of the above
