Above the Fold
A term traditionally used to describe the top portion of a newspaper. In email or web marketing it means the area of content viewable prior to scrolling. Some people also define above the fold as an ad location at the very top of the screen, but due to banner blindness typical ad locations do not perform as well as ads that are well integrated into content. If ads look like content they typically perform much better.

Absolute Link
A link which shows the full URL of the page being linked at. Some links only show relative link paths instead of having the entire reference URL within the a href tag. Due to canonicalization and hijacking related issues it is typically preferred to use absolute links over relative links.
Example absolute link
<a href=”http://seobook.com/folder/filename.html”>Cool Stuff</a>
Example relative link
<a href=”../folder/filename.html”>Cool Stuff</a>
AdCenter
Microsoft’s cost per click ad network.
While it has a few cool features (including dayparting and demographic based bidding) it is still quite nascent in nature compared to Google AdWords. Due to Microsoft’s limited marketshare and program newness many terms are vastly underpriced and present a great arbitrage opportunity.

AdSense
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

AdWords
Google’s advertisement and link auction network. Most of Google’s ads are keyword targeted and sold on a cost per click basis in an auction which factors in ad clickthrough rate as well as max bid. Google is looking into expanding their ad network to include video ads, demographic targeting, affiliate ads, radio ads, and traditional print ads.
AdWords is an increasingly complex marketplace. One could write a 300 page book just covering AdWords. Rather than doing that here I thought it would be useful to link to many relevant resources.
