Once you activate the Clickbank or the Amazon module, and set your credentials, links will start appearing in your content so you can earn money. The plugin can be downloaded for free from WordPress Plugin Directory (http://wordpress.org/
As it is said in the introduction, if you activate Amazon, Clickbank or Shareasale modules, the plugin will connect to their servers and will get that affiliate links that will match your content. Then the links will be added on relevant keywords, so you can sit back and relax while waiting for the money to come.
Another important feature is the Import/Export function. Now you can save all your links in a .txt or .csv file and select your preferred delimiter. At any point you can import that file into the plugin. This is also nice when you have a long list of link-keywords pair to be added.
Module Support has been added. New functionality can be added or removed trough this new module support. Other developers can build modules for Wp Auto Affiliate Links.
In this version of the plugin we worked at almost all aspects of the plugin. First we dealt with the code. We cleaned the code and re-arranged it into files. Then we moved onto the design side. We completely changed the old school tabbed design into a full WordPress menu category. Many under the hood changes were made to ensure the good functionality of the plugin.
The speed was an important factor when we worked at forth version of the plugin. We implemented some benchmark code into the plugin and made all changes required so the loading speed impact on the wordpress to be minimum.
Link cloaking was also improved, and now it works even if there is no permalink structure set. Keyword suggestions are now hidden and on a keypress they are displayed in a table-like style so you can quickly add them.
The replacement engine was also improved. Now links are not added in H tags. There have been about 100 new updates since version 3.0 . To avoid compatibility issues and conflicts, a big part of the processing ( especially for amazon and clickbank ) is done on our servers.
