This is a basic wordpress plugin to add Popupbooster to your wordpress site. It adds the Popupbooster javascript code into every page of your, so you don’t have to code PHP to add it to your templates.
Popupbooster is a popup/overlay tool that features:
<ul>
<li>wysiwyg editor (but also option to mess directly with the html code)</li>
<li>very customizable design/appearance</li>
<li>ctr (click-through rate) tracking</li>
<li>visitor targeting (showing different popups based on search-engine keywords used, landing page, referrer,…)</li>
<li>preview on your site before you put them live for your visitors</li>
<li>media (youtube, flash, …) embedding</li>
<li>very basic visitor info (keywords used if any, referrer, landing page) to aid targeting</li>
<li>… (out of scope to mention it all here, check the <a href="http://www.popupbooster.com" rel="nofollow ugc">Popupbooster</a> site)</li>
</ul>
This plugin is based quite heavily on the Piwik Analytics plugin by Jules Stuifbergen which in turn was based on the Google Analytics wordpress plugin by Joost de Valk.
Please note that this plugin requires a <a href="http://www.popupbooster.com" rel="nofollow ugc">Popupbooster</a> 
that you can get <a href="http://app.popupbooster.com/signup" rel="nofollow ugc">here</a> (free account available).
Future enhancement: who knows, depending largely on what the Popupbooster api will look like.
