I’ve released version 1.1 of the Embed Script WordPress plugin.
Version 1.0 gave you the possibility to add scripts to the end of the ‘content’ of any single page/post. The new version gives you the possibility to add scripts to the beginning of the ‘content’ as well.
This means that the Embed Scipt WordPress plugin has become not only the perfect solution for your adding your Google Adwords to your WordPress site, but also for adding your Google Site Optimizer codes and split test your landing pages!
