To add your Google AdWords conversion you need to place the conversion code within the content of the goal page.
On article pages this is done by simply copying the conversion code provide to you by Google AdWords and then pasting it into the article using the “Source” view in the WYSIWYG editor.
Then scroll to the bottom of the html and paste the AdWords conversion code there.
*You can paste more than one AdWords code to a page if you are running multiple campaigns for a single goal.
