Want to setup Google re-marketing and add the remarketing code to a wordpress blog?
It’s very easy, but not very well explained. Simply, in WordPress go to Appearance, Editor. Select the footer.php and insert your Google code before the </body> tag.
How to generate & use this remarketing code is explained in Googles help page here: http://support.google.com/adwords/answer/2454064?hl=en&from=166488&rd=1
As a general tip as advised by Google, add the code to your entire site and start capturing traffic information. Later, you can slice and dice the list data based on your different website URLs (pages) and start targeting some ads to these visitors.
