Recently I was given the opportunity to manage someones Google Adwords Account.
As I was getting more into looking at the different Campaigns and Adgroups I released that I did not know some of the terms that they were referencing.
I started searching and I found this SEO Glossary that was able to help me out.
Not only did I find the terms that I was looking for but saw some others that I did not know existed.
It is a good reference to stay up on your Search Marketing terms.
