Suggest Best AdWords Threads - AKA "Must Reads"

In the next few weeks I'm going to a add a new sticky in this (AdWords) forum that includes links to "must read" AdWords threads that have been posted here over the years. I would like to include threads that are helpful to new and/or experienced AdWords users, do a great job answering common questions, or are just so thought provoking/insightful that they should be read by anyone who visits the AdWords forum.

Post your suggestions in this thread. Three quick pointers;

1. Suggesting your own thread(s) is fine.
2. When suggesting a thread include the reason(s) why you think it should be included. FYI, "it's great" is not a reason
3. Don't suggest garbage - and if you need clarification on what garbage is then you most likely should not be suggesting threads


Thanks!

 

I'm nomination this thread: Guide to Adwords Dynamic Keyword Insertion

DKI has improved my adwords revenue a lot, so for those whom are not using it yet this is a great thread explaining DKI in a very simple way. If you don't understand it after reading this one, you mind as well outsource the job.

 

That's a good one and will without a doubt make the list. Thanks!
