Adwords Split Testing
Google Adwords is a pay per click program that allows you to put ads on Google, other search engines, and even “non-search” websites. The object is to write a targeted ad that gets a lot of clicks. The more clicks you get, the less you pay for each click.
One way to improve your ads over time is to split test them. You can run two or more versions of your ad and have Google show each ad approximately the same number of times. Note: you have to go into your campaign settings to tell Google to show your ads evenly instead of optimizing for you.
