I could not agree more with you Charles. Testing your sales copy is very important and your affiliates will appreciate a higher converting copy. I test my copy with Google Website Optimizer, its really a great tool.

Many people have Google Adwords accounts, but what they don’t know is that with every Google Adwords account, you get a free tool called Google Website Optimizer.

If you have used Adwords before, you already know you can have multiple ads within the same campaign, and then have Google rotate the ads to see which one performs better. This allows the user to see which ad is converting at a higher rate. The user can then delete the ad that did not perform well and create a new ad in an attempt to beat the
current top-performing ad.

The user can do this 10, 20, or even 100 times until they believe they have the best ad possible.

Google Website Optimizer does something very similar, but instead of with text or image ads, it tests your whole website.

For example, you can test different headlines on your website, maybe change some bullet points, maybe you want to change an image, or set your website optimizer to show different variations of all three.

This allows you to see which combination of the different variations you are running performs the best.

This is a great tool and its free, so test your sales copy, you may just double your sales with a few tweaks here and there.
