I've been using some copywriting software over the last month. I ran tests using it on one of my top-selling sites, and it has boosted the visitor/sales conversion rate by an amazing 15%.
This has been the highest performing change I've had with the site since it launched in 1999.
I am very impressed, and it takes a lot to impress me.
Have a look at my test results site and see for yourself. I give detailed 'before and after' examples of the rewritten copy... you could even use my samples to improve copy on your own websites.
