WordPress Headline A/B Tester

We just wrote a new, free WordPress plug-in to rapidly optimize blog post titles:

This plug-in allows you to enter an alternate headline for every post on your blog. The headlines are then randomly alternated on your website until a certain number of “headline views” has been reached. At that point, a “winning” headline (as determined by the number of people that have clicked on each headline to date) is determined and that headline is shown going forward.

We would love feedback.
