WordPress.org

Installation is easy

1. Upload the headline-split-test folder to the /wp-content/plugins/ directory
2. Activate the plugin through the 'Plugins' menu in WordPress
3. Enter alternate headlines in the alternate headline section whenever you create a new blog post
4. If you want to change our test for statistical significance, you can edit that in the "Headline Split Tester" options under the Settings menu.

This sometimes conflicts with social media tracking systems that (foolishly) use things like the Post title rather than the GUID to track activity around a post. If this is a problem, go into the settings page in your admin screen and you can configure it to not use the alternate headline on the page, only on the link to the page. This means that when a post wins, you would be best served by changing the post title, although that might mess up your social media mojo as well. Alas.
