@@ -11,10 +11,10 @@ Wagtail Experiments
 This module supports the creation of A/B testing experiments within a Wagtail site. Several alternative versions of a page are set up, and on visiting a designated control page, a user is presented with one of those variations, selected at random (using a simplified version of the `PlanOut algorithm <https://facebook.github.io/planout/>`_). The number of visitors receiving each variation is logged, along with the number that subsequently go on to complete the experiment by visiting a designated goal page.

 This module supports the creation of A/B testing experiments within a Wagtail site. Several alternative versions of a page are set up, and on visiting a designated control page, a user is presented with one of those variations, selected at random (using a simplified version of the `PlanOut algorithm <https://facebook.github.io/planout/>`_). The number of visitors receiving each variation is logged, along with the number that subsequently go on to complete the experiment by visiting a designated goal page.

 **A/B testing for Wagtail**
 
 This module supports the creation of A/B testing experiments within a Wagtail site. Several alternative versions of a page are set up, and on visiting a designated control page, a user is presented with one of those variations, selected at random (using a simplified version of the `PlanOut algorithm <https://facebook.github.io/planout/>`_). The number of visitors receiving each variation is logged, along with the number that subsequently go on to complete the experiment by visiting a designated goal page.
