This document summarizes a presentation about A/B testing web pages. It discusses why companies should test pages rather than relying on assumptions, and which pages and elements are most worthwhile to test, such as lead generation forms, buttons, headlines and images. It provides examples of tests that increased conversions by 30-125%. It also offers guidelines for testing, such as running tests for 1-2 weeks with at least 500 visitors, and convincing executives by focusing on return on investment. The presentation was given by Anne Holland and Mike Volpe to marketers.
