Getting started with A/B testing
Getting to know page and site analysis tools
Using link analysis tools
In this chapter, we cover the nuts and bolts of A/B testing. We walk you through it step by step and hopefully demystify the process a little bit. We show you how to fix common conversion and usability problems, and introduce you to some page and site analysis tools. Finally, we discuss how to use link analysis tools.

A/B testing is testing the original version of the Web site (A) against the one you made the major changes to (B).
