Introduction

Most websites continue to struggle with increasing their online conversion rates.

On average, an e-commerce store converts around 3% of its traffic into customers. The remaining 97% of the visitors leave the website without ever placing an order.

Other types of websites struggle with conversion as well. On average, a lead generation or subscription websites convert around 15% of its traffic into customers. The remaining 85% leave the website without ever placing an order.

If you are looking to increase your website conversion rate, you will have to conduct AB and multivariate testing. The problem is that most testing programs start without any planning and thus fail with the first 6 months.

We know this first hand because we have been helping online companies conduct testing for over 12 years. Our goal from this guide to help you with a good introduction to multivariate and AB testing. We will continue updating the different chapters in the book on regular basis, so if you have comments or feedback, please let’s know (@invesp).
