Web content optimization is an important method to push your website to a new high and that is of great concern. Since there are several content designs available for you and it is hard to make decision which one will be favored by visitors, then you should go with A/B testing. That is a practical way to help you make up your mind.

What is A/B Testing?

A/B testing, as its name suggests, is used to test two or more versions of the same object which can be a page design, a product, a post or something else. Both A and B versions are made public thereby leaving a chance for all visitors to make a choice between two options. After testing, the more popular version stays on your site while the other one should be sifted out.
