If your website is an important tool in your marketing strategy, any means of optimisation is welcome. For instance to improve the conversion rate or increase the price of the average basket (performance indicators).
Would you like more potential clients to contact you thanks to the site (on-line form, for instance)? If so, you must at times hesitate when you want to have your site assessed: should you change the design or the content?
AB testing is a method that can be used to compare a version A and B of the design, of one or more pages, by testing them on your site for a specific period. The results obtained will enable you to take the right decision (increase the number of pages seen, better conversion rate, ...).
