Autotaalglas.nl is a well known windshield repair company in the Netherlands. Over a period of a year we redesigned and redeveloped their website doubling their online conversion in the first 2 months after launch. In this talk I will use Autotaalglas.nl as a case study to illustrate the importance of good UI and UX for a succesfull website. Running WordPress as a CMS has many advantages but it is not automatically making your website a great website. How did we achieve a doubling of conversion and what are we doing to hold on to the conversion increase? Knowing that on average a car owner has a windshield chip or crack once every seven years you will understand that it doesn’t make a loyal customer. How to keep developing the platform and giving the client an advantage over their competitors? By the time WordCamp Barcelona takes place we are implementing a new feature that connects the website to the planning tool of every repair shop to show availability.
