Keep everything checked

Testing your site provides 2 benefits. It allows you to find areas of your site that are leading to low conversion (or areas that need optimized conversion) as well as making sure that nothing is breaking an interrupting the sales process. Test your site as much as you can to ensure a smooth transition between landing on the page, finding a product and making the purchase. You will probably need to enlist the help of a site like digivante.com, as you will need an in-depth knowledge of analytics, but it will be well worth it.
