If you have the FHR platform integrated into your web shop, you need to make a query to FHR to display a given page to the shopper. This may include different types of pages, such as: navigation pages, search results pages or product detail pages. Without A/B tests, such a query would return the standard (default) version of the page. With A/B tests however, you would request a variant of that page with the A/B test applied, based on the user's session id. This way, different shoppers would receive different variants of the page, thus allowing you to compare how different variants of the same page perform.
