At its most fundamental, CRO means figuring out what users are looking for when they arrive at your site and then giving that to them. CRO takes many different forms, based on the KPI you’re trying to improve. Sometimes this involves making your call-to-action more apparent or placing it on a traffic-heavy (but under-optimized) page. At other times this means removing or relocating unnecessarily complicated or time-consuming steps from your conversion funnel, as the added friction can prevent a conversion from ever happening.
CRO is the method of using analytics and user feedback to improve the performance of your website. CRO can be used to improve any metric on your website that’s important to your business–often called key performance indicators (KPIs)–that you’re trying to improve, but it’s often associated with acquiring new customers, registrations, downloads, etc. Put another way, it increases the percentage of website visitors who experience the “aha moment” (or the must-have user experience) that turns passive browsers into valuable conversions.
