Understanding “Conversion” vs “Conversion Rate”

In the context of website marketing, “Conversion” refers to a specific visitor action that aligns with the goals set by a website operator.

  • Whereas completing a registration form requires more effort and more information – this is a strong indicator that the leads are interested in what you are offering.
