Word: Conversion Rate

Definition: The percentage of users who take a desired action.

Thought: A frequently used example of conversion rate when it comes to UX is e-commerce. This would be the percentage of website visitors who buy something on the site. The Neilson Norman Group sums up the power of UX perfectly by stating, "Increased conversion is one of the strongest ROI arguments for better user experience and more user research."

Conversion rate is an important and qualitative way to measure performance over time and put an understandable and quantifiable statistic on the influence of UX practices. There is power in numbers, and strength in research. But remember, with great power comes great responsibility.

Question:  While e-commerce is the typical example of conversion rate, what other types of interactions are easily and effectively measured with this?
