Conversion rate

Conversion rate is almost a self-explanatory term, but when benchmarking conversion, it’s important to consider the denominator. Are you dividing sales by number of unique visitors or visitor sessions?

In Google Analytics, which can be considered the standard reference sales are divided by number of sessions. E-commerce Conversion Rate is defined by Google as:

“The ratio of transactions to sessions, expressed as a percentage. For example, a ratio of 1 transaction to every 10 sessions would be expressed as an Ecommerce Conversion Rate of 10%”.

This is E-commerce conversion rate. For other businesses, conversion to lead is used.

See the Smart Insights digital marketing conversion rate benchmark for examples of different types of conversion rates including business-to-business.
