BREAKING DOWN 'Monthly Active User (MAU)'

How do some popular websites define monthly active users?

Facebook considers a user to be a MAU if he has logged in and “used” Facebook within the month. “Used” is defined as interaction with the website: liking, sharing, commenting, messaging, clicking through on a link.

Twitter counts users who follow at least 30 accounts and are followed back by at least one-third of those accounts to be active users. The MAUs are determined by counting active users who have signed in within the month.

Google+’s MAUs are those who have an account and user a Google service at least once in the month.
