> Facebook’s daily to monthly user ratio, or stickiness, held firm at 66 percent where it’s stayed for years, showing those still on Facebook aren’t using it much less.

What are the precise definitions of daily and monthly active users? To be a daily user, do you literally have to use Facebook every day for a month?



Daily active users is the number of unique people who showed up in a single 24 hour period. Monthly active users is the number of unique people who showed up at least once that month.

To get the ratio of DAU to MAU, you can either take the average DAU for each day of the month, and then compare that to the MAU, or you can take the DAU to MAU ratio for each day and then average that. They'll both come out about the same (doing it the second way smoothes it out just a bit more because of the loss of precision which makes the month to month comparisons or quarter to quarter a little smoother).


No, it's just the number of users who used it that day, no matter what each of them did on previous or subsequent days.


I am curious what 'used' means. e.g. Does logging into a third party service via facebook login count as 'used' since you technically hit their servers?


No, if it were that tangential, investors wouldn't be reporting it and using it to make buying / selling decisions.


I think you overestimate how deep investors dig. I did find this from a few years ago which contains a bunch of rather fuzzy language: https://www.adweek.com/digital/monthly-active-users-definiti...

My interpretation of that would be that if, prior to that change, you logged to spotify with facebook and didn't uncheck the 'share' button you would have been counted, but after you would not have been.

I do find it rather curious that they simply count any user that logs in and 'visited' facebook. i.e. that no 'actions' need to take place or there isn't any metric for time on site required. Seems rather easy to game that number by just not going after bot accounts.


True, numbers can be gamed.

But at the end of the day there's one number that matters: people click ads and buy products -> companies buy ads and pay fees. And it's been going up steadily for the past decade.

If you strongly believe that you've found an inefficiency in the market please feel free to short FB.


The number shared though is usually a weekly or monthly average.

Otherwise it be easy to game


Is there something that tracks the number of minutes a daily active user spends on the site? I still login to facebook but I barely post on it anymore and spend way less time than I used to a couple of years ago.


They certainly track it, so it may be telling that they are not reporting the trend in this measure.
