Twitter | 2019 Annual Meeting of Stockholders
The numbers of mDAUs presented in our annual meeting materials are based on internal company data.
While these numbers are based on what we believe to be reasonable estimates for the applicable period of
measurement, there are inherent challenges in measuring usage and user engagement across our large user
base around the world. Furthermore, our metrics may be impacted by our information quality efforts, which
are our overall efforts to reduce malicious activity on the service, inclusive of spam, malicious automation,
and fake accounts. For example, there are a number of false or spam accounts in existence on our platform.
We have performed an internal review of a sample of accounts and estimate that the average of false or
spam accounts during the first quarter of 2019 represented fewer than 5% of our mDAU during the quarter.
The false or spam accounts for a period represents the average of false or spam accounts in the samples
during each monthly analysis period during the quarter. In making this determination, we applied significant
judgment, so our estimation of false or spam accounts may not accurately represent the actual number of
such accounts, and the actual number of false or spam accounts could be higher than we have estimated.View entire presentation
