Over the last few weeks, we’ve seen inaccurate data and graphs circulating on social media channels regarding Stack Overflow’s traffic.

Let’s start with why the data in the graph that’s circulating is inaccurate. There were two changes we made over the last year that impact how we measure and report traffic on Stack Overflow. Both were important and necessary steps to meeting the privacy needs of our users. 

First, we recategorized our Google Analytics cookie. That was completed in May of 2022, and resulted in Google Analytics reporting on fewer visitors’ site activity.
