Do you see this reflected in higher user numbers coming from DuckDuckGo over time?
I run a website too. Let me check the stats...
So according to Google Analytics over the last 30 days, 0.7% of my visitors came from DDG. Not bad. That is more then half of Bing, from which 1.2% of my visitors come.
Over time, the DuckDuckGo trend does not look as exponential as in their chart though. More like a linear growth that about doubled from early 2019 to now. But that could be due to many factors of course. Blocked analytics being one.
