I love that they make their traffic numbers available. I have been using ddg and graphing/predicting the next days traffic since March here: https://qunc.co/ddg.
Definitely a different trajectory since late summer.
I don't want to hijack or anything, but just want to also link to a project I did that also looked at these ads and lets you browse/categorize them interactively: https://qunc.co/russia_facebook_project/
Some stats about the data set:
There were 3,419 ads.
They had approximately 40 million impressions.
Approximately 3.7 million clicks.
And, surprisingly to me, cost only around 117,000 USD in total
Definitely a different trajectory since late summer.
