I use plausible analytics to measure traffic on my observable notebooks. I did try with GA but it didn't work with Observable's iframe sandboxing. Because plausible is open source, I could fiddle with it a little and could get it to report the top level page user facing URLs instead of the iframe's. Very happy I can get traffic stats from a site I don't own and very happy I don't need user consent because it's GFPR compliant. It tracks just what I am interested... My traffic, and with a little config it excludes my own page views. Great product, perfect for my use case I wish them well.
