Just curious how many purchases popular posts like this drive on Amazon / affiliate sites. For 10k visits, is it like 1% of traffic? Or more like .1% or .01%?

Just curious how many purchases popular posts like this drive on Amazon / affiliate sites. For 10k visits, is it like 1% of traffic? Or more like .1% or .01%?
