how is it fair to compare bounce rates or time on site?
High bounce coupled with a high time on site is indicative of a user who reads the article and is not merely skimming it, the article provides a value that the user wants to continue interaction with. High bounce with low time on site shows users are just skimming or shallowly interacting with content. Shallow interaction can be a descriptor of low-quality content.
I doubt the money interest on the algo update side of things, but the rise in certain google properties through panda updates is definitely to be scrutinized.
