Nielsen Norman Group ( https://www.nngroup.com ) is a good place to look for somewhat similar content. NNG focuses more on user experience, and so their studies are usually based on direct observation of users, rather than large amounts of data gathered through analytics.

Still, it has proven a very valuable resource for me when trying to explain a decision I've made in a new website design. They have many free articles that offer some good insights, as well as some more in-depth reports about specific sectors that will cost a few hundred dollars each.
