Hard to test cleanly, for exactly the reason you mention. What I’ve noticed is pages that get discussed tend to get crawled faster and more often. Whether that’s a ranking factor or just faster discovery, no idea.
@marta_links that’s a fair point, I didn’t split it by whether the linking page gets traffic. Going to pull that from Ahrefs for the 15 pages this week and see if it explains it better than the link type.
