Here's an example of a thing I've noticed:
Without paying too much active attention, I've noticed that a lot of websites that are slop haven't bothered to change the default favicon of whatever framework they use. But specifically WordPress appears to be popular.
I don't know if this would be practical to implement. Perhaps just a simple hash check could be a hint about the quality of a domain. This could be trough a hash lookup for these tiny files.
From what I've noticed, this could filter out a lot of "best [the product category you searched] of 2026" pages that are just a bunch of loosely or unrelated amazon links
