I think they have something better - “link rank” which essentially takes into account the quality of backlink.

I believe it is nuanced enough to have different rank per “topic”, or “keyword” etc. but admittedly just kinda guessing from the outside.

The last time I tried to build something like this I realized it’s useless without first having a gigantic amount of data already crawled. When I started crawling I realized I would never catch Google. I think without Wikipedia the LLMs might have taken 10 more years to surpass them.

I don't know how good it was, but sentiment analysis was definitely a thing pre-ChatGPT.
