Well, HITS is applied after you’ve already selected a subset, at response time; so, if you didn’t select s good subset (and AV often didn’t) then picking the most promising out of that subset is not as helpful.

Pagerank is essentially a “universal authority score” (in the HITS terminology), and it worked well because at the tine you didn’t have pages that were authority for one subject and spam for another. You do now - which is why pagerank is now one signal out of 200, even though it was sufficient on its own 20 years ago.
