Thereās a āsimpleā solution to the decline in the quality of Google Search.
Make a replacement.
It wouldnāt even need to index a fraction of Google Search to produce decent results.
In fact, holding back on what it could crawl seems like a good idea.
In PageRank, the idea was to score pages by incoming link ratio.
What if you factored in reputation? Not like TripAdvisor. More like the degree of separation from a reputable page, and you refused to index low reputation links.
