>The comments here that PageRank is Google's secret sauce also aren't really true - Google hasn't used PageRank since 2006.

That's quite a claim considering they were reporting PageRank in their toolbar until 2016, and toolbar PageRank was visible in Google Directory until 2011.

Are you talking about PageRank from the original patent?

It is a seemingly incorrect claim. Google has semi-recently, publicly said they still use PageRank as one of their signals.

They replaced it in 2006 with an algorithm that gives approximately-similar results but is significantly faster to compute. The replacement algorithm is the number that's been reported in the toolbar, and what Google claims as PageRank (it even has a similar name, and so Google's claim isn't technically incorrect). Both algorithms are O(N log N) but the replacement has a much smaller constant on the log N factor, because it does away with the need to iterate until the algorithm converges. That's fairly important as the web grew from ~1-10M pages to 150B+.

This is the weird thing -- it feels smaller. Back in the early 2000s it really felt like I was navigating an ocean of knowledge. But these days it just feels like a couple of lakes.

(also, I'm pretty sure it was billions already quite early on?)

So what's the name of the new algorithm?
