pagerank for my Obsidian notes

Brian Hicks, January 17, 2023

I recently learned a little more about how the Pagerank algorithm works. I thought it was cool, and it made me wonder what the ranks for my Obsidian vault looked like, so I built a little tool. It's fairly simple: it just parses [[links]] out of the vault with a regex and then uses the simple-pagerank crate for Rust to calculate the ranking.

For my vault, the most centrally connected node is my employer. It's the top node by quite a lot (with a score of 4.9), followed by the town where I live (2.0), then members of my family (around 2) and notes on projects I'm doing and tools I use (around 1.) This makes a lot of sense to me; I primarily use Obsidian as a way to keep a work log and write about things related to that, as I wrote about previously.

If you'd like to try this for yourself, you can get the code at, although you'll need to have either Nix or Rust installed in advance. If you decide to try it, let me know if you find anything interesting!

If you just have questions about this, or anything I write, please feel free to email me!
