That’s some really obnoxious writing, somehow even worse than the usual AI spam (although this also reads like co-written by AI). Here’s the cleaned up version:

I built 160+ micro calculator tools across finance, math, health, fitness and more. I did the keyword research after and the data genuinely surprised me. There were 3,600 keywords total across the calculator hub. The estimated traffic potential is 341 million per month. The average keyword difficulty is 33. 1,784 of all the keywords sit at an easy KD of under 30. That means that 50% of the entire set have low competition. Small boring tools with exact match domains are one of the most underrated SEO plays.

I guess congrats to the author for saving 30 seconds by leaving out half of the words that can technically be inferred.
