Built 160+ micro calculator tools across finance, math, health, fitness and more. Did the keyword research after and the data genuinely surprised me.

3,600 keywords total across the calculator hub. Estimated traffic potential of 341 million per month. Average keyword difficulty of 33.

1,784 of those keywords sit at easy KD under 30. That's 50% of the entire set at low competition. Small boring tools with exact match domains are one of the most underrated SEO plays
