What it does
Ideas for a free calculator or small tool that brings in leads and search traffic, plus a plan to build it and a check that it is worth the effort. It asks about your product, buyers and goal, then lists tool types that fit, such as calculators, generators, graders and checkers. Each idea is tested against four rules: it solves a real problem, it connects to what you sell, it stays simple, and expected lead value beats build and upkeep cost. For the winner, it covers the page, the data capture, how people find it and what happens after they use it.
