Free micro-tool as standalone lead magnet
Build a free, no-login utility tool (calculator, validator, generator) related to your core product to drive organic signups at scale.
Why this can grow a startup
Users search Google for free tools to solve a specific task. A well-built micro-tool ranks fast for "free [tool] calculator" keywords because competition is low. Unlike PDF lead magnets, tools deliver immediate utility, so visitors return and remember the brand. Each return visit is another chance to convert to the paid product. One good free tool can drive hundreds of signups per month with zero ad spend.
