Interactive Calculators and Micro-Tools
A free tool usable without registration: a calculator, configurator, self-assessment, or converter that answers a specific practical question.
Analogy Mental model
The free scales outside a pharmacy. People come back to use them, and no chat window can replicate standing on a machine.
In practice What you actually do
A simple interactive tool is now an afternoon of work, so the barrier is imagination rather than engineering. A logistics company shipping to the United States can publish a volumetric weight and duty estimator; a software company can publish a pricing configurator.
Where people get burned Pitfalls
The tool alone is not the content. Beneath it, publish the formula, the reference table of parameters, and the questions people ask, because the interactive part serves visitors while the static part is what gets retrieved and cited.
