Score the idea across eight factors: search demand, audience match to buyers, uniqueness, path to product, build feasibility, maintenance burden, link-building potential, and share-worthiness. Scores of 25 or higher indicate a strong candidate; below 15 means reconsider.

Six main types exist: calculators (ROI, savings), generators (templates, policies), analyzers (graders, auditors), testers (speed, validators), libraries (icons, snippets), and interactive educational tools. Choose based on whether your audience needs decisions, creations, evaluations, or checks.

Partial gating is typically the best approach: show basic results free and gate the detailed report behind an email. Fully gated maximizes capture but reduces usage, while fully ungated maximizes SEO value and reach but captures no direct leads.

Build custom when the concept is unique, core to your brand, and you have dev capacity. Use no-code tools like Outgrow, Typeform, Tally, or Webflow when speed to market matters, dev resources are limited, or you are testing a concept.

Common causes include missing SEO keyword targeting on the tool page, no launch or distribution strategy, dominant existing competitors, and insufficient unique value. Recovery requires on-page SEO improvements, supporting content marketing, and product differentiation.

Include only core functionality that does one thing reliably, essential UX with clear input and obvious output that works on mobile, and basic email capture connected to a usable destination. Skip accounts, saved results, advanced features, and edge cases.
