Score the idea across eight factors: search demand, audience match, 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: calculators (ROI, savings), generators (templates, policies), analyzers (website graders, SEO auditors), testers (speed, meta tags), libraries (icons, snippets), and interactive tools (quizzes, playgrounds). Choose based on whether your audience needs decisions, creations, or evaluations.

Partial gating is typically the best balance: show basic results for free and gate the detailed report behind an email. Full gating maximizes capture but reduces usage and SEO value, while ungated tools maximize reach and links but capture 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 matters, dev resources are limited, or you are testing a concept before committing engineering time.

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

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