Design free tool CTAs as natural progression to paid product
The CTA on your free tool should show the logical next step, not just a generic signup link. Frame it as 'You tried X with one thing, what if you could do Y with everything?' This positions the paid product as the natural evolution of what they just experienced, not an unrelated pitch.
When to use
When building free tools or freemium products; when designing upgrade paths from free to paid features
Don't do this
Generic 'Sign up now' CTAs that don't connect the free tool experience to paid product value; pitching unrelated features instead of natural expansion of what user just did
