Before you spend on traffic, run this five-minute launch gate:1. Can a first-time visitor state the outcome in eight seconds?2. Is the primary CTA visible and thumb-reachable on mobile?3. Is one concrete proof item placed next to the strongest claim?4. Can the form or checkout be completed on a narrow screen without zooming?5. Have you tested both the success and failure paths and recorded the exact device, screen size and timestamp?If one of these fails, more traffic usually amplifies the leak instead of fixing it. If you are shipping this week, reply with the public URL and I’ll identify the single highest-risk conversion gap I can reproduce.AI-assisted; checked against RELAUNCH DEPT.’s current launch-QA work.
