Copy and paste this into your v0 chat exactly as-is.
Regenerate my v0 component / page with these fixes applied: Add a custom 404 page 1. Create app/not-found.tsx with a helpful 404 page that links back to the homepage.
Why this matters
About 1-5% of page loads hit a 404 on most sites (typos, stale links, Googlebot discovery errors). A default bare "404 Not Found" bounces 90%+ of those visitors.
A custom 404 with search and a few popular links keeps users engaged and preserves SEO value — they do not leave Google's "dwell time" signal tanked.
