Meta descriptions are between 120-160 characters

The SERP description snippet is your only free 150-character ad copy above the fold for an organic listing. A 40-character description leaves empty space that Google may refill with scraped text you did not write; a 240-character description gets truncated mid-sentence, often on a comma or preposition, so the reader never sees the call to action. Both failure modes leak clicks to competitors whose descriptions fit the viewport cleanly.

Write descriptions in the 120-160 character band. Fit a claim plus a differentiator plus a verb — not a list of keywords. Check the length programmatically in tests or in the CMS field.

// app/about/page.tsx — 128 characters
export const metadata = {
  description: 'Learn about our team, our mission to improve vibe-coded projects, and how AuditBuffet helps developers ship with confidence.',
}

For dynamic content, clamp the string in generateMetadata with .slice(0, 157) + '...' so CMS content cannot overrun the limit.
