Rule Details

Every page should tell search engines and users what makes it unique. When multiple pages share the same meta description, Google's snippet guidance (opens in new tab) often leads Google to rewrite the snippet, creating the same ambiguity you see when titles are not unique sitewide.

Code Examples

❌ Avoid — same description on every page

<!-- Homepage -->
<meta name="description" content="Acme Corp — Building better products.">
 
<!-- /products page — duplicate! -->
<meta name="description" content="Acme Corp — Building better products.">
 
<!-- /contact page — duplicate! -->
<meta name="description" content="Acme Corp — Building better products.">

✅ Correct — unique description per page

<!-- Homepage -->
<meta name="description" content="Acme Corp builds enterprise project management software trusted by 10,000+ teams.">
 
<!-- /products page -->
<meta name="description" content="Explore Acme's suite of project tools: time tracking, Kanban boards, and automated reporting.">
 
<!-- /contact page -->
<meta name="description" content="Get in touch with the Acme Corp sales and support team — we respond within one business day.">

✅ Dynamic generation in Next.js

// app/products/page.tsx
export const metadata = {
  description: 'Explore Acme\'s suite of project tools: time tracking, Kanban boards, and automated reporting.',
}

Why It Matters

• Snippet quality: Google uses the meta description as the search snippet when it considers it relevant. Unique descriptions mean more useful snippets, and MDN's description-meta reference (opens in new tab) is a good baseline for validating the rendered tag.
• Click-through rate: A description tailored to the page's content matches user intent and earns more clicks.
• Crawl signals: Identical descriptions across pages suggest thin or duplicate content, which can suppress rankings and usually needs the same per-route treatment as meta-title generation.

What to Check

Crawl the site and collect all <meta name="description" content="..."> values. Group by content value; any group with more than one URL is a violation.

Also flag descriptions that:

• Are identical to the homepage description
• Match the site tagline verbatim
• Are left as a CMS template placeholder

How to Fix Duplicates

1. Run a site crawl with Screaming Frog (opens in new tab), Sitebulb, or Google Search Console's Page Indexing report to identify duplicates.
2. Export the list of affected URLs and their shared descriptions.
3. Write a unique, page-specific description for each URL (50–160 characters).
4. Update your CMS, template, or code to inject these per-page values.
5. Re-crawl after deploying to confirm all duplicates are resolved.

Exceptions

• Utility or intentionally noindex pages may keep minimal metadata when richer search presentation is not a goal.
• Template-driven pages can look repetitive in isolation; confirm the fully rendered production output before flagging duplication or omission.
• If a page is intentionally redirected or excluded from indexation, resolve that crawlability decision before treating metadata polish as the primary issue.

Standards

• Use these references as the standard for the final search-facing HTML, metadata, and crawl behavior.
• Check the implementation against Google Search Central: Snippet best practices before treating the rule as satisfied.
• Check the implementation against MDN: meta element name attribute — description before treating the rule as satisfied.

Verification

Automated Checks

• Inspect rendered HTML and HTTP headers to confirm the expected metadata or crawlability signal is present.
• Test the affected URL with Google Search Console or equivalent tooling where relevant.
• Re-crawl a representative page set after deployment.

Manual Checks

• Confirm the change does not create conflicting canonical-url, robots, or structured-data signals.
