Duplicate Description

Business
duplicate-description

Duplicate Description is an Agent Skill for business published in the thedaviddias/Front-End-Checklist repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Use when auditing a site's meta tag uniqueness, generating page-specific meta descriptions, or reviewing CMS templates that inject the same description globally.

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

  1. Open your project in Codex.
  2. Copy and paste the prompt below.
  3. Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/thedaviddias/Front-End-Checklist/blob/HEAD/skills/duplicate-description/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/duplicate-description, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

Avoid duplicate meta descriptions

When multiple pages share the same meta description, Google ignores them and generates its own snippet, often pulling unrelated text. Unique descriptions improve click-through rates from search results and help users quickly understand what a page offers.

Quick Reference

  • Each page must have a unique <meta name="description"> — never reuse the same text across multiple pages
  • Google may auto-generate snippets when descriptions are duplicated or missing, often producing worse results
  • Target 50–160 characters; craft descriptions that describe the specific page, not the site

Check

Scan the HTML of every page for <meta name="description" content="...">. Identify any description value that appears on more than one URL. Flag pages using the same description as another page, and flag pages where the description matches the site tagline or homepage description.

Fix

  1. List every page with a duplicate meta description.
  2. For each page, write a unique description that summarises that page's specific content (50–160 characters).
  3. In Next.js/React, pass a dynamic description prop through your SEO component instead of a static string.
  4. In WordPress/CMS, disable site-wide description fallback in your SEO plugin (Yoast, RankMath) and set per-post descriptions. Example of a unique description per page:
  • Homepage: "Front-End Checklist helps developers build faster, more accessible, and better-ranked websites."
  • Blog post: "Learn how canonical tags prevent duplicate-content penalties and consolidate PageRank across URL variants."

Explain

Duplicate meta descriptions tell Google the pages are interchangeable, diluting search visibility. Each page competes in search for different queries, so the description must match the page's unique intent and content to earn a relevant snippet and a higher click-through rate.

Code Review

Check that no two <meta name="description"> tags in the rendered HTML across different routes share identical content values. Confirm the description is set dynamically per route in the framework's head management (e.g., Next.js metadata export, Nuxt useHead).
