SEO Friendly URL

A short, readable web address that clearly describes the page topic, helping users and search engines understand the content before clicking.

If you have ever used underscores in a URL, stuffed multiple keywords into the slug, or ignored case sensitivity, you already know the difference between a readable link and a technical mess.

Key points

  • Use hyphens, not underscores, to separate words in URL slugs.
  • Keep URLs lowercase to avoid accidental duplicate content from case-sensitive servers.
  • Remove unnecessary words and parameters, but preserve readability for users.
  • Set up a 301 redirect whenever you change a URL to preserve link equity and indexing.
  • Avoid keyword stuffing in the slug; one clear topic word is enough.

From cryptic to clear: a furniture site rewrite

A product page for a wooden garden chair originally sat at www.example.com/products?id=1234&cat=5. The owner changed the URL to /wooden-garden-chair and set a 301 redirect from the old address. Within six weeks, the page’s organic click-through rate rose by 18% and it began ranking for the exact phrase “wooden garden chair” — a term it had never appeared for before.

Three ways it goes wrong

  • Keyword stuffing Packing the slug with every related term (e.g., /buy-red-running-shoes-online) makes URLs look spammy and reduces trust. Keep it to one or two natural words.
  • Cryptic IDs Using database IDs or session parameters (e.g., /product.php?id=456) obscures the page topic for both users and search engines. Replace with descriptive words.
  • Mixed case A URL like /Product-Name can cause duplicate content if the server treats /product-name as a different page. Always use lowercase.

Three things to check before launching

  • Hyphen vs underscore Google treats hyphens as word separators but underscores as word joiners, which can cause readability and parsing issues. Use hyphens in your slugs and run an SEO-friendly test to confirm the structure works as expected.
  • Parameter clean-up Google recommends removing unnecessary parameters that do not change the content. Use URL parameters only when essential (e.g., for sorting or pagination).
  • Canonical tag Set a canonical URL on pages with similar or duplicate content to consolidate ranking signals and avoid duplicate content issues. This tells search engines which version is the master.
