URL slug generator

What is a URL slug and why does it matter for SEO?

A URL slug is the part of a URL that comes after the domain and directory path, the human-readable identifier for a specific page. For example, in https://example.com/blog/best-domain-registrars-2026, the slug is best-domain-registrars-2026. Slugs appear in browser address bars, search engine result snippets, and social media shares, making them a significant factor in both user experience and SEO.

Google uses URL structure as a minor ranking signal and recommends using short, descriptive slugs that include the target keyword. More importantly, clean slugs improve click-through rates from search results, users and marketers scan URLs before clicking to assess relevance and trustworthiness. A slug like p?id=4821 is opaque and untrustworthy; keyword-density-checker immediately communicates the page's content.

Best practices for slug creation: use lowercase letters and hyphens (never underscores, Google treats underscores as word joiners, not separators), keep slugs under 60 characters where possible, strip stop words (the, and, of, a) to reduce length without losing meaning, and include your primary keyword. Never change a slug on a live page without setting up a 301 redirect from the old URL, or you will lose all accumulated backlink authority.
