Definition

An SEO-friendly URL is a web address that uses readable words, hyphen-separated terms, and a stable, predictable structure — in contrast to URLs dominated by long ID numbers, session identifiers, or unnecessary parameters.

Google's URL structure guidance asks site owners to use words rather than long ID numbers in URLs, separate words with hyphens rather than underscores, and avoid session IDs and irrelevant parameters that fragment the same content across many addresses. Readable URLs make link anchors more meaningful when other sites cite the page, and they appear directly in search results above the title link, so the address itself becomes a small signal of relevance for both crawlers and users.

Examples

• Readable slug

  A blog publishes a post at `/guides/setting-up-a-home-office` instead of `/p?id=48213&cat=12`, making the topic obvious from the URL alone.

• E-commerce structure

  A retailer uses `/womens/running-shoes/nike-pegasus-41` so the category hierarchy and product are visible in the path; tracking parameters are added separately and consolidated with a canonical tag.
