How to Create SEO-Friendly URLs

The URL is a page's address. It appears in the browser bar, in search results and in shared links. A clear URL helps people understand the topic, inspires trust and makes the site easier to manage.

The essential rules

• Short and readable: a few words that describe the page (/seo-title-tag/) rather than a long sentence.
• Hyphens to separate words: Google recommends hyphens rather than underscores (_).
• Lowercase: addresses can be case-sensitive, and mixing upper and lower case creates duplicates.
• The main topic in the URL, naturally, without repetition.
• No special characters or spaces. For languages with accents, it is safer to remove them, since accented characters get encoded in links.
• Consistent: choose a rule (with or without trailing slash, with or without www) and apply it everywhere.

A logical hierarchy

For a structured site, the URL can reflect the organization: /blog/technical-seo/xml-sitemap/. Avoid overly deep structures, though: two or three levels are generally enough.

What to avoid

• Cryptic identifiers: /p?id=48291 tells neither visitors nor engines anything.
• Needless parameters and session IDs, which create duplicates.
• Dates in the URL for timeless content: they give an impression of dated content and complicate updating.
• Excess stop words ("the", "of", "for"): removing them shortens the address, but keep it readable.
• Very long URLs that repeat the entire title.

Examples

• Hard to read: https://www.example.com/index.php?page=12&cat=7
• Fine: https://www.example.com/blog/optimize-images-seo/

A URL is chosen once

Changing the URL of a published page has a cost: existing links and the page's history are affected. If you must do it:

• Set up a 301 redirect from the old address to the new one.
• Update internal links, the sitemap and the canonical.
• Monitor Search Console after the change.

For WordPress or other CMS sites, define the address structure at installation. A good URL is one you will never need to change.
