URL Length and Slug Optimization: The Complete 2026 Guide

Google displays a maximum of 60-70 characters of a URL in search results. Anything beyond that gets truncated with an ellipsis. A 2025 study by Ahrefs found that the average URL of top-ranking pages is around 40-50 characters. Pages with URLs under 60 characters consistently perform better in organic search. https://ahrefs.com/blog/seo-friendly-url/

Long URLs get copied wrong. They break in email links. They look spammy in SERP snippets. Users trust short, clean addresses. Moz reported that shorter URLs tend to attract more clicks because users can scan them quickly. https://moz.com/learn/seo/url

A slug is the last part of the URL: yoursite.com/blog/this-is-the-slug. Keep slugs between 3-5 words. The ideal total URL length is under 60 characters. Each folder in the path counts toward the total. Remove stop words like "the", "and", "of", "a", and "for" from slugs. These words add length without meaning.

Example of a bad slug: /blog/the-best-and-most-effective-ways-to-improve-your-sites-search-engine-optimization-strategies/

Example of a good slug: /blog/seo-strategy-improvement-tips/

Use the primary keyword first. Google places more weight on the first words in a URL. Put the main keyword at the beginning of the slug.

Remove dates from slugs. A 2025 recommendation from Google's developer docs suggests keeping dates out of URLs unless the content is time-sensitive news. Dated URLs look stale over time. https://developers.google.com/search/docs/appearance/structured-data/article

Use exact match keywords where natural. If the page title is "How to Fix Broken Links", the slug should be /fix-broken-links/. Exact match slugs reinforce topic relevance. Do not force keywords into unnatural phrasing.

Avoid ID-based slugs. Slugs like /post?id=38291 or /post/38291 provide no context. Every slug should describe the page content. ID-based slugs waste a valuable ranking opportunity.

Use hyphens, not underscores. Google's Matt Cutts confirmed that hyphens are treated as word separators and underscores are not. A hyphen is ASCII character 45. An underscore is ASCII character 95. Google's algorithm treats them differently. https://developers.google.com/search/blog/2005/12/urls-best-practices-for-crawlable

Keep slugs in lowercase. Apache and Nginx servers are case-sensitive by default. /Blog/Seo-Tips and /blog/seo-tips can point to different files on some configurations. Lowercase slugs eliminate this risk.

Avoid special characters. Characters like apostrophes, commas, brackets, and accented letters cause encoding problems. Stick to letters, numbers, and hyphens.

• Slug is under 50 characters
• No stop words present
• Primary keyword starts the slug
• Lowercase only
• Hyphens only as separators
• No numbers or dates unless necessary
• No special characters

Crawl your site and extract all URL paths. Flag any slug longer than 5 words. Flag any URL over 70 characters total. Check for underscores, mixed case, or ID-based patterns. Note the gap between current slugs and the recommendations above. Audit quarterly.
