Keep URLs concise

SkillDev tools

Length is an agent skill for auditing and improving URL structure. It checks page paths for excessive length, deep nesting, stop words, dates, and tracking parameters, then suggests shorter slugs and flatter hierarchies. It is useful when generating slugs from article titles or reviewing URL patterns in a CMS or router configuration.

Available today. Use it from your connected AI after setup.

Have the agent skill installed and available to the agent.

Then ask your AI: use the Keep URLs concise skill

What your AI can do with it

  • Flag URL paths over 100 characters and paths with more than 4 segments
  • Detect stop words like 'the', 'a', 'of', and 'in' in slugs
  • Spot dates in URLs for evergreen content and session IDs or tracking parameters in paths
  • Suggest shortened slugs, e.g. /a-comprehensive-guide-to-css-grid-layout → /css-grid-guide
  • Recommend flattening nested structures and 301 redirects to preserve link equity
  • Report the longest 10 URLs by character count and deepest 10 by segment count

Getting started

  1. Have the agent skill installed and available to the agent.
  2. Provide the URLs, sitemap, or router/CMS configuration to review.
  3. Ask the agent to audit the paths for length, depth, stop words, dates, and tracking parameters.
  4. Review the flagged URLs and suggested slug rewrites.
  5. Apply fixes with 301 redirects and update sitemaps and internal links.

What this skill tells your AI

The instructions your AI receives, as published by thedaviddias/front-end-checklist in skills/length/SKILL.md and read by ahel’s review.

While Google has no strict URL length limit beyond technical constraints, long URLs with deep nesting, excessive parameters, or redundant words are harder for users to read, copy, and share. Google's John Mueller has confirmed that shorter, cleaner URLs are easier to understand and may perform slightly better in search.

Quick Reference

  • Keep URL paths under 100 characters; Google recommends short, descriptive URLs without unnecessary parameters
  • Remove stop words (the, a, of, in) from slugs — /guide-css-grid is better than /a-guide-to-css-grid
  • Deeply nested paths (/blog/2024/03/category/subcategory/post-title) are harder to share and signal distance from the root

Check

For each page URL, extract the path component (excluding domain and query string). Flag: (1) Path length over 100 characters. (2) More than 4 path segments (e.g., /a/b/c/d/e has 5 segments). (3) Common stop words in slugs (the, a, an, of, in, at, to, for, with). (4) Dates in URL paths for evergreen content (e.g., /blog/2024/03/css-guide). (5) Session IDs, tracking parameters, or other dynamic values in paths.

Fix

  1. Shorten slugs by removing stop words:
    • /how-to-optimise-your-websites-core-web-vitals → /optimise-core-web-vitals
    • /a-comprehensive-guide-to-css-grid-layout → /css-grid-guide
  2. Flatten URL structure where category hierarchy is not essential:
    • /blog/2024/march/technology/css-grid → /blog/css-grid
  3. Remove dates from evergreen content URLs (with 301 redirects from old URLs).
  4. Remove session IDs and tracking parameters from URLs used as canonical-url URLs.
  5. Implement changes with 301 redirects from old to new URLs to preserve link equity.
  6. Update sitemaps and internal links after URL changes.

Explain

Google recommends keeping URLs 'simple, descriptive, and readable'. Long URLs are more prone to being truncated in search snippets, harder to share, and more confusing to users. Deep URL structures (many subdirectories) do not directly harm rankings, but they can increase crawl distance from the root, reducing crawl frequency for deep pages on large sites.

Code Review

Parse the pathname of each URL. Count path segments (split by /). Measure character length of the path. Flag slugs containing common stop words. Report the longest 10 URLs by character count and deepest 10 by segment count. Check whether URL generation utilities strip stop words and limit segment depth.

Questions

Does URL length affect SEO?
Deep nesting does not directly harm rankings, but Google's John Mueller has said shorter, cleaner URLs are easier to understand and may perform slightly better. Long URLs can also be truncated in search snippets.
What counts as a problem URL?
Paths over 100 characters, more than 4 segments, stop words in slugs, dates on evergreen content, and session IDs or tracking parameters in paths.
How should URL changes be implemented?
Use 301 redirects from old to new URLs to preserve link equity, then update sitemaps and internal links.
