URL Best Practices
| Rule | Example |
|---|---|
| Use hyphens, not underscores | /web-design/ not /web_design/ |
| Lowercase only | /about-us/ not /About-Us/ |
| Short and descriptive | /tools/pdf-merge/ not /tools/id/12345/ |
| Include target keyword | /guides/svg-optimization/ |
| Avoid unnecessary parameters | /products/shoes/ not /products?cat=shoes |
URL Hierarchy
URLs should reflect your site's content hierarchy:
https://example.com/ (homepage)
https://example.com/tools/ (category)
https://example.com/tools/pdf-merge/ (tool page)
https://example.com/guides/ (category)
https://example.com/guides/pdf-tips/ (guide page)
Slug Creation Rules
- Remove stop words (a, the, is, and) unless they add meaning
- Use the primary keyword
- Keep under 5 words when possible
- Remove special characters and accents
- Make it human-readable and memorable
URL Migration
When changing URL structures:
- Create a complete redirect map (old → new)
- Implement 301 redirects for every old URL
- Update internal links to point to new URLs
- Update XML sitemap
- Monitor Search Console for crawl errors
- Keep redirects in place permanently
Common Mistakes
- Changing URLs without setting up redirects (causes 404s and lost rankings)
- Including dates in evergreen content URLs (
/2024/seo-tips/becomes stale) - Using IDs instead of slugs (
/post/12345/tells users and search engines nothing) - Redirect chains (A → B → C) that waste crawl budget and lose link equity
- Duplicate content from trailing slash inconsistency (pick one and redirect the other)
