Best Practices for URL Slugs
Use Hyphens Between Words
Hyphens make slugs easier to read. Use seo-friendly-urls instead of seofriendlyurls.
Keep URLs Short
A shorter slug is easier to read and share. Try to remove words that do not add meaning.
Use the Main Keyword Naturally
If your page is about URL slugs, a slug like url-slug-guide is clear and relevant. Do not repeat keywords unnaturally.
Avoid Dates Unless They Are Needed
Dates can make content look old later. Use dates only when the page is specifically about a date, event, report, or yearly update.
Do Not Change Published URLs Without a Redirect
If a page is already published and indexed, changing the slug can break old links. If you must change it, use a proper redirect from the old URL to the new one.
Common URL Slug Mistakes to Avoid
- Using very long slugs.
- Adding random numbers or symbols.
- Using underscores instead of hyphens.
- Repeating the same keyword too many times.
- Leaving auto-generated slugs unchanged.
- Changing live URLs without redirects.
- Using vague slugs like post-123 or new-page.
