Frequently Asked Questions
What is a URL slug?
A URL slug is the part of a URL that comes after the domain name and identifies a specific page in readable keywords. For example, in example.com/url-slug-best-practices
, the slug is "url-slug-best-practices".
Should I use hyphens or underscores in URL slugs?
Always use hyphens between words in URL slugs, not underscores. Google treats hyphens as word separators but sees underscores as word connectors, making hyphens better for SEO.
How long should URL slugs be?
Keep URL slugs between 3-5 words and under 60 characters total. Shorter slugs are easier to remember, share, and rank better in search engines.
Should I include dates in URL slugs?
Avoid including dates in URL slugs unless absolutely necessary. Dates make content appear outdated and can hurt click-through rates. Use evergreen URLs like /social-media-strategy
instead of /2025-social-media-strategy
.
Can I change URL slugs after publishing?
Yes, but always use 301 redirects from the old URL to the new one, update internal links, and monitor for 404 errors. Expect temporary ranking fluctuations during the transition.
Should URL slugs match the page title exactly?
No, URL slugs should be related to the title but shorter and more concise. For example, a title like "Complete Guide to Instagram Marketing for Small Business" could have the slug /instagram-marketing-small-business
.
What words should I remove from URL slugs?
Remove stop words like "a", "the", "and", "of", "to", "how", "for" from URL slugs to keep them concise. Focus on meaningful keywords that describe the content.
Do URL slugs affect SEO rankings?
Yes, URL slugs are a ranking factor for Google. Well-optimized slugs with relevant keywords can improve search rankings and increase click-through rates from search results.
Should I use uppercase or lowercase in URL slugs?
Always use lowercase letters only in URL slugs. Mixed case can create confusion and potential duplicate content issues since URLs are case-sensitive on some servers.
Can I use numbers in URL slugs?
Use numbers in URL slugs only if they add value, like /7-instagram-tips
. Avoid arbitrary numbers like /tips-2024-v2
that don't help users understand the content.
