How to Create SEO-Friendly URL Slugs

A good URL slug is short, readable, and a clear description of the page. Use lowercase words joined by hyphens, choose a consistent approach to accented or non-Latin text, and remove words only when the result still makes sense. Once a URL is live, keep it stable; if you must change it, redirect the old address to the closest matching new one.

What is a URL slug?

A slug is the descriptive part of a web address, usually the text after the domain and any category path. In example.com/blog/choose-a-houseplant, the slug is choose-a-houseplant. The site may also use the surrounding path to organize content.

A useful slug helps people understand a link before opening it and makes the page address easier to share. It is one part of a page’s URL, not a substitute for useful content or other SEO work. A particular slug format cannot guarantee a search ranking.

Use lowercase letters and hyphens

Lowercase text gives URLs a consistent appearance and helps avoid creating separate-looking versions of the same address. Some servers treat uppercase and lowercase paths as different URLs, so a site should choose a convention and apply it consistently.

Use hyphens between words, as in how-to-choose-a-houseplant. Hyphens make word boundaries clear to readers and search systems. Avoid spaces, which browsers encode in URLs, and avoid using underscores or punctuation as separators. Remove punctuation that does not help identify the page.

To draft a slug from a title, the TIG Slug Generator can turn text into a URL-friendly form. Review the result before publishing: an automatic conversion may not preserve the meaning or terminology you want.

Choose how to handle accents and other scripts

For text using Latin letters, a common approach is to replace accented characters with their closest unaccented equivalents. For example, crème brûlée could become creme-brulee. This is called transliteration: it represents text using a different writing system or a simplified character set. It is not the same as translating the words.

For other languages and scripts, select a consistent policy that suits your site and audience. You might keep Unicode characters in URLs, or transliterate them into Latin letters. Browsers can display international characters, though URLs may be percent-encoded when represented or transmitted. The TIG Slug Generator removes accents from Latin letters (including Turkish ğ, ş and ç) but does not transliterate Cyrillic, Greek, Arabic, Chinese or other non-Latin scripts: by default it drops them, or keeps them if you turn on “Keep non-Latin letters”. If you need to inspect or encode a URL component, the URL Encoder / Decoder can help; encoding does not decide what the slug should say.

Keep names, place names, and language-specific terms recognizable. Do not apply a transliteration that changes the meaning or makes a term difficult for the intended audience to identify. For a multilingual site, create a suitable slug for each language rather than transliterating every page into one language by default.

Remove stop words selectively

Stop words are common words such as “a,” “the,” “and,” or “of.” They can often be removed to make a slug more concise, but there is no rule that says every stop word must go.

Compare these examples:

• Title: “A Guide to Choosing a Houseplant”
• Concise slug: choosing-a-houseplant
• Also clear: guide-to-choosing-a-houseplant

The shorter option works because the key meaning remains clear. In another title, removing a small word could make a phrase confusing or change its meaning. Read the slug as a person would, and keep words that help it make sense.

Avoid turning the slug into a list of repeated keywords. Use the words that describe the page naturally, not every related search phrase.

Keep slugs descriptive, not unnecessarily long

There is no universal maximum slug length that makes a URL SEO-friendly. Aim for a compact phrase that identifies the page without removing useful context. A slug based on the full title may be too long if the title includes a subtitle, date, or extra wording that is not needed to distinguish the page.

For example, a page titled “How to Choose the Right Houseplant for a Small, North-Facing Apartment” might use houseplants-for-a-north-facing-apartment. The slug retains the central topic and useful detail without repeating every word in the title.

Before publishing, check that the slug:

• Describes the page accurately.
• Is easy to read aloud and recognize in a link.
• Uses only words that help identify the page.
• Does not include unnecessary tracking data, punctuation, or repeated terms.

Do not shorten a slug so much that it becomes vague. If several pages cover similar topics, include a distinguishing word rather than using the same generic slug for all of them.

Keep published slugs stable

Choose a slug when you create the page, then avoid changing it just to match a revised headline or a new keyword idea. A URL can be bookmarked, shared, indexed, or linked from another site. Changing it without handling the old address can leave visitors with a broken link and make the page harder to find through existing links.

If the page title changes but the existing URL is still accurate, leave the slug as it is. A title and a slug do not need to match word for word. Review the URL when you make a substantial change to the page’s subject or organization, not as routine copy editing.

For a new site, decide on conventions before publishing many pages: lowercase or case handling, hyphen use, transliteration, and whether dates or category names belong in paths. Consistency makes future content easier to manage.

Change a slug with a redirect

If a URL must change, set up a permanent server-side redirect from the old URL to the new URL. A 301 redirect is commonly used for a permanent move; other permanent redirect status codes also exist. The important point is that the old address should lead directly to the page’s new address.

For example, if a guide moves from /blog/houseplant-tips to /blog/choose-a-houseplant, redirect the first path to the second. Then:

1. Update internal links so they point directly to the new URL.
2. Update the page’s canonical URL, if your site uses one.
3. Update XML sitemaps and other site references to use the new address.
4. Test the old URL and confirm it reaches the intended page without a redirect loop or unnecessary chain.

Redirect each changed URL to its closest equivalent. Do not send unrelated old URLs to the homepage just to avoid errors; that can confuse visitors. Keep redirects in place while people or external sites may still use the old address. If a page is removed and has no relevant replacement, handle that separately rather than redirecting to an unrelated page.

Worked example

Suppose you publish an article titled “The Best Way to Prepare Crème Brûlée at Home.” A clear first draft could be prepare-creme-brulee-at-home. It uses lowercase letters, hyphens, a readable transliteration, and the main topic without copying every title word.

If the article later becomes a broader guide to making the dessert, you might consider changing the slug to how-to-make-creme-brulee. First ask whether the existing URL is now misleading. If it still describes the page well, keep it. If you do change it, redirect the original URL to the new one and update your site’s internal references.

Summary

• Use lowercase text and hyphens to make slugs consistent and readable.
• Transliterate only when it suits the language and audience; keep names recognizable.
• Remove stop words selectively and choose a concise, descriptive phrase rather than a fixed length.
• Keep published URLs stable; when a change is necessary, redirect the old URL to the closest equivalent and update site references.
