How to Use the URL Slug Generator

Toggle Remove stop words to strip filler words like “the”, “and”, and “for”, or set a Max length to truncate the output at a specific character count. Click Show transformation steps to see exactly what was changed at each stage.
What Is a URL Slug?
A URL slug is the human-readable part of a web address that identifies a specific page. In the URL https://example.com/blog/how-to-do-keyword-research, the slug is how-to-do-keyword-research. Slugs appear in browser address bars, link previews, and search results — making them both a search engine signal and a user experience element.
Unlike dynamic URLs full of query parameters (/page?id=1234&cat=5), descriptive slugs communicate the page topic at a glance. Search engines read words separated by hyphens as individual keywords, so a slug like seo-tools-for-beginnershelps you rank for “seo tools,” “tools for beginners,” and related phrases.
What the Tool Does Automatically
Lowercase conversion
All letters are lowercased to prevent case-sensitive server mismatches, which can create duplicate URLs.
Accent normalization
Accented characters like é, ü, ñ, and ø are converted to their plain ASCII equivalents (e, u, n, o) for maximum URL compatibility.
Special character removal
Characters like &, #, %, (, ) and punctuation are stripped. Only letters, numbers, and hyphens remain.
Space → hyphen
Spaces and underscores are replaced with hyphens. Google treats hyphens as word separators, so 'seo tools' becomes 'seo-tools' (two searchable words).
Consecutive hyphen cleanup
Multiple sequential hyphens are collapsed into one — so '---' becomes '-'. Prevents ugly URLs like 'my---page-title'.
Trim leading/trailing hyphens
Hyphens at the very start or end of the slug are removed, ensuring clean URL boundaries.
The Stop Words Option
Common words like “the,” “and,” “or,” and “for” add length to a slug without adding keyword value. Enabling the Remove stop words toggle strips these from the output, producing a shorter, more keyword-dense slug.
For example: The Best SEO Tools for Beginners becomes best-seo-tools-beginners instead of the-best-seo-tools-for-beginners. Both are valid, but the shorter version is cleaner and slightly more keyword-focused. Use your judgment — sometimes stop words help readability and should be kept.
Words filtered when this option is enabled: a, an, the, and, or, but, in, on, at, to, for, of, with, is, are, was, were.
Max Length and Truncation
Google recommends keeping URLs short. Setting a max length of 60 characters ensures your slug stays concise. When truncating, the tool avoids cutting words mid-way — it trims back to the nearest hyphen, so you never end up with a partial word at the end of the slug.
SEO Best Practices for URL Slugs
| Best Practice | Example |
|---|---|
| Keep it short and descriptive | /seo-tools vs /the-best-seo-tools-you-can-find |
| Use hyphens, not underscores | /keyword-research vs /keyword_research |
| Include primary keyword early | /keyword-research-guide vs /guide-to-keyword-research |
| All lowercase | /seo-tools vs /SEO-Tools |
| Remove special characters | /beginners-guide vs /beginner%27s-guide |
| Avoid dates unless necessary | /seo-guide vs /seo-guide-2024 |
Changing Existing Slugs — What You Need to Know
If you are cleaning up slugs on an existing live site, always set up a 301 redirect from the old URL to the new one. A 301 tells search engines that the page has permanently moved, transferring the accumulated ranking signals (PageRank, backlinks, etc.) to the new address. Without the redirect, you will effectively start from scratch with the new URL while the old one becomes a dead link. Use your CMS redirect settings or a server-level redirect rule, and allow several weeks for Google to fully process the change.
Frequently Asked Questions
What is a URL slug and why does it matter for SEO?
A URL slug is the part of a web address that comes after the domain name — for example, in https://example.com/seo-tools, the slug is 'seo-tools'. It matters for SEO because Google uses the URL as a relevance signal. A slug that clearly describes the page content helps Google understand what the page is about and can improve rankings. It also increases click-through rates in search results because users can see what to expect before clicking.
How long should a URL slug be?
Keep slugs concise — ideally under 60 characters and 3-5 words. Shorter URLs are easier to read, share, and type. Google recommends avoiding excessively long URLs and states that words beyond the fifth word in a URL carry less SEO weight. Remove filler words like 'how', 'to', 'the', 'a', 'and' to keep the slug focused on the core keywords.
Should I include my target keyword in the URL?
Yes. Including your primary keyword in the URL slug is a confirmed Google ranking factor, albeit a minor one. More importantly, the keyword in the URL helps users and search engines understand the page topic at a glance. Place the most important keyword at the start of the slug rather than the end whenever possible, and avoid keyword stuffing — one or two keywords per slug is the ideal.
What characters are not allowed in a URL slug?
URL slugs should only contain lowercase letters (a-z), numbers (0-9), and hyphens (-). Avoid spaces (use hyphens instead), underscores (Google treats them as word joiners, not separators — so 'keyword_research' is read as one word 'keywordresearch'), special characters like & # % ? = +, uppercase letters (which can cause duplicate content issues on case-sensitive servers), and accented characters like é, ü, or ñ (encode them or use the plain ASCII equivalent).
Hyphens vs underscores — which should I use in URLs?
Always use hyphens, not underscores. Google's John Mueller confirmed that Google treats hyphens as word separators in URLs — so 'keyword-research' is read as the two words 'keyword' and 'research'. Underscores, on the other hand, join words — so 'keyword_research' is read as the single word 'keywordresearch'. This distinction can meaningfully affect whether you rank for individual keyword terms.
