Slug Generator

Generating a URL slug with our tool is immediate.

1. 1

   Enter your text. Type or paste your blog post title, page name, product name, or any text you want to convert into a URL slug. The input can be of any length and can contain spaces, punctuation, special characters, and mixed case letters.

2. 2

   Choose your separator. Select either a hyphen or an underscore as the character that will replace spaces between words. Hyphens are the strongly recommended choice for all public-facing URLs and are explained in detail below.

3. 3

   Toggle the lowercase option. Most URLs should be fully lowercase to avoid duplicate URL issues and to follow web conventions. The lowercase toggle converts every letter in the output to lowercase. This option is on by default and should be left on in nearly all cases.

4. 4

   Click "Generate Slug." Your cleaned, formatted slug appears instantly in the output field. Click the copy button to grab it and paste it directly into your CMS, code, or configuration.

A URL slug is the part of a web address that comes after the domain name and identifies a specific page. It is the human-readable, simplified version of a page's title formatted to work inside a URL.

In the full URL https://www.example.com/blog/how-to-bake-sourdough-bread, the slug is the final segment: how-to-bake-sourdough-bread. It is lowercase, uses hyphens to separate words, and contains no spaces, special characters, or punctuation.

The word "slug" in this context is a publishing term borrowed from the newspaper industry, where a slug was a short label used internally to identify a story before publication. In web development and content management, the slug serves the same purpose: a short, clean identifier for a piece of content.

Slugs appear in virtually every type of web content. Blog post URLs use slugs based on the post title. Product pages use slugs based on the product name. Category and tag pages use slugs based on the category or tag name. Even user profile pages in web applications often use a slug based on the username.

URL slugs are one of the many on-page factors that influence how search engines rank and understand your content. Their impact is real and measurable, even if they are not the most heavily weighted ranking factor.

Search engines read your URL slug as a signal about what your page is about. When your slug contains the primary keyword for the page, it reinforces the relevance signal that your title tag, headings, and body content are already sending. A URL like yoursite.com/blog/best-espresso-machines tells both Google and the user exactly what the page covers before they even click.

Slugs appear in search engine results pages (SERPs) beneath the page title. A clean, descriptive slug makes your result look more credible and relevant than one with a long query string or a random string of numbers and letters. Research consistently shows that users are more likely to click on URLs that look clean and topically relevant to their search query.

Slugs are also read by link builders, journalists, and anyone considering linking to your content. A clean slug is more likely to be linked to and cited than an opaque one, which indirectly improves your domain authority over time.

Breadcrumbs and site navigation often derive their labels from slugs, which means a well-named slug contributes to a better internal linking structure and site architecture.

A well-formed URL slug follows a set of conventions that search engines and web standards have settled on over many years.

• Keep it short. The ideal slug is between three and five words. It should capture the core topic of the page without including every word from the title. A blog post titled "10 Proven Ways to Improve Your Morning Productivity Routine in 2025" might become improve-morning-productivity or morning-productivity-tips. Shorter slugs are easier to read in SERPs, easier to share, and easier to type.

• Include your primary keyword. The slug should contain the main keyword you want the page to rank for. This is one of the simplest and most consistently recommended on-page SEO actions. If your target keyword is "email marketing tips for beginners," your slug might be email-marketing-tips-beginners or beginner-email-marketing-tips.

• Use lowercase letters only. URLs are technically case-sensitive on most web servers. The path /Blog/Post and /blog/post may be treated as two different URLs, which can cause duplicate content issues. Using only lowercase letters in slugs eliminates this risk and follows universal web convention.

• Use hyphens to separate words. Google officially recommends hyphens as word separators in URLs. The search engine treats a hyphen as a space between words, which means each word in a hyphenated slug is recognized as an individual term. Underscores are treated differently and are not recommended for public-facing URLs.

• Remove stop words. Stop words are common words like "the," "a," "an," "and," "or," "but," "is," "in," "at," and "of." These words add length to a slug without adding meaning or keyword value. Removing them makes the slug shorter and more focused. "How to Write the Perfect Blog Post" becomes how-to-write-perfect-blog-post.

• Avoid special characters, punctuation, and symbols. Characters like !, @, #, $, %, &, *, (, ), [, ], {, }, and ? either break URLs or get percent-encoded into unreadable strings like %21 or %26. Thetoolity's slug generator strips these characters automatically.

• Avoid numbers unless they are meaningful. Numbers in slugs can cause problems when content is updated. A slug like top-10-seo-tools may become inaccurate if the article expands to cover 15 tools. Use numbers only when they are a permanent, meaningful part of the topic.

• Make it readable to a human. Before using any slug, read it aloud. If it makes sense as a phrase describing the page, it is a good slug. If it sounds like a random string of keywords, restructure it.

The choice between hyphens and underscores is one of the most commonly misunderstood aspects of URL slug formatting. The answer is clear: use hyphens.

Google has stated publicly and repeatedly that it treats hyphens as word separators in URLs. This means the URL my-blog-post is understood by Google as three separate words: "my," "blog," and "post." Each word is indexed individually, which allows the URL to contribute to keyword relevance.

Google does not treat underscores as word separators. The URL my_blog_post is read as a single word: "myblogpost." Unless "myblogpost" is the actual keyword you are targeting, the underscore slug contributes nothing to keyword relevance and may actively reduce your URL's effectiveness.

The preference for hyphens also extends to human readability. In most fonts and at most sizes, a hyphen between words makes a URL easier to read than an underscore, which can visually blend into the underline formatting of a hyperlink.

The only context where underscores are commonly used and accepted in URLs is within technical and developer contexts such as API endpoint names, Python variable conventions carried into URL paths, and legacy systems where underscores were the historical standard. For any public-facing SEO content URL, always choose hyphens.

Thetoolity's slug generator defaults to hyphens and recommends them for exactly these reasons.

When you paste a title into Thetoolity's slug generator and click generate, a series of text transformations happen automatically. Understanding this process helps you predict and trust the output.

• First, all letters are converted to lowercase. This ensures the slug follows standard web conventions and avoids case sensitivity problems.

• Second, any accented or special Latin characters are transliterated to their plain ASCII equivalents. For example, characters like é become e, ñ becomes n, and ü becomes u. This makes the slug universally readable and safe in all URL contexts.

• Third, all punctuation marks and special characters are removed. Apostrophes, quotation marks, periods, commas, exclamation marks, question marks, and all other non-alphanumeric characters are stripped out completely.

• Fourth, all spaces are replaced with the separator you have selected, either a hyphen or an underscore.

• Fifth, consecutive separators are collapsed into one. If removing a special character leaves two hyphens next to each other, they are merged into a single hyphen.

• Sixth, leading and trailing separators are removed. A slug should not begin or end with a hyphen or underscore.

The result is a clean, valid, URL-safe slug that can be dropped directly into any URL structure without further editing.

Every major content management system uses slugs to build page URLs. Here is how slug generation works in the most common platforms.

WordPress generates a slug automatically from your post title when you create a new post. You can see and edit the slug in the post editor beneath the title field. The auto-generated slug typically removes common stop words and replaces spaces with hyphens. If WordPress generates an undesirable slug from a complex title, Thetoolity's generator gives you a clean alternative to paste directly into the WordPress slug field.

Shopify creates slugs for product pages, collection pages, and blog posts automatically. Product slugs appear in the URL as /products/product-slug. You can edit them in the "Search engine listing preview" section of each product, collection, or blog post editor.

Webflow allows you to set a custom slug for each page, collection item, and blog post. The slug field is in the page settings or collection item settings panel. Webflow enforces lowercase and hyphen-separated slugs automatically when you save.

Ghost generates a slug from your post title when you publish. You can edit it in the post settings panel before or after publishing. Ghost is strict about slug format and will sanitize any invalid characters you try to enter.

Next.js, Nuxt, Astro, and other JavaScript frameworks use file-based routing or dynamic routes where the slug is either the filename or a URL parameter. Content-heavy sites built on these frameworks typically derive slugs from content titles stored in a CMS or markdown front matter.

Strapi, Contentful, Sanity, and other headless CMSs often include a slug field as a standard content type field that auto-populates from a title field. These can be customized at the field configuration level.

In all of these cases, having a slug ready from Thetoolity's generator before you create or publish content saves time and ensures consistency.

Knowing what not to do with URL slugs is as important as knowing best practices. Here are the most common slug mistakes and why each one matters.

• Using the full title as the slug without editing. Long, wordy titles make poor slugs. "My Top Recommendations for the Best Coffee Shops to Visit in Seattle Washington" becomes an unwieldy URL that is hard to share and harder to read in a SERP. Trim it to something like best-coffee-shops-seattle.

• Including dates in slugs unnecessarily. A slug like 2023/01/15/seo-tips ages poorly. When the article is updated in 2025, the URL still says 2023, which can undermine credibility. Avoid dates in slugs unless the content is inherently time-sensitive and you intend to publish new URLs for each time period.

• Using generic slugs. Slugs like page-1, post-23, or untitled-document carry zero keyword value and tell search engines and users nothing about the content. Every slug should be descriptive.

• Changing slugs on published pages without redirects. When you change a slug after a page is already indexed and linked to, the old URL becomes a 404 error. Any links pointing to the old URL stop passing authority to your page. If you must change a slug, always set up a 301 redirect from the old URL to the new one.

• Using uppercase letters. While most web servers handle this without errors, using uppercase creates potential for duplicate content if the server treats cases differently. Stick to all lowercase always.

• Using query strings instead of slugs. URLs like yoursite.com/index.php?p=1247 are technically functional but SEO-unfriendly, unreadable to humans, and difficult to share. Always configure your CMS or framework to use clean, slug-based URLs.

Slug generators are useful across every role that touches web content.

• Content writers and bloggers use slug generators every time they publish a new article. After writing a headline, converting it to a clean slug takes one second and ensures the URL is optimized before the post goes live.

• SEO specialists use slug generators when auditing URL structures, planning content migrations, and setting up new content briefs. A consistent slug convention across a site improves crawlability and reduces the chance of duplicate content.

• Web developers use slug generators when building routing systems, database-driven content types, and API endpoints. Programmatically generating slugs from titles is standard in most web frameworks, but a manual generator is useful for testing and one-off content creation.

• E-commerce teams use slug generators for product URLs, category pages, and collection names. A product named "Men's Premium Wool Winter Coat (Charcoal)" needs a clean slug like mens-premium-wool-winter-coat rather than mens-premium-wool-winter-coat-charcoal to keep URLs manageable.

• Marketing teams use slug generators when creating landing pages, campaign URLs, and content downloads. Clean, keyword-rich slugs for landing pages support both paid and organic traffic campaigns.

• No-code and low-code builders using platforms like Notion, Webflow, Bubble, or Framer benefit from having a reliable slug generator to ensure their automatically generated slugs are optimized before publishing.
