A URL slug is the part of a web address that identifies a specific page in a human‑readable format (e.g., /blog/seo-tips-for-beginners). Slugs help search engines understand your content and improve click‑through rates when users see clean, descriptive URLs in search results. A well‑crafted slug is concise, keyword‑rich, and easy to read.

Always use hyphens (-). Google's algorithm treats hyphens as word separators, so seo-tips is read as "SEO tips." Underscores are treated as joiners, meaning seo_tips is interpreted as a single word "seotips." This is a well‑documented SEO best practice confirmed by Google.

The sweet spot is between 3 and 5 words, or roughly 50–60 characters. Shorter slugs are easier to read, share, and remember. Google typically displays up to 60–70 characters in search result URLs before truncation. Avoid slugs over 80 characters — they look spammy and dilute keyword relevance.

Stop words are common function words like the, a, an, is, are, and, or, but, in, on, to, for, of. Removing them from your slug creates a tighter, more keyword‑focused URL. For example, /the-best-tips-for-seo becomes /best-tips-seo — shorter and more impactful without losing meaning. Our tool can automatically strip them for you.

Numbers are fine and often useful (e.g., /top-10-tips). However, special characters like ! @ # $ % ^ & * ( ) should be avoided — they can break URLs or get encoded into messy strings. Stick to lowercase letters, numbers, and hyphens. Our generator automatically strips unsafe characters and converts everything to a clean, URL‑safe format.

Non‑ASCII characters (including Chinese, Japanese, Korean, Arabic, Cyrillic, and emoji) are automatically removed from the generated slug. This ensures maximum compatibility across all browsers, servers, and search engines. If your content is primarily in a non‑Latin script, consider manually creating a transliterated slug or using a separate transliteration tool before generating.

A clean slug improves click‑through rate (CTR), helps search engines better understand page content, and makes URLs shareable on social media. Keywords in the slug are a lightweight ranking factor. Plus, when other sites link to you, they often use the URL as anchor text — a keyword‑rich slug gives you free optimized backlinks.

It depends on your content strategy. Including a year (e.g., /best-seo-tools-2024) can signal freshness to users, but it dates your content and requires updating the URL when you refresh the article. For evergreen content, omit the date. For news or time‑sensitive pieces, including the year can help with CTR in search results.
