A slug is a string of text that appears in the URL of a web page. It is usually a short and human-readable description of the page’s content, often derived from the page title or some other relevant information. A slug is an essential component of a URL, as it helps to identify the page and provides context for search engines and users.


The purpose of a slug is to create a URL that is both human-readable and search engine-friendly. In contrast to the generic URLs that are generated by many content management systems, a slug provides a meaningful and concise description of the page’s content. By including keywords relevant to the page’s content in the slug, it can also help with search engine optimization (SEO) by making it easier for search engines to understand what the page is about.

Additionally, a well-crafted slug can also improve the user experience. A user who sees a URL with a clear and descriptive slug is more likely to understand what the page is about and be more likely to click on the link. A slug can also make it easier for users to remember the URL and share it with others.


A slug is typically created by taking the title of the page or some other relevant information and removing any unnecessary words or characters. The resulting string of text is then converted into a URL-friendly format by replacing spaces with hyphens or underscores and removing any special characters. For example, a page with the title “10 Tips for Writing Better Web Content” might have a slug of “10-tips-writing-better-web-content”.

Slugs are often used in content management systems (CMS) to automatically generate URLs for new pages or posts. Some CMS platforms allow users to customize the slug for each page or post, while others generate the slug automatically based on the page title or other relevant information.

To use a slug in a URL, it is typically added to the end of the domain name and separated by a forward slash. For example, if the domain name is “” and the slug is “10-tips-writing-better-web-content”, the full URL would be “”.

Best Practices

When creating a slug, there are several best practices to keep in mind to ensure that it is both effective for SEO and user-friendly.

Keep it Short and Simple

A slug should be short and simple, ideally no more than 5-6 words. This makes it easy for users to read and remember and reduces the risk of errors when typing the URL.

Use Keywords

Including relevant keywords in the slug can help with SEO by making it easier for search engines to understand what the page is about. However, it is important not to overdo it and stuff the slug with too many keywords, as this can be seen as spammy and harm the page’s rankings.

Use Hyphens or Underscores

To make the slug URL-friendly, it is important to use hyphens or underscores to separate words. Avoid using spaces or special characters, as these can cause problems with some browsers and servers.

Avoid Duplication

To avoid confusion and to keep the URL structure clean, it is important to avoid duplicating slugs for different pages. Each page should have a unique slug that accurately reflects its content.

Avoid Stop Words

Stop words are common words like “the”, “and”, “a”, and “is” that do not add significant meaning to the content. Avoid including these in the slug, as they can make it longer and less user-friendly.
