Slugify Your Page Title Slugs make the URL more user-friendly and visitors know what to expect when they click on a link. Slugs should be short and concise and contain the words that help with your target keywords. A slug is a part of a URL, which usually describes the article. It is the section that comes after your domain name in the URL. It’s a combination of words or a simple phrase that defines the actual meaning of a link with all the unnecessary words and symbols removed.
