A slug is a unique part of a URL that identifies a particular page of a website in an easy-to-read way. It is the last section of the URL that is set by page, publication or taxonomy. If you want to attract more visitors to your WordPress website, optimizing clean URL slugs can be the first step in achieving this. WordPress website URLs often include descriptive information that allows the visitor or search engine to find out what the page is about, called a URL slug.
When you create a new category or tag from within the WordPress Editor, WordPress automatically assigns that element a slug without any intervention on your part. To optimize your slugs for SEO, you need to set up WordPress to use the name of the publication as a slug instead of serial numbers. This will make it easier for search engines to understand what your page is about and rank it higher in search results. The Yoast SEO plugin checks if the slug contains the key phrase of your focus, which is also important for SEO.
By optimizing your WordPress slugs for SEO, you can improve your website's visibility and attract more visitors. This will help you get more traffic and increase your chances of success.
