A slug in WordPress is a specific piece of text that appears in a URL. In WordPress, the slug is the part of the URL that corresponds to a post or page. For example, if you have a post with the title “My First Post,” the slug would be “yourwebsite.com/my-first-post.”
They were developed to improve SEO and make website URLs more human friendly. Before slugs, URLs were just strings of letters and numbers that didn’t really correspond to the content.
With slugs, both humans and search engines have an instantly improved way to gauge what the page is about.
Slugs are typically generated automatically from the title of a post or page, but you can also specify them manually. Slugs are important for two main reasons: they help improve the usability of your website, and they can also help improve your SEO.
First, slugs make it easier for users to find specific content on your site. For example, if someone is looking for your post on “My First Post,” they can simply go to www.example.com/my-first-post/ and they’ll be taken directly to that post. This is much easier than having to remember or search for the post title.
Second, slugs can help improve your SEO. That’s because search engines use the words in the URL to help determine what a page is about. So, if you have a post with the title “My First Post” and the slug “my-first-post,” that will tell search engines that the page is about “My First Post.” This can help your page rank higher in search results for that term.
Overall, slugs are a helpful way to make your website more usable and searchable.
