WordPress is probably the most popular webpage markup creation tool on the internet. That being so, many people have questions about slugs.
What is a slug?
Let's say, for example, my website was a personal blog with the domain name stlplaces.com
Now let's say I am writing a post "Best Software Quality Assurance & QA Books" called
/best-software-quality-assurance-and-qa-books would be the slug and the entire URL for the review might then become, stlplaces.com/blog/best-software-quality-assurance-and-qa-books.
Why use a slug?
Because using a slug helps both customers and search engines such as Google more easily identify the content you are laying out for people.
Using a slug makes it much more certain that your content will be found, as the slug tells people in short, exactly what to expect.
You can easily edit your slugs, and they can become vital to attracting an audience for your content.
