Which of the following symbols should you use to separate the words in the slug, according to best practice?

According to best practices for SEO and URL structure, hyphens (-) should be used to separate words in a slug. This makes URLs more readable for both users and search engines. Search engines, like Google, interpret hyphens as word separators, which helps them understand the content of the page. Colons (:) and plusses (+) are not standard separators and can sometimes cause issues with URL parsing or be interpreted differently by search engines. Dots (.) are typically used to separate file extensions or subdomains, not words within a slug.
