A URL, Uniform Resource Locator, is the full address that specifies exactly how to reach a resource on the internet: the protocol, the domain, and the specific path to the exact page or file. https://zeo.org/blog/seo-guide is a complete URL; each part of it (protocol, domain, subfolder, page) plays a distinct role in how the request actually resolves.
A well-built URL is short, readable, and descriptive of what the page actually covers, ideally something a person could reasonably guess the content of just from reading the address itself. Including the target keyword helps, but readability matters more than cramming in every relevant term; /blog/complete-guide-to-technical-seo-audits-2026 reads clearly and still carries the keyword, while a URL stuffed with every variation of a phrase reads as spam to both search engines and people scanning a results page. URLs are also worth treating as close to permanent once published: changing one later requires a redirect to avoid losing whatever ranking signal and backlinks the original address accumulated, which is why getting the structure right from the start matters more than it might seem for a detail that's otherwise invisible to most visitors.
