What is a URL slug, and what makes a good one?
A slug is the readable portion of a URL that identifies a specific page — just the descriptive path segment, like "seo-tools" in example.com/seo-tools, as opposed to the full web address. A good one is short, descriptive, readable and relevant to the topic, avoiding unnecessary numbers or complicated characters that make it harder to scan at a glance.
How do you actually create an SEO-friendly slug?
Start from the page's main topic, remove unnecessary words, lowercase everything, and separate words with hyphens rather than underscores, which are generally preferred for readability — that's exactly the process this tool automates from a title. Lowercase matters beyond style too: on some servers, uppercase and lowercase URLs are treated as different addresses entirely, which risks creating accidental duplicate-URL issues. A relevant descriptive phrase helps, but don't stuff a slug with keywords — removing genuinely unnecessary stop words can shorten it, but readability should always win over trimming for its own sake, and simple lowercase words with hyphens produce a cleaner result than unnecessary punctuation or special characters.
How long should a slug be, can changing one hurt SEO, and does it actually affect rankings?
There's no universal length limit, but shorter, descriptive slugs are easier to read, share and remember than long ones. Changing an established slug can hurt SEO if the old URL isn't properly redirected — use a permanent redirect and update internal links whenever you change one that's already live. As for rankings directly: a URL provides some contextual information, but changing a slug purely to insert keywords is unlikely to move rankings by itself — clarity and consistency matter more than keyword placement in the URL.
Why is it even called a 'slug' in the first place?
The term is inherited from a much older profession than web development: newspaper journalism, which borrowed it from hot-metal printing. Printers once set type from molten lead, and a single cast line of that lead type was called a slug — a term recorded in typography as early as 1871. By around 1925, newsrooms had adopted "slug" for the short internal name editors gave a story while it was still in progress, moving through drafts and galleys before it earned a real headline — named that way because the short label typically occupied the space of exactly one physical slug of type. Web developers inherited the word for exactly the same reason newspapers used it: a short, working, internal identifier for a piece of content before (or instead of) its full, polished title — which is precisely what a URL slug still is today.
