Turn any title into a clean, SEO-friendly URL slug, lowercase, hyphenated, accent-free, and trimmed to a safe length.
This takes any title or heading and normalizes it into a clean URL slug: it strips accented characters down to their plain Latin equivalents, removes punctuation, lowercases everything, joins words with your chosen separator, and optionally trims common stopwords and enforces a length cap. Everything happens as you type, with a live character count and an optional full-URL preview.
Hyphens. Google has said for years that it treats a hyphen as a word separator but an underscore as a literal character that glues words together, which can hurt how individual words in your URL are indexed. Hyphens are the standard for SEO-friendly slugs.
It's optional and mostly a style choice. Dropping short filler words can make a slug shorter and cleaner, but for some titles it can also make the URL read strangely or lose a bit of meaning, there's no ranking penalty either way, so pick whichever reads better to you.
No, it's a practical guideline, not a technical requirement. Google can index much longer URLs, but shorter, descriptive slugs tend to display better in search results and are easier for people to read, share, and remember.
