Understanding URL Slugs & Technical SEO Architecture
A URL slug is the human-readable trailing segment of a permalink that identifies a specific web page. Search engines prioritize clear, keyword-targeted slugs over cryptic parameter strings (e.g. /posts?id=83921) because they provide search crawlers and users with immediate context regarding the resource content.
Unicode Diacritic Normalization (NFD)
International headlines containing accented characters (such as crème brûlée or München) can trigger messy percent-encoding strings (like cr%C3%A8me-br%C3%BBl%C3%A9e) if not properly transliterated. SEO Slugify Studio applies Unicode Canonical Decomposition (NFD) and strips diacritical marks locally in browser RAM to produce clean ASCII-compliant slugs.

Frequently Asked Questions
Should I use hyphens or underscores in URL slugs?
Google explicitly recommends using hyphens (-) rather than underscores (_), as Googlebot interprets hyphens as word separators while treating underscores as joined characters.
Why filter stop words from slugs?
Removing short filler words (like a, the, in, to, and) shortens the permalink, keeping high-value primary keywords closer to the root domain for improved search scannability.
