Frequently Asked Questions
Why are hyphens preferred over underscores for SEO URL slugs?
Search engines, including Google, treat hyphens as standard word delimiters. An underscore connects words into a single continuous token (e.g. "three_dimensional" is indexed as "threedimensional"), whereas hyphens allow algorithms to parse individual keywords.
Should I remove stop words from my URL slugs?
Removing stop words like "a", "the", "in", and "to" keeps URLs short, concise, and focused on high-intent target keywords. Short slugs are also easier to share on social media and do not get truncated on search engine result pages.
How are accented characters and non-English letters handled?
The generator applies Unicode NFD (Normalization Form Canonical Decomposition) to decouple base Latin characters from diacritical marks (e.g., separating "e" and acute accent) and strips the accents, converting "café" to "cafe" and "résumé" to "resume" for standard URL safety.
What is the optimal character length for an SEO URL slug?
The recommended sweet spot for URL slugs is between 20 and 60 characters (approximately 3 to 5 words). Slugs exceeding 60 characters are often truncated in mobile search result snippets.
Does this slug generator send any data to external servers?
No. The entire slugification engine runs locally inside your browser memory using JavaScript regular expressions and string transformers. Your draft titles and content remain strictly private.
