Google Official SEO Slug Recommendation: Hyphens over Underscores
Google Search Central officially recommends using hyphens (kebab-case) rather than underscores (snake_case) in website URLs. Google treats hyphens as standard word separators (e.g., website-speed is indexed as two distinct words: "website" and "speed"), whereas underscores can concatenate terms in certain search parsers.
Frequently Asked Questions
How does Sentence Case handle multiple sentences?
Our engine uses regular expression boundary detection to automatically capitalize the initial letter of every sentence following periods (.), question marks (?), and exclamation marks (!).
Is any text uploaded to a server during conversion?
No. The entire conversion process runs locally in your browser memory via native JavaScript string manipulation. Zero text data ever leaves your device.
