SEO & Digital Marketing
Convert headline-case blog titles to lowercase URL slugs (kebab-case) for publishing, ensuring your URLs are clean, readable, and SEO-friendly without manually replacing every space and capital letter.
Tips & Best Practices
- Title Case capitalizes the first letter of most words but keeps short prepositions and conjunctions (like 'and', 'of', 'in') lowercase — use it for blog post headlines and page titles.
- Use kebab-case (words-joined-with-hyphens) for creating URL slugs — it is the most SEO-friendly URL format because Google treats hyphens as word separators.
- camelCase is the JavaScript convention (firstName, getUserById), while snake_case is the Python and SQL convention (first_name, get_user_by_id). Know which format your codebase requires.
- Sentence case only capitalizes the first letter of the first word and proper nouns — it is the most natural-reading format for meta descriptions and product descriptions.
