SEO & Copywriting Optimization Tips
- SEO Friendly URLs: Always use lowercase hyphenated slugs (kebab-case) for web links. Google treats hyphens as word separators.
- Consistent Title Headlines: Title Case elevates the visual appeal of blog articles, boosting click-through rates in social shares.
- Email Formatting: Ensure email subject lines use Sentence case or Title Case to prevent spam filters from flagging all-caps text.
