Best Practices for Writing Headlines
Great headlines grab attention and clearly communicate value within tight character limits. Different platforms have different requirements, so it's crucial to optimize your copy for each channel.
Front-load important words: Put key information at the beginning in case it gets truncated
Use power words: Action verbs and emotional triggers increase engagement
Test multiple variations: A/B test different headline lengths and styles
Consider mobile: Email subject lines show ~30-40 chars on mobile devices
Include numbers when relevant: "5 Ways to..." often outperforms generic headlines
Avoid clickbait: Be specific and deliver on your promise to build trust
