Here's what you need to know about writing good headlines, form the Constant Contact blog, at Headline Writing: Three Core Factors That Trigger Curiosity.
Every headline you write should answer one or more of these questions readers might have:
- Is this for me?
- Is it something I know or don't know?
- Would I get any benefit by reading this?
Answer those, and you're well on your way to involved readers who care about your superb copy. Clever, punny, self-involved headlines don't do that.
This applies not only to headlines, but also envelope teasers and email subject lines.
