What is Subheadline?
A subheadline is a secondary line placed near a headline to clarify the promise, add context, define the audience, or explain a mechanism the main headline cannot fit.
What good subheadline looks like
A useful subheadline adds new information rather than restating the headline, and it should make the offer or topic easier to understand before the reader continues.
- Let the headline carry the main idea.
- Use the subheadline for audience, mechanism, evidence, scope, or qualification.
- Keep it short enough to function as supporting copy rather than a paragraph.
