Subheadline
01 Definition
Subheadline meaning: A secondary line under a headline that adds detail and supports the main promise.
A subheadline is the supporting line that sits directly below a headline. It expands on the main idea, adds context or proof, and bridges the reader toward the body copy. On landing pages it often clarifies the offer that the headline only hints at.

Why it matters
How Subheadline fits the work
The subheadline gives readers a second reason to keep going after the headline, letting you add detail or credibility without cluttering the main title.
In context
Below the headline 'Ship Faster', the subheadline reads 'Automate your deploys and cut release time from hours to minutes.'
Practical note
Keep the subheadline focused on one supporting idea. If it simply repeats the headline, it wastes attention; use it to answer the reader's next question.
