Headings and subheadings are used to tell a person what they can expect from the content of a section.
No full stops at the end of any headings but fine to use a full stop or comma to break up a headline.
For example:
OUR DREAM RATE JUST GOT DREAMIER
LIFE IS EVENTFUL. THAT’S WHY WE HELP
MEET RED, YOUR VIRTUAL ASSISTANT
Question marks and exclamation marks can help keep headings short and engaging.
For example:
WANT $3K CASHBACK?
LIFE IS EVENTFUL. THAT’S WHY WE HELP
Note: Only use exclamation marks when appropriate, e.g. Now that’s a great rate!
