I was in the library the other day and saw a sign that said:
Free Computer Classes for Beginners
Sign up at library desk
I thought, it’s an instant marketing offer. There’s often a lot of confusion about what an offer actually is.
They don’t have to be complicated though. A few lines will do the trick.
The price: free
What it is: computer classes
The intended audience: beginners
When: the date of the class
Call to action: sign up at the desk
That’s all you really need. The rest is commentary. Now go and test.
