You think it needs a way for people to get more information about HOW to be a diver?
YUP - a very specific "call to action" is critical here!
The viewer sees the ad, and says to himself "OK, I think I'll be a diver!"
What does DEMA want that person to do NEXT?
- call an 800#?
- go to a website?
- visit a local dive center?
- book a vacation?
- look under diving in the yellow pages?
- wander beaches looking for people with tanks?
Web is the most obvious choice. In fact DEMA's marketing plan lists "drive potential customers to BEADIVER.COM to close the sale" as a key objective of the plan, so I sure hope they didn't actually forget to put the website on the ad!
