A clean two-creative test for beginners

A clean two-creative test for beginners
Today: comparing ads fairly, like a science class.
A creative is your ad: the small image plus the headline. To learn which works, change only one thing at a time.
Here's the method:
— 1. Make creative A with your best image and headline.
— 2. Make creative B identical, but swap only the image.
— 3. Run both in the same campaign, same budget, same geo.
— 4. Wait until each has at least 1000 views before judging.
— 5. Keep the winner, then test a new headline against it.
Changing two things at once hides which one helped. One variable, always.
Try this: write your headline, then write a second version that says the same thing more simply. That's your first honest test.
