A digital marketer creates ad variation tests for a new headline. They intend to test an additional change to the call to action, however, they decide to make the latest variation a permanent ad change.

What should the marketer consider before creating several ad variations?

A$/$B tests do not consider demographics because it tests unknown audiences

Be strategic and selective about the ads to test because A$/$B tests take time and budget

$\frac{A}{B}$ tests require multiple perspectives for analyzing the data
