Over the weekend, I was writing a new ad for my thriller series. The goal is to get people to join my mailing list by offering them a free novel and short story.

I advertise my novels heavily on Facebook, which provides a preview of the ad as you create it.

There are three views: desktop, smartphone and feature-phone, with desktop being the default.

I wrote what I thought was a pretty good ad. It combined elements that had worked well for me in previous campaigns.

Then it came to preview time.

The desktop version looked great. Here it is.
