Each of the following banners were tested for CTR (click-through-rate) and impressions-to-chapter-1-completion (how many people kept reading the book past chapter 1, which tells us if the banner was portraying the story correctly).
After making multiple banners for each story, the one with the highest metrics as per above would then become the default artwork to display on the GALATEA app.
