As you start getting more experienced with advertising and analyzing your metrics, you may find that certain books or series are steadily profitable. If you’ve earned a consistent profit over the course of your first few months of advertising, then you can try marketing your most profitable books in other marketplaces like the UK, Canada, and Australia. This strategy tends to work best when you only run those ads to books that provide reliable metrics, rather than just guessing that certain books can sell better than others.
If you have multiple profitable books or series, then you can also consider trying Sponsored Brands ads. These campaigns work most effectively when you have multiple stand-alone books or series starters because Sponsored Brands show three books at once. For instance, if you have three significantly profitable series in the same genre, then you can run Sponsored Brands campaigns to display the first book in each series. This can give new readers the opportunity to discover each series through the ad and potentially scale up what’s already working well in your Sponsored Products campaigns.
