Here are the results of my advertising test at BookBub: “Belong” (ad 1) and “Courage” (ad 2) got almost exactly the same number of clicks, but hardly any clicks at all from Amazon shoppers. The vast majority of readers who showed interest by clicking either ad were Barnes & Noble customers (“Belong”) or, surprisingly to me, Apple Books and Kobo readers (“Courage”).
This supports my belief that writers who give Amazon exclusive rights to sell their books are condemning their works to compete with the almost infinite number of “products” sold by Amazon, while ignoring the truly dedicated readers who shop at Barnes & Noble and elsewhere, and who prefer non-Kindle tablets and e-readers.
When I launch a serious ad campaign for Waterspell Book 4 and the accompanying audiobooks, I now know where to direct my efforts.
