Hey, guys! I never asked this question before, but how were any of you guys able to find paying customers for your books on third-party websites like Amazon? I'm conducting research as just advertising through Meta or Google Ads is not enough; from experience, only at least 1% of viewers respond to my ads, and they were often not paying customers. For free stuff like my work on Tapas, or apps on Google Play Store, said 1% of viewers do interact with my products.
Also, I have a feeling that my ads didn't always reach my targeted audiences or demographics, based on my book plots and genres.
