Hey fellow U.S. authors, I’m curious—what are the most reliable and effective book marketing services in USA that have worked for you? I see a lot of international services that look promising, but I want to keep my promotions targeted within the U.S. for now. I'm aiming to reach readers on Amazon, Barnes & Noble, and maybe some local outlets or U.S.-based review blogs. If you've had success with any stateside book promotion companies, newsletter services, or even U.S.-focused social media campaigns, please share! I’d love to create a list of tried-and-true services for U.S. authors who are on a budget. Your insights could help a lot of us out—thank you!
