Hi everyone,
I'm looking for the best book marketing company to help promote my latest publication. With so many options available, I'm finding it difficult to decide which company to choose.
Has anyone here had great experiences with a particular book marketing company? What factors should I consider when selecting a marketing partner? Any tips on ensuring the company will effectively reach my target audience and boost sales?
I appreciate any recommendations and insights you can provide!
Thanks in advance!
