I think most people would agree that having your work available in as many channels as possible is the best route. Amazon and BN have the lion's share of the ebook market. Yet, many authors of erotic romance find success on ARE and iTunes. At the end of the day, you have to do what is comfortable for you. You can deal with the learning curve of uploading your work to each channel or try to pay someone to do it for you. Personally, if I don't upload myself, I'd pay someone a flat fee to do it. I don't want to pay Smashwords or anyone else a percentage of my sells on iTunes and Kobo ten years from now. Don't be in a rush, outsource when possible. And unless you have hordes of people contacting you trying to get your books on iTunes or Kobo, they can get your books through Amazon or BN if they really wanted to read your work. The smaller channels are really for discoverabilty in my opinion. ARE is something you should be looking at for your particular genre though. I believe they allow you to upload like ten different formats of ebooks including epub and mobi. You need a publisher account.Toonldy said:
If I were you, I'd focus on ARE first simply because you already have files ready to upload if you are on Amazon and BN. Then work on the others.
