Before I asked a question about how to rank high in Google I'm curious that What factors determine a good ebook(marketing related ebook).
to be honest, i think the term "good ebook" is an oxymoron. being here is putting you in the better direction
anybook that can really do as they claimed is a good ebook. if it say "you can make 100$/day" or "you can be an expert of photoshop in 10 mins" the reder should suppose to be able to do it as well.
