At article at NPR suggests that publishing houses are trying to collect data to provide a basis for determining if a book will sell well, or not:
Publishers' Dilemma: Judge A Book By Its Data Or Trust The Editor's Gut?
I have to admit at being surprised - my personal opinion, at present, is that is a book is structurally well-developed then it should prove to be especially engaging. By that I mean clearly show settings, stakes, and especially conflict, early on.
However, I get the impression that a lot of editors are focused on the quality of the prose.
So while some people will complain that the prose in Stephanie Meyer's Twilight is poor, I'd suggest it's a structurally accomplished book and therefore no surprise it was successful (though perhaps not so successful).
Interestingly, there's also a piece I came across at the same time about how publishers failed to spot the appeal of the Harry Potter stories:
Why were so many publishers unable to see the massive potential for Harry Potter when they first read it? - Quora
There are some interesting points suggested, though IIRC the first book originally started with a prologue used toward the end of the series.
Even still, it is a structurally well-developed story, with a superb use of conflict to generate sympathy for Harry under the Dursley family.
This is also a reason why I was really surprised that the beancounters at a Big 6 publisher turned down Jo Zebedee's Inish Carraig - IMO it is a structurally accomplished novel that has much in common with modern best sellers.
