Do you really read excerpts when featured on blogs?
That depends on whether the blurb sounds interesting.
If the blurb sounds interesting then I'll read the excerpt.
If I like the excerpt, I'll add the book to the wishlist.
Would I visit a blog to specifically read an excerpt?
But considering how many books are available in every genre you can imagine now, an excerpt can go a long way towards making an informed choice on whether to spend the hard-earned cash, and take a chance on an unfamiliar author, or not.
