AMS is my major tool. It works for my books. Nothing else does.
BookBub featured ads shouldn't be on the list, since we don't have the power to get them at will. Similarly, neither should "Getting a contract and large advance from a big New York publisher." When it's up to somebody else to decide, it's not a tactic. It might be a long-term goal, but that's all.
I can't stress strongly enough that YMMV. I've tried many tactics that work like gangbusters for other people's books but have not worked for my books. Even AMS ads don't work on books that are hard to categorize or in totally obscure niches. Which some of my books happen to be.
In three years doing this, I've tried everything on your list, plus several more things. Only AMS ads have produced a profitable ROI for my books.
