“Send a goody bag (plus your book, obviously) to a restrict number of bloggers and ask for a sincere review”

If you are talking about getting reviews on Amazon, you’d better read the terms and conditions again. Amazon prohibits “Offering compensation or requesting compensation (including free or discounted products) in exchange for creating, modifying, or posting content.” https://www.amazon.com/gp/help/customer/display.html?nodeId=14279631

You are still allowed to send ARC reviewers your book for review, but you cannot send them other “goodies” to incentivize a review.

“Book authors and publishers may continue to provide free or discounted copies of their books to readers, as long as the author or publisher does not require a review in exchange or attempt to influence the review.”
