How soon is too soon to reveal your next book cover, posting it on social media and your website/blogs? Some say hold off until a few months before the pub date, at least until review copies are mailed out. I was told by one publisher that if you reveal the cover too soon, readers will get use to seeing it, and then if they see it again some months later around the time the book actually comes out, they'll associate it with an older title. There are some authors who have not unveiled the actual cover until pub day, even displaying a generic cover on Amazon and other sites. Others say it's best to debut the cover early on and get it set in a reader's mind so that they bond with the visual and look forward to the on-sale date.
What's your opinion? How many months prior to release date do you unveil your new cover?
Also, here's a great, informational blog post on the same topic by author Jody Hedlund. She gives several important pros and cons that I found to be very helpful. http://jodyhedlund.blogspot.com/2011/02/when-should-authors-release-their-book.html
