Since part of our mission is to help each other launch our books post KS, let me report on how Different Lee did on its first day (and the early hours of the morning today).
After less than 24 hours, it's sitting at 10,804 in the paid store and is at #36 in its best subgenre. I'm not even sure that reflects all the sales and yet. They're all on my dashboard, or I wouldn't know about them, but some of them haven't made it to the month-to-date unit sales page, and usually they don't seem to affect rank until they get to that page, though I can't be sure.
Unfortunately, I'm not one of these hyper-organized people who has promos going the very first day a book launches. I couldn't be with KS anyway, because I wouldn't have known when I was going to launch, and I didn't want to wait until later just to book promos in advance. I did spend most of yesterday booking promos--the thread I posted the link to was very helpful--but I had nothing running yesterday. I'm not even posting about it on social media until today.
Part of that momentum is undoubtedly due to you folks, so thanks again. However, the number of sales and borrows suggests that I must have gotten some response from my nominators. Early sales had been good (that partly was realistically probably all you guys, since nobody else knew about the book yet), but I saw a noticeable escalation in the afternoon, after Amazon put out the email to the nominators (about 3 pm my time). KU action also spiked, and when I checked this morning, the bulk of it was from Different Lee.
In the interest of full disclosure, I may be looking for reasons to think all the effort I put into the KS campaign was worth it, so I have a built-in bias. That said, the numbers do suggest that the effort is making at least a little difference in the strength of the launch. None of my earlier books got off to as big a start as this one (or even close).
In the interest of science, I probably should have let it sit a couple of days without doing anything else, but having a sense of how early it is to hit the ground running with a new book, I didn't. The AMS ad will kick in any time, I'll be tweeting and posting, and my first outside promotion (Sweet Free Books, which also advertises discounts and will take new releases) is today, so it will be hard to tell after this point how many sales are coming from what.
If anything else noteworthy happens, I'll be sure to report out. (While I've been typing, the book dropped a thousand in rank, and the remaining sales still haven't gotten to the monthly page yet. Amazon is being laggy is always. It didn't register any change in author rank yesterday, but today I'm up about 25,000 slots.)
