I'm on track to release the first three books of a series - all at the same time to make a big splash. I have no mailing list or large social media presence, so I probably represent a lot of people who are trying to launch this thing. I'm coming out of nowhere.
I've been in contact with BookBub (BB) and BookFunnel (BF), and have reached a way to use both to distribute my ARCs via a BB Ad that links to a BF bundle 'download' page that has all three links to the book pages at BookFunnel that in turn link to their pages at Amazon. (BB would not let me link to a BF page that collects emails - I'm okay with that for this effort.)
I'd run these ads starting about 10 days out from the launch date, with the books on pre-order so I can link to their pages in the BF download page. In the ebook itself, I'll include a link to its page at Amazon and also make a plea for a review - both at the front and end.
I've identified three books as comparables that I want to use to tell Amazon that they should match me to those readers:
Ready Player One - Ernest Cline (Virtual reality and a game - a common theme in all three of the books in this list, as well as mine.)
Warcross - Marie Lu (Does a brilliant job of bridging from science fiction to the romance readers.)
The Eye of Minds - James Dashner (Also wrote
The Maze Runner series, so this is also a link to
The Hunger Games and
Divergent readers.)
If you go to Bookbub and set up an ad, you'll see that there are about 40,000 total followers of those three authors combined, and about 110,000 readers. (See David Gaughrans's posts and book to see the minimal difference.) BB ads are served to the readers number.
I plan to run three BB ads, each one targeted at one of the above authors. Here's the one for Ernest Cline -
Ready Player One:

Given that you are a fan of
Ready Player One, would you click on the ad?
(The other two ads would replace RPO with the relevant title.)
