Hi Morgan! Congrats! I have a couple suggestions about self-publishing promoting
1) If you want your book on bookbub, basically the promotion site that will make your book don't change the price or discount your book immediately or for a while (it's really, really hard to get onto Bookbub. I've never actually managed to get on there, but I've done my research). They want your book to not have changed price for a while (check the website for specifics). To get on there you'll need a lot of reviews, which brings me to #2
2) Do not be afraid to give away your book. Actually, give it to as many people who will agree to review it (only about 10% will actually review it, and be sure not to bug them if they don't review it). You can give away review copies on LibraryThing member giveaways, Goodreads Read 2 Review forums, you can pay for a book tour company for a 'review query' where they'll give out your book for you, or you can join a NetGalley coop for about $35-50 dollars a month (this will get you the most reviews, good and harsh), or you can query bloggers in your genre yourself. Please believe me, do not spam, you can and will be blacklisted by bloggers. And, never ever respond to a negative review. You can get bigtime blacklisted by the whole bookblogger hierarchy and be dead in the water for it. If reviewers reach out to you saying they loved your book, offer to have them be the first to receive the ARC of your next book (this builds a very loyal following). If anyone offers to beta read, take them up on it. Ask reviewers to cross-post, they're usually happy to do it.
To make review copies, convert your word file to html at this website:
Convert document online
Then download a program called Calibre for free. You can use it to make high-quality ebooks on your computer in all formats.
3) Join Triberr and regularly share relevant information for your audience of other author's. If you haven't already, set up a facebook author and twitter author page separate from your personal page. This is how fans will connect with you and make sure you connect everything to your website.
4) can you do basic video editing? You should have a program on your laptop for it. You can join a freetrail for videoblocks, audiobloblocks and bigstock videos and get stock video to use on a book trailer. Make it dramatic and only last about 1 minute. This is the best advertising tool on social media, especially facebook ads and Instagram.
5) put your book on ACX and query narrators directly. Make sure you search out 'royalty share and/or work for $0-50 pfh'. A lot of narrators are just starting out or they want to break away from non-fiction to fiction and want to build up their resume. Make sure you ask them politely to audition for your book because sometimes they have a great voice but are poor at audio-editing and you can end up in a contract with someone who's not a good fit. I find audiobooks sell more and for more and sometimes you can find an amazing narrator who will stick with you for royalty share. Once you have your audiobook completed, put it on audiobook boom! it will get you a lot more exposure and reviews.
6) Join author central and put up quotes from 5-star reviewers, especially if they're from a respected blog. I always ask the reviewers permission first, because it forms a trust relationship with my readership and because I like to respect other's work, but it's fair use to use 1-2 sentences. You can use code ★ five times for five stars (if they gave you five stars)
7) This one is 100% my personal opinion and many experts do not agree: Join KDP. I get more money and higher rankings from page reads than anything else. Also, don't underprice your book. Whatever price you put it at, that's what it's worth. I don't recommend putting it for $9.99 but maybe $3.99 or $4.99 and having it be available for reading online through kindle unlimited. That way people will read it more rather than buy it but then the rankings go up and people will start buying it, especially if you have 50+ reviews. Also, you can always go down in price but going up in price is frowned on.
Wow, I wrote a lot lol. If you don't mind, I might edit this and post it on my blog.
