I don’t claim to be an expert on ebook sales, neither do I sell many thousands of copies; but I do receive a variety of emails relating to the subject, and I often spot frequently missed opportunities for sales and some rather more obvious reasons why books don’t sell.
EDITING. The single most important process of publishing a book is structural editing and proofreading. The lack of consistent, industry standard editing will kill sales in record time. Readers can forgive a smattering of minor mistakes throughout an 80,000 word novel, but if the first thing they see when they look inside the book sample are glaring grammatical errors – then there’s little chance they will buy. It’s a false economy to skip the editing process simply because your sister said it was ‘ok’. Or someone you met in a Facebook group said they’d edit the entire manuscript for £100. Only employ a recommended editor with a good track record and be aware there are many, many plausible fakes out there. Be super critical and don’t publish too soon.
COVER. The cover can and should work in a number of ways to help sell your book. Mostly it needs to match the content and the expectations of the genre – ie: not a photograph which you happen to like and may be related to the material in some vague way, but means absolutely nothing to a prospective reader on the other side of the world. Do some research and look at other books in your genre. Unless you have an eye for design, understand book marketing, and own the relevant software to be original and creative; pay someone who does. Of course, it’s perfectly possible to make your own cover with free software through Amazon’s publishing platform or something like Canva, but if the end result looks homemade – and you want to reach beyond friends and family – then consider the commercial impact.
FONT. Often overlooked, but the font is a vital bit of selling kit. Nothing screams homemade more than a bog-standard font scrawled across a third-rate cover image. If the cover and the font look third-rate, then the reader is fully entitled to presume that the content is much the same. Do the research: you will not find a loopy font on a cold-blooded thriller. Consider the impact of this and apply accordingly.
FORMATTING. If you can’t handle the formatting, then please pay someone who can. It might be the best story ever and perfectly well edited but if there are blank pages, irregular indents, or oversized margins, then after a while it just becomes too irritating to read. Your text needs to look consistent on a variety of screen sizes.
BRANDING. If you’ve got all the above in order then do also consider branding. If you write across different genres this can be difficult but covers which are easily recognisable as one of yours, do help follow-on sales – so at least consider keeping the font of your author name consistent. Four or five cross-genre books with variable cover styles are notoriously difficult to sell. Same applies to using more than one author or pen name. This is why traditional publishers like material which is easily branded to match their current list. It’s easier to market and sell, and the reader knows what to expect.
