I am a former professional golfer currently working on a series of golf instruction books. Previously, I have written a smaller series of golf instruction books that I sold on KDP to moderate success (sold around 2,000 copies in a couple years). These new books are going to be longer, better, and priced at $5 per book.
My question - What methods would you recommend to market these books? I will be selling them on Amazon as well my own site (that I will be making soon). While I played golf professionally, I did not reach a high enough level to have any name recognition with buyers. Potential buyers will not know who I am, so I will need to quickly demonstrate my expertise so they will trust me and want to learn from me. I am highly confident in the quality of the books, thanks to my golf knowledge and writing ability. However, getting them in front of the right eyes is where it gets tricky.
Thoughts on marketing channels that would be worthwhile for this kind of venture? Thanks for your time -
