I recently published a workbook for helping kids get organized called, This One's For You, Messy Kid. In order to get the word out, I:
Created an announcement in Canva and pinned it on my social media channels (Twitter, Facebook, and LinkedIn).
Added the cover thumbnail linked to the workbook's Amazon url to my email signature.
Told my close friends and family about it (100% of my sales, so far).
Donated copies to my son's 4th grade class.
Purchased 2 week's worth of Amazon ads.
I plan to bring a copy to my neighborhood book store, Park Road Books, with a quick link or QR code in case they would like to order some. 🤞
And this might be a shot in the dark, but I will mail copies to children's book authors and illustrators whom I think would get a kick out of it.
Promoting my workbook isn't a huge priority for me at the moment as I toil in the revision trenches. But these steps are simple and, other than the printing costs of the copies I'm gifting ($2.15 per book), they are free to carry out.
No matter what your circumstances, there is always a way to honor your work by letting people know about it. It just takes a proactive attitude, which I know you have, fellow writer!
