All too often, I’m afraid to say.
I don’t often buy books because I’ve seen an advertisement (unless you count buying a book from the BookBub newsletter … which I don’t count, because that’s an email, not a social media promotion).
I’m most likely to get inspired when I see a new book available from an author I’ve previously read and enjoyed, or when an author, reviewer, or reader recommends a title.
I am less inspired by random posts from authors I’ve never heard of in genres I rarely read. (Big surprise, I know.)
I am 200% not inspired by social media book promotions in groups that don’t permit self-promotion. It’s always clearly stated in the rules, but it seems a lot of writers (even Christian writers) don’t or can’t read and obey group rules.
So that’s me and book promotions on social media.
