Most every day I get an email or message on my Facebook page that begins with "how are you doing today?" or "I saw you book today" and the person wants to know what my inspiration was or for me to tell them about me book. I bit into it at first. I was over joyed that someone was interested enough and wanted to know more about me and my books. Along the way I learned that it was all a scam to get me to buy into what ever they were selling.
I'm a poor struggling author with hardly a penny to my name. I don't pay anyone to do anything I can do for free. And you should not either. I spend about an hour each day promoting my books. I rotate through them. Sometimes by season or as the mood strikes me.
You can make up your own ad and post it on Instagram, Facebook and X (Twitter) Remember to hit the repost button. Don't be afraid of technology. This is where technology is your friend. doing your own marketing and promotion will pay off in the long run. Don't pay someone to do what you can do with a little time and effort.
You can use platforms like www.Zeely.com to create ads and campaigns but they can get expensive. I tried them and did not get a good ROI. www.EBookhabitat.com is good and not a lot of money.
Here's an ad created by Zeely. I copied it and put it in my Blood Orange file. Now I can use it anytime I want to promote the book.
