I'm going to redo this series. Sorry for the mix-up before but this is how you can use Insights in Facebook advertising as an author. Even if you don't have any audience at all you can get some ideas to at least get you started before you get people to your website or whatever, if you don't have a mailing list. It is possible. You don't have to scrape users IDs or emails or any of that questionable stuff. Everything you need is here. You do probably have to have a few people that have read your book.
