I believe you should post links to your blog posts with some catchy comments, post some interesting images with clear and contrasting colors, videos, infographics, ask people for their opinions, engage in different discussions, join some groups for bloggers on Facebook, or groups with your target group of people and engage in discussions there, pay for a sponsored post on Facebook, just to give your page a little kick off start (just make sure to, before you do that, have a lot of interesting content on your page; otherwise, I don't think people would be interested in following you.
I hope it will help you,
Thanks,
