Using social media to promote blogs in my opinion, is always helpful. Although I think almost all social media is beneficial, I think Facebook is the most productive. For some people, they won’t post or publish certain things on their social media to keep a theme or just because it’s not relevant to what they normally talk about. With Facebook, there are, usually, no limits to what people post. I always see the most random posts on my feed and they are always from different people. People will share whatever they feel like regardless of what they “normally” post.
I also think Facebook would be the best way to promote a blog because there is a larger variety of people on Facebook. For example, if I asked my mom to share my blog, she would do it on Facebook because that is the only form of social media she has. But when she shares it on Facebook, all of her friends will see it, as well as all of my friends if she tags me in it. I think if you want something to be seen by a huge audience, Facebook would be the best way to share it due to the amount of people present.
