Why is traffic not growing on my blog?

That seems to be the real problem. People are only interested in what they are interested in. Before you can get them interested in what you have to say, you need to start sharing the things that they want to hear about.

What are those things? Well, if I was selling baseball gloves, I'd probably want to share articles from places that had fielding tips. If I was selling drones, I might share great drone footage that others have posted or articles about FAA regulations that may affect the industry. If I was selling themed dog jewelry, I'd be sharing all kinds of things about dogs.

Who is your target audience (there is likely more than one)? Put yourself in their shoes and try to think of what they like. If you have trouble doing that, head to forums to see what they are talking about or visit the top sites in that niche and see what they are posting on social media.

Your goal is to grow your following at first, NOT to automatically think everyone is into the things you write about on your blog. Give them what THEY want to see. Maybe every 5-7 posts, mix in something of yours but if all you ever do is talk about yourself and your blog, you are the most boring person at the party.

Finally, when posting on social media, don't forget to give props to the people that wrote/posted the thing you are sharing - on Twitter especially. Use hash tags for popular terms and definitely don't forget to use someone's @twitterhandle when sharing something they created. It will automatically get noticed by that person who may follow you out of courtesy (it happens a lot). Because your Twitter posts are all being followed by them, they may occasionally re-tweet something you have shared, exposing you to all of their followers. Some of them will follow you, and so on, and so on ...
