First step, figure out WHY you're blogging and make sure that comes across clearly in your content. Purpose = authenticity = trust

Then, figure out what questions people in your niche are asking (forums, Quora, Reddit can all be helpful with this. Also try answerthepublic.com) and focus on answering them in your posts. Figure out how you can add real value.

Then, post and post and post, consistently. Don't give up, you'll get there!

Good luck!
