Blogging is more about you writing your experiences than what readers want to read. To get the right audience, follow your heart and write what you actually go through.
Don't just type, talk to your audience. Blogging is way big a market on internet and people will like you if you do more than just providing information. Suggest, express, appreciate, criticize and have an opinion to build a relativity to a like minded audience. Make them feel that their visit to your blog matters to you.
Follow up on comments you wrote on posts. Continue the conversation. Bloggers enjoy engaging with their readers.
