Originality - Focus more on the originality of content and on a consistent basis. It is a habit you will need to cultivate.
Include data in blog posts. It makes the post more interesting and informative to read. It makes people stay longer on your pages and even share your content.
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.
