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.

Write regularly; not too often or too rarely. Two to three blogs a week is a good frequency to maintain. Depends on the genre though.

Make sure you are interacting with your readers! If you are not doing so, your are not blogging.
