Offer easy tips for any problem and your readers will return every time they need some advice.
Expressing something is the trick. Getting into reader's shoes matters as we write.
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.
