1. Check what other blogs in that niche write about. Do some competitive research and look at what drives their success.
2. Create a plan of topics that you'll cover. Don't write about things people don't care about - that results in zero traffic (and zero business). Do some keyword research and find out what people are searching for, what topics they're interested in. Then figure out how your content is going to deliver and help answer those questions.
3. Set yourself apart! Figure out your unique angle, what's the reason someone would read your blog and not some other. Is it because of your quirky tone, expertise, experience, unique angle, etc.!?
