Busy people bombard

Respect your readers. They are busy people bombarded everyday with digital messages asking for their attention. Respect their time by making your content easy to read and valuable to them.
If your content gives them something that makes them sound smart in front of their peers they'll keep coming back to read more.
Be good at social media. If you aren't, no one will read your blog, not even your mum.
Blogging is a long term project, forget sudden fame, it's not a sprint it's a marathon. You also need to be a champion boxer, because you will get punched... a lot.
