Good question!
Let's face it. Most studio's blogs suck. They either empty or filled with reposts of other people's content. BAD! WRONG! Content marketing is a topic all in of itself.
First, you can't rank for other people's content. If you just post an article from Yoga Journal you won't get any help from Google because Yoga Journal has already ranked for that content. To rank in Google your content must be original.
PLEASE NOTE >>>>>>
Blogging isn't a formal writing style. You certainly don't want to have a bunch of grammatical errors but it isn't a academic paper either. Relax and just write.
