How Often Should I Add Content To My Site?

Id say add at least 1 post per week, but make it good, unique, and really juicy. Keep the word count high, and SEO it properly..

As long your articles are unique and original, you can add as many articles as you want. Google loves unique contents so adding tons of articles won't really hurt you.

When in doubt, write now, post later.

Just concentrate on adding quality content and not how quickly you can produce it

Dropping my posts from 1 per day to 1 per week was the best move I've ever made. So instead of working 7 days for 7 posts, I'm working 7 days for 1 really high quality comprehensive post. (I feel better about back linking 1 high quality post than 7 mediocre quality)

I think there is a big misconception around that authority site = high post count. You can be an authority site with lower post count but extremely high quality content that people share with all their friends and talk about. Just my opinion but I'm sure others agree with me.

Also I don't do this for all my sites, only the ones in niches that I'm particularly interested in and love learning more about.

Every other day.
