I blog three times a week. Monday, Wednesday and Friday. I started out posting Monday to Friday but it was just overwhelming and left me no free time for anything else.
I try to blog at least 2 times a week. If I where making money off my blog I am sure it would be more than that and maybe some people think more is better but for me, i just go with my own flow.
I attempt to do one longer, higher quality post each week and at least 2 smaller posts. I couldn't imagine blogging daily.
When I first started my blog, I was going to try and blog a few times a week. I'm now a little bit hooked and have been writing daily lately.
