I'll be honest with you about this. If I were absolutely dedicated to making a living online here....I'd publish one per day no matter what, so long as I were able.
What would they be? Oh the'd be product hubs, and I'd just find things on amazon that I thought were "hot," and I'd publish about them...five hundred to seven hundred words, and some amazon, and some ebay ads if available.
Only reason I don't do what I'm telling you is I can not feign excitement about something....I only write what I want to write...and I do make money here...I know what works.
