The first thing I had to learn was that my silly little personal stories were worthless commercially. I think you have to be famous to have folks want to just hear you talk, LOL!
After figuring out that actual information is what is valuable so far as commercial writing goes (DUH!) -....I still didn't have a clue as to how to put together a decent hub.
Someone suggested that I submit one of mine to the Extreme Hub Makeover Forum, and I did, and reading the suggestions of the people in there....taught me most ..um...ALL the little that I know that is worth knowing so far as on page SEO or page layout.
