Find some nice long keywords you know something about, and then, as they say - just do it! You don't need to keyword stuff, you don't need to tweet and facebook, you need a list, or a blog. You don't need to have multiple degrees. In fact you don't need to be a native-English writer.
What you do need to do is write. A lot. Really until you have a 100 hundred pages up on Wizzley you really don't have enough data to know what you are doing.
I can't promise - but I'm fairly confident if you use the approach I've described here - after 100 articles at least some of them will be making you money.
There is no perfect right or wrong answer, and this is definitely not a comprehensive guide, but really SEO writing is not as hard as a lot of over-paid SEO consultants would have you believe!
