Write 6 - 500 word articles
I am looking for about a 1% keyword density (1 time for every 100 words) in the articles, a little more or less is fine, but the most important thing is that the article sounds natural and conversational and the information in the article will be seen as valuable not just fluff (junk). Don't want it obvious that we are shooting for these certain keywords. Don't "stuff" the keyword(s) in just to get 1% density if it sounds like the word is being over used. The reader is my first priority and SEO is my second. The reader comes first.
Where I have grouped more than one keyword together use them all in the article and the density just needs to be around 1% for all the keywords combined not 1% for each, make it sound conversational to the reader.
