Has anybody found success with simply building quality content around an existing page, to increase it's rank, without building external backlinks? So say I had an article on the health benefits of bananas ranking in 38th position on Google. I'd then create a few more articles: 1) X Foods that can make you feel happier 2) X Fruits that can give you energy 3) The importance of potassium These 3 articles then link to the health benefits of bananas, as they relate to it and it's good for the visitors. Can continually doing this (doing 4,5,6,7 etc articles and linking back) be enough? Should internal linking be exhausted before then moving onto backlinks?
