Many website owners are under the mistaken impression that website search engine optimization is only about how their website is designed and the use of internal elements. Thinking that in order to beat out their competition they need to continue to work on their website, adding content, adjusting metatags and other such things, they spend a great deal of money and time on that.
However, the fact of the matter is SEO is only about 20% internal and the majority of optimization is off site. This means lots of back links from “quality” websites. The word “quality” of course is subjective and there are many different definitions for this.
Having said that, your description metatag for each page is still very important. SEO expert Ian Scott points this out and why you need to spend some time on those tags.
