http://www.webthoughtspot.org - Search engine optimization is not always easy to achieve because it is not simply one factor that you can tweak to obtain high rankings. Rather, it is a combination of factors. You have got the content. Content covers everything from the value that the content provides, grammatical structure to niche. Then you have to worry about the technicalities of search engine optimization that covers Google indexing, creating a navigable sitemap and more. Now imagine if there was one metric that you could use to control everything that comes into account when getting ranked on search engines. Yes, it is not a dream; such a metric exists. It is called domain authority.
