Unless you are an established website like BBC or Wikipedia, you will not get high rankings or good backlinks simply by writing great content. Backlinks are a key component in how Google (and by extension the other search engines that don’t quite have as much of a market share as Google) assesses a website’s eligibility to be placed higher up in the search results pages. You can have a website with the best content, the best design, hosted on the fastest servers, and have all the technical SEO aspects perfectly taken care of, but if your website don’t have a single backlink pointing to it, chances are it will be ‘invisible’ in the search engines. This is undeniable.
