Which is best for ranking : Link Building or Content

As everyone is aware of link building and content writing, what these are. Most of the people think content is king, but in what ways don’t know. I also heard that content is king but totally I am not agree with it. Both Link Building and Content Writing have their specific places. You will find its answer here,
Content Writing helps website to tell visitors about your website and It describes services/products of website with a professional edge. Content Writing can only be done when you are fully prepared to write with mastery in grammar on a particular topic. While writing content on any topic, content writers target keywords as per the page topic or service to help website rank higher in all major search engines like Google, Yahoo and MSN. As everybody knows that content may not be updated after a week/year. Content is updated one time or two times but no more than this. If you are doing such things then you are no more going to rank higher and search engines will not rely on your website too. To keep your website ranked higher in search engines you need to do some stuff on link building.
Link Building helps website to keep ranked higher in search engines for a long time. This process of linking your website to other related websites tells search engines to rely on your website and the result would be better rank for your website. As many as inbound links from popular websites you get chances of ranking higher in search engines will increase.
Content Writing can help you rank higher in search engines but no more than one or two months. To rank higher for a long time keep doing link building. Only link building offers long time business oriented results.
