Google changed the search engine market in the ’90s by evaluating a website’s backlinks instead of just the content, like others did.
Updates like Panda and Penguin show a shift in importance towards content.
Will backlinks lose their importance?
Remember though: While links are used in ranking, using them to trick search engines into thinking that a site is relevant would violate our guidelines:
Back links will have its importance but it will not be the only factor for ranking , on page optimization will be the key factor.
1.Page Name
2.Titles
3.Descriptions
4.Heading Tags
5.Content
You need to get the above sorted first before you go on and build links.
