Okay, so I understand aggressive link-building is only beneficial in the short term, however; I look at sites in the top of the serps and the ones that are dominating are authoritative sites. I rarely see light niche sites ranking..If anything, authoritative niche sites are the way to go.. I also notice that, sites at the top of the serps are ranking with single digit backlinking even for competitive keywords. [Yes , i know you are able to hide your backlinks]. I am still a noob but I think ranking is no longer back-linking dependent, but I think On-page seo has become stronger... and basic overall site structure has become stronger... I'm probably late to this "epiphany". Any input appreciated. So is link building dying?
