I have build up a biggish amazon site in less than 8 months, it currently sits at around 120 quality content pages ranging from 700-2000 words each. I have closed a deal with a very well respected content writer in my niche and the site will be growing by 1-2 article pieces a day , by the end of the year it should have around 500 total content pages that are highly targeted to certain keywords in the niche. The site already ranks for alot of its targeted keywords and a whole lot of longtail keywords with not much done on my part other than social sharing and link baiting. What would your strategy be on linkbuilding as the site will be massive in a year or two ? Im not into mass bulk backlink,bmr,scrapebox blackhat tactics. Would you point alot of links to the inner pages , category , homepage ? What links would be build and what methods would you use?
