Welcome to the Q&A Forum

Hi guys my site: www.dorchdanola-netbutik.dk is a e-commerce store, and generally we have many links on all pages because of the many products and categories. Im not sure if this is actually bad or good? I've been told that it will definately harm my site when google crawls it. The thing is that google visit my site often and I still have good pageranks in google. So does it actually harm my site having all these products and categories? And what can I do about it if google see every page as duplicate content? I also link to my social pages like FB, G+, e.g. Should I put rel="nofollow" or rel="me" on these social links? Thanks guys!
