One of my friends, selling backlinks . He has network of 240 websites. 2 PG8 and and over 70 PG6. So he is ready to work with me and start developing website and start SEO and ranking in on google. Do you think is good idea to start witn amazon website and using his source of links to rank it? Or maybe someone else has other idea of monetizing his network. He is already selling backlinks but is not doing other monetizing methods on that network.
