I do not know it is Three way link or not:The company who conducts SEO for our company, they build link for our site though we do not have link page, so I guess that they have their own websites to exchange links.A (my website)B (Their website)C (Websites link to us)B link to CC links to AA not link to CIs it three way link pattern? if so, how can we tell the SEO company to stop that? If I tell them (SEO company) put the nofollow tags on their site (B)to all the sites that link to us (A) or use robot text to block those link page. Will it fix the problem? Tks
