I'm a web designer with about 50 clients. All of my clients' sites link to me with my chosen anchor text. My question is, On my company website I want to link to the sites I designed but I worry if I give a reciprocal link to my clients' websites then I will lose some SEO juice with Google. Does adding a rel="nofollow" help me? Am I worried about nothing? What's the best way to solve this problem?
