I have a SEO client for who I've been working for almost a year now. I used a broad mix of links like the packages (web 2.0, social bookmarks, profiles, social signals,...) you can find in the Buy&Sell of the forum + article links from local high PR domains. What can I do more to rank the chosen keywords? I don't want to overoptimize the anchors and also want to avoid a penalty. How do you handle long term SEO clients? Any suggestions or tips? Is 'hiring' links from networks a good idea?
