We recently launched a web app (http://www.buildlinkapp.com) that helps link building/marketing people build links manually and track link stages.
The web app improves link building team's collaborativity and productivity. That's what we think and we're currently using it on our online connection/link building, it works and helps us much.
Have you guys used any similar application before? Do you think such a system can provide value to the SEO/marketing team? Or do you have any suggestion on how to make it better?
