Raven supplies a total set of link building tools including a Links manager that helps you manage the link standing, contacts and tasks related to each link. Another popular feature of Raven is that it automatically alerts you if any changes have occurred on an active link, as an example, if the no-follow attribute was added, if the anchor text was modified, if the rank changed, or if the link was removed. Reports and info can be generated and downloaded.
