Hello After the penguin updates we are very concern with the directories that we submit to. Our directories are handpicked and all the directories have human moderator. Also we don't do bulk submission. We try to do natural link building by doing less submissions regularly. By this, Google wont consider our link building as spam. About out link building services I would like to inform you that we do Directory Submission Local Directory Submission Niche Directory Submission Article Submission Social Bookmarking Press Release Submission Link Prism (Prices and Plan on request) Web 2.0.
