As per last panda update, you will get great benefits if you are getting back links from higher authoritative web portals with fresh and informative content. For the same, PDF submission would be the best option. You just need to provide me one article document with around 300 words and I will create the same in PDF formats. After creating PDF, I will submit the same in 15 high page rank document sharing websites. i.e docstoc, scribd, issuu, calameo, edocr,box, tagmydoc etc. I will take 3 day for submission as I will do it manually. In report I will provide you Excel report with carrying all approved URL and social bookmarks links if you have selected.
