I am relatively new here and have been searching the forum before asking this so I apologize if this info is somewhere else. A few of best best producing sites all on page 1 of G got sent back to page 100 and further after the G update. I was wondering if anyone has had same experience, had advice, tools to use to bring them back from the dead. I did not have to do much backlinking to keep them there however, I did social bookmarking, youtube, and some articles. I am really new to seo software as well so if any of you could give me advice I would greatly appreciate it.
