Hello, Daily I write 2-3 post on my blog in the footer and submit to the social bookmarking networks (digg, stumbleupon, mixx, reddit, and polish one) And once I get pretty high indexed like second place in phrase "world's biggest wave breaks" , a few days later it turns out that this page is no longer anywhere in search results. Cliking site:myfooterblog.com I had few days ago 135 indexed things and now 129 ? Is G treating me like a blackhat positioner? Are those penalties? Check my meta in source of any page. Anyone had same experience? How I can prevent that, becouse on bigger scale it is not so good?
