Yes, you read it right penguin has gone bat shit. The update was inconsequential for me since none of my sites were affected, until now. Two of my niche blogs has been shat over by the penguin, last week. This update was supposed to be good for sites with well written original content with no overtly aggressive back link profile. Even cutts and half the "seo" blogosphere was going all ga-ga about how penguin will bring the pot of gold to sites that are good. I feel this is far from the truth. For example, I have two niche blogs that have 1. Original, informative and well written articles 2. Original tutorial videos 3. No bookmarks, web 2.0 or blog network links 4. The themes are original and custom designed. The blog are on EMD domains. The blogs are completely indexed. The only back links they have are from 3 guest posts I did on 3 other popular blogs in the same industry. The guest posts are original, informative and have only one URL link to my sites. Site A was jumping between position 10 and 16 Site B is new and was dancing between 11 and 18 All of a sudden, site A disappeared from top 300 results, last week and today Site B fell down to 80 and is fluctuating between 60 and 80. I have a hunch that Site B will also disappear tomorrow from the SERP's. In case you are wondering, the blogs are not in a competitive niche and some sites are ranking with crappy links.
