Welcome to the Q&A Forum

This is my website: http://goo.gl/Brekn It was related to health niche. I am good with the serp for the last couple of hours. I am in top for the keywords: cure for piles, hemorrhoids treatment, natural hemorrhoid treatment. My main keyword is hemorrhoids treatment. And has recently added this page, http://goo.gl/SXNtX This page has some dupe content, as content writer was busy i have copied the content from other sources. Does this have any effect? I have not added this page onto homepage as i dont like google to index it until my copywriter writes the content. Dont know what happened, in the last few hours i lost my serp to no where. Can anyone tell me what happened to my site. Did i done anything wrong? In the last week i have added a link to my ebooks related site. Does this affected my serps? Or did the Google recent change http://googlewebmastercentral.blogspot.com/2012/01/page-layout-algorithm-improvement.html Has any effect on my site? Awaiting for your replies...
