Healthhype.com suddenly rank in Google only with tag, category or home page urls, but no more for page (article) urls. It happened to our last 15 articles like Diarrhea in Children with Rare Genetic Disorders site:www.healthhype.com url shows that the article is indexed but it doesn't rank nowhere. This happenned in ALL search engines: Yahoo, Bing, Baidu, Ask... Someone has solved the same problem with removing some code [<link rel="alternate...archives...>] from the header that pushed Google into a loop. What was added recently in healthhype.com header was favicon and one java script for changing the text size, but this code appears in the header of all articles, but only last 15 were affected.
