Hi, i have a old forum (20k members)...the forum and the topics rank very well..every topic is crawled after a few mins and indexed. the forum has some subfolders /wiki/ + /help/ etc. All this subfolders doesnt rank anymore. I have checked already htaccess and robots.txt settings. i have checked header status by google wmt. i have linked from other sites to the subfolders..bookmarks and strong other sites..nothing helps. when i use a direct snippet from the content of the subfolder and put it into google, i am arround site 10...in short..my subfolders dont rank for no content and no meta title...it looks like a filter or penalty but like i said, the forum ranks very well.... any ideas? ps: no i dont made fast linkbuilding or something like that...its a old good domain and i dont get it whats happend...the content on the subfolders is unique for sure! tx for help...
