Welcome to the Q&A Forum

Hello, I have around 100,000 Error pages showing in Google Webmaster Tools. I want to block specific components like com_fireboard, com_seyret,com_profiler etc. Few examples: http://www.toycollector.com/videos/generatersslinks/index.php?option=com_fireboard&Itemid=824&func=view&catid=123&id=16494 http://www.toycollector.com/index.php?option=com_content&view=article&id=6932:tomica-limited-nissan-skyline-r34--nissan-skyline-gt-r-r34-vspec&catid=231&Itemid=634 I tried blocking using robots.txt. Just used this Disallow: /com_fireboard/
Disallow: /com_seyret/ But its not working. Can anyone suggest me to solve this problem. Many Thanks Shradda
