Hello, Please help me regarding the following errors which comes in my webmaster tool and I want that search engine not to attempt to visit these urls: 1. http://www.abc/fabrics.html?page=sh...page=flypage.tpl&product_id=245&category_id=1 2. http://www.ABC.COM/index2.php?option=com_content&view=article&id=17 3. http://www.ABC.com/index2.php?optio...output=pdf&product_id=243&category_id=1&pop=1 If I implement the following code in Robots.txt file: 1. Disallow: /?page=*& (Is by applying this in Robots.txt file we tell Search engine not to attempt this URL ?) 2. Disallow: /?option=*& (Is by applying this in Robots.txt file we tell Search engine not to attempt this URL ?) 3. Disallow: /index2.php? (Is by applying this in Robots.txt file we tell Search engine not to attempt index2.php URL?) I want that search engine not to attempt these dynamic pages. Thanks
