But i doesn’t do anything with it. Please help.
robots.txt file is denying our Cards crawler (Twitterbot) from accessing your site. See the Troubleshooting guide for more help with this.
Thank you guys for quick reply. The problem is in server configuration that disallow any Robots. I don’t know that.Thanks. for another user: you can check how search robot’s see you robots.txt file just enter http://yoursite.com/robots.txt in browser address field. If your server has any limitation for seo you would see it.
