I add my blog in google webmaster tool There is an error Crawl errors : Restricted by robots.txt 1 That is the error can any one tell me what is it and how can i improve it?
robots.txt is used to restrict indexing of some places in search engines. if you dont have restricted place you can remove it or allow the crawler . you can do so by generating a robots.txt from the webmasters tool by navigation to the crawler access option.
FTP into your web directory and look for a file named "robots.txt." There are some online robots.txt editors, but you have to give them your website's/blog's username and password for access. I'm not sure you'd be comfortable doing that.
