I have created website which is related to visa consultancy but didnt created robots.txt and then created one with minimal information on it. User-agent: * Disallow: / Can anyone help me to get right file with correct or better information in this. Thank you in advance
Your current file is disallowing everything. Is that what you really want? You do not want your site to be indexed at all? You can find a complete info on what to put in your robots.txt file here: http://tools.seobook.com/robots-txt/
Currently, the code you have written in your robots.txt file is disallowing all Search Engine Bots to crawling and indexing your website. If you are looking for the same then it is correct but if you want to robots text in your website and do not want to disallow any bot or page for the crawling, then go with the code that Robin wrote above. And it is not compulsory to add sitemap.xml file in the robots.txt file.
As other people stated, you are blocking off everything from being crawled. Without seeing the files you have on your server, I would suggest blocking any admin folder at a minimum. Could you post a bit more information so we can help you out?
