Where to put robots.txt file?

Question

Where should put robots.txt?

domainname.com/robots.txt

or

domainname/public_html/robots.txt

I placed the file in domainname.com/robots.txt, but it's not opening when I type this in browser.

Where the file goes in your filesystem depends on what host you're using, so it's hard for us to give a specific answer about that.

The best description is: put it wherever the index.html (or index.php or whatever) file is that represents your homepage. If that's domainname/public_html/index.html, for example, put it in domainname/public_html/robots.txt.
