I wonder if there is a default Robots.txt for Umbraco (7.5) websites. Right now, I created one with these items. Shall I add anything else?
User-Agent: *
Disallow: /umbraco/
Disallow: /umbraco_client/
Disallow: /css
Disallow: /Errorpages/
Disallow: /scripts/
Disallow: /Config/
Regarding CSS & JSS check this: https://yoast.com/dont-block-your-css-and-js-files/. I decided to cut them off lately.
Mine, always used with Umbraco instances, robots.txt file looks like this:
# robots.txt for Umbraco
