LawsOfRobotsTxt

1. A robot may not index staging servers
2. A robot must obey the sitemap
3. A robot may not injure SEO or, through inaction, cause SEO to come to harm.

Add this line to your application's Gemfile:

gem 'laws_of_robots_txt'

And then execute:

$ bundle

Be sure to remove public/robots.txt, if it exists

LawsOfRobotsTxt installs a rack middleware into your application which renders a different /robots.txt based on the request's domain.

It looks in config/robots/ for a file named <DOMAIN>.txt, for example, config/robots/www.example.com.txt. A server restart is required to pick up changes.

If no file exists for the requests domain, it renders a default

# Robots not allowed on this domain
