I am using Heroku to host my rails app and I have created a custom domain for the app at www.luminoto.com.
I just did a search for "luminoto" and I see that the herokuapp domain (horschgallery.herokuapp.com) is popping up.
Should I just create another domain in webmaster tools and use robots.txt to remove the Heroku domain from search results? Or will this in turn remove the Luminoto domain as well?
Also does Google think that Luminoto is duplicate content or a cloned site?
