Metadata: Hide entry titles

I am interested in hiding individual entry titles in the metadata so that an entry title doesn’t show up as the metadata title for Google, Facebook, Pinterest, Twitter, LinkedIn, etc. The appropriate Open Graph tags have already been implemented into my HTML's *head> portion. However, my front page "title" (which is a quote) continues to appear as my main title on search engines and social networks. The title of the entry (which is a quote) will override the metadata tags I have included in it. Is there a way to tell browsers not to read it that way? It was a pleasure working with you! Barren
