What is a good metadata title ?

Meta titles should be short. It is best to keep them under 60 characters (spaces included). We recommend to describe what the page is about in the beginning of the title and add the name of a website or company at the end. Using keyworded meta titles is a good way to give signals of relevancy to search engines. Only include keywords in the title if they are also included in the body content of the page. Only optimize a page with keywords for which it is relevant. Google relies heavily on the title of a page and its relevancy to the content on the page to determine its appropriate ranking.
