<meta name='twitter:card' content='summary' />
<meta name='twitter:url' content='http://www.example.com' />
<meta name='twitter:title' content='Article/Site Title' />
<meta name='twitter:description' content='Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam non elit ac dolor dictum gravida a a neque. Nunc posuere aliquet lobortis. Etiam nec mi sed ipsum tempor tristique.' />
<meta name='twitter:image' content='http://example.com/image.jpg' />Google+ defaults to standard meta information or Facebook's Open Graph tags to pull information on sites, however, to specify for Google+ you can use itemscope, itemtype, and itemprop tags on the body and element level. More information and examples can be found at http://schema.org/docs/gs.html. Examples:
<body itemscope itemtype='http://schema.org/Product'>
<h1 itemprop='name'>Product Name</h1>
<img itemprop='image' src='http://example.com/image.jpg'>
<p itemprop='description'>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
</body>Use custom meta tags to store data that you need in Javascript, instead of hard-coding that data into your Javascript. I store my Google Analytics code in meta tags. Here's some examples:
<meta name='google-analytics' content='1-AHFKALJ' />
<meta name='disqus' content='abcdefg' />
<meta name='uservoice' content='asdfasdf' />
<meta name='mixpanel' content='asdfasdf' /><meta name='microid' content='mailto+http:sha1:e6058ed7fca4a1921cq91d7f1f3b8736cd3cc1g7' />
