More SEO and Social META tags for Twitter and Google

Here are some more HTML META tags I just discovered:

Twitter Cards

Twitter Cards (announced in June 2012) are extended tweets that can show more than just 140 characters. Here are META tags to add to your page HEAD section to help Twitter pick the right parts your site's content.

The twitter:card tag can be summary (for a news article, blog post, or text-based page), photo (for an image or picture), or player (for video).

<meta name="twitter:card" content="summary" />

The twitter:site and twitter:site:id tags let you identify your own Twitter username, and official Twitter user ID. Most people won't know their Twitter user ID. If you don't, you can omit that META tag.

<meta name="twitter:site" content="@YourTwiterScreenName">
<meta name="twitter:site:id" content="1234567890" />

The twitter:url tag is for a link to your page.

<meta name="twitter:url" content="http://www.YourSite.com/path/pagename.html" />

Other tags are pretty self-explanatory:

<meta name="twitter:title" content="Your Page Title" />

<meta name="twitter:description" content="Your page description." />

<meta name="twitter:image" content="http://www.YourSite.com/image.jpg" />

Google+ OpenGraph

OpenGraph (og) META tags help Google Plus pull the right information from your page, in case anyone ever shares it on Google+. These are pretty self-explanatory.

<meta property="og:title" content="Your Page Title" />

<meta property="og:image" content="http://www.YourSite.com/image.jpg" />

<meta property="og:description" content="Your page description." />

<meta property="og:site_name" content="Name of Your Site"/>

Google Search Thumbnails

Google also uses a thumbnail META tag to present small images next to its search results from your site.

<meta name="thumbnail" content="http://www.YourSite.com/image.jpg" />
