这是在阿里巴巴国际站看到的head部分:

<title>Manufacturers, Suppliers, Exporters & Importers from the world's largest online B2B marketplace-Alibaba.com</title>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<meta name="keywords" content="Manufacturers, Suppliers, Exporters, Importers, Products, Trade Leads, Supplier, Manufacturer, Exporter, Importer" />
<meta name="description" content="Find quality Manufacturers, Suppliers, Exporters, Importers, Buyers, Wholesalers, Products and Trade Leads from our award-winning International Trade Site. Import & Export on alibaba.com" />
<meta property="og:title" content="Find quality Manufacturers, Suppliers, Exporters, Importers, Buyers, Wholesalers, Products and Trade Leads from our award-winning International Trade Site. Import & Export on alibaba.com"/>
<meta property="og:type" content="site" />
<meta property="og:url" content="http://www.alibaba.com" />
<meta property="og:site_name" content="Alibaba"/>
<meta property="fb:admins" content="100002227819697,124207444332529" />
<meta property="fb:page_id" content="22437985072" />
<meta property="fb:app_id" content="124207444332529" />

 

Meta Property=og标签是什么呢?


og是一种新的HTTP头部标记,即Open Graph Protocol:
The Open Graph Protocol enables any web page to become a rich object in a social graph.
即这种协议可以让网页成为一个“富媒体对象”。
用了Meta Property=og标签,就是你同意了网页内容可以被其他社会化网站引用等,目前这种协议被SNS网站如Fackbook、renren采用。
SNS已经成为网络上的一大热门应用,优质的内容通过分享在好友间迅速传播。为了提高站外内容的传播效率,2010年F8会议上Facebook公布了一套开放内容协议(Open Graph Protocol),任何网页只要遵守该协议,SNS就能从页面上提取最有效的信息并呈现给用户。
Open Graph Protocol应用指南
参与到Open Graph Protocol的好处
  ● 能够正确的分享您的内容到SNS网站
  ● 帮助您的内容更有效的在SNS网络中传播

 

Meta Property标签的应用

  ● 按照您网页的类型,在<head>中添加入meta标签,并填上相应的内容
  ● 如果一个页面上有多个需要标识出的内容怎么办?
  您可以重复meta标签,将认为og:type 标签是每一段内容的起始处,

例如:

<meta property="og:type" content="video"/>
<meta property="og:title" content="五月天_突然好想你MV现场版"/>
<meta property="og:image" content="http://g1.ykimg.com/0100641F464AC21FF0B3ED00F48F151F43D4BF-5F0F-BD39-76EA-E5E20A1887C4"/>
<meta property="og:url" content="http://v.youku.com/v_show/id_XMTIyMTY5NzMy.html"/>
<meta property="og:videosrc" content="http://player.youku.com/player.php/sid/XMTIyMTY5NzMy&isAutoPlay=true/v.swf"/>
<meta property="og:width" content="500″ />
<meta property="og:height" content="416″ />
<meta property="og:type" content="video"/>
<meta property="og:title" content="五月天_突然好想你MV现场版_AA"/>
<meta property="og:image" content="http://g1.ykimg.com/0100641F464AC21FF0B3ED00F48F151F43D4BF-5F0F-BD39-76EA-E5E20A1887C44444"/>
<meta property="og:url" content="http://v.youku.com/v_show/id_XMTIyMTY5NzMyyyyyyyyyyyyyyyy.html"/>
<meta property="og:videosrc" content="http://player.youku.com/player.php/sid/XXXXXXXXXXXXMTIyMTY5NzMy&isAutoPlay=true/y.swf"/>
<meta property="og:width" content="600" />
<meta property="og:height" content="716"/>

● 安装SNS网站插件如人人网插件,同样会出现Meta Property标签,卸载后可以去除。?

 

使用Open Graph Protocol应注意

    meta property=og代码的功能并不等同于网页的meta name标签,两者针对的对象不一致,功能不同。
  如果网站上要使用Open Graph Protocol,那么,meta property=og和meta name、Title标签应同时赋值。
  比如某家B2C网站,<head>如下:

<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<title>Cool Gadgets at the Right Price - Worldwide Free Shipping - ******</title>
<meta property="og:title" content="**’sFacebook" />
<meta property="og:type" content="product"/>
<meta property="og:url" content="http://www.******.com" />
<meta property="og:image" content="http://www.******.com/logo.gif"/>
<meta property="og:site_name" content="******.COM" />
<meta property="og:description" content="CoolGadgets at the RightPrice - Worldwide Free Shipping - ******"/>
<meta property="fb:admins" content="100001422224225" />
<meta property="fb:page_id" content="241333394220"/>
<link href="/css/reset.css" rel="stylesheet"type="text/css" />
<link href="/css/default/all.16666.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="/shop.js"></script>
<script type="text/javascript" src="/scripts/all.16666.build.js"></script>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<meta name="description" content="Online shopping for cool gadgets at the right price. " />
<meta name="keywords" content="cool gadgets, cheap gadgets, free shipping" />
</head>

如果你用上了Meta Property标签,你得在后台设置好,不然,就是空白.
Open Graph Protocol对SEO的影响
  有些人使用所谓的网站质量在线检测,检测后结果提示Meta Property=og这段代码有问题,特别是一些SEO的检测,更是提示“特别错误”!然后删除Meta Property=og代码,检测正常。
  因此担心Meta Property=og这段代码会对网站照成不良影响。
  其实Open Graph Protocol并不会对SEO照成不良影响,相反,应用的合理,非常有利于网站的推广。
