HTML Meta标签知多少

Posted 2023-03-21

一、基本属性

标签常常被用来定义html文档的元数据或者HTTP协议的指向，这些元数据常用在SEO、HTML Pages or Apps on Mobile/Handheld Devices，该标签主要包括以下属性：
Attribute Description
Name Name for the property. Can be anything. Examples include, keywords, description, author, revised, generator etc.
content Specifies the property’s value.
scheme Specifies a scheme to interpret the property’s value (as declared in the content attribute).
http-equiv Used for http response message headers. For example http-equiv can be used to refresh the page or to set a cookie. Values include content-type, expires, refresh and set-cookie.

三、OpenGraph Meta标签

为了提高站外内容的传播效率，2010年9月，在F8会议上Facebook公布了一套开放图景协议(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。通过Open Graph把其他社交网站建构的网络给连接起来，将创造一个更聪明、更与社交连接、更个人化也更具语意意识的网络。

五、创建自定义 Meta标签

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:
1
<meta name="google-analytics" content="1-AHFKALJ"/>
2
<meta name="disqus" content="EEEE"/>
3
<meta name="uservoice" content="XXXX"/>
4
<meta name="mixpanel" content="XXXXE"/> 参考技术A <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="description" content="网页描述" /> <meta name="keywords" content="关键词" /> 常用的META标签就这三个，当然还有很多，这三个是基本的。第一行标明网页是UTF-8格式 第二行意思是网页的描述。 第三行意思是网页关键词，多用于SEO，写入合适的关键词方便搜索引擎找到。 参考技术B 你可以在网上搜索。
meta里面都是一些说明内容。
所以网上有很全的东西。
