响应头 VS 元标记

2022-01-17 00:00:00 http-headers html seo

我可以在元标记或响应标头中声明一些信息，例如编码和语言.
我的问题:对于 SEO 和旧浏览器，最好的方法是什么(可能两者兼有)?

I can declare some info, like encoding and language, in meta-tag or in response-header.
My question: what the best way (maybe them both), for SEO and old-browsers?

元标记示例:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

(PHP) 标头示例:

(PHP) header example:

header('Content-Type: text/html; charset=utf-8');

什么更好?

推荐答案

Meta http-equiv 只不过是个笑话.当用它指定 Content-Type 时，只有 charset 部分才算作任何事情，而且只有当真正的 HTTP 标头未能指定编码时.

Meta http-equiv is little more than a joke. When specifying Content-Type with it, only the charset section counts for anything, and then only when the real HTTP headers fail to specify the encoding.
