HeadMeta

インストール

1. Upload the headmeta folder and its contents to your wp-contents/plugins directory.
2. Activate in the Plugins menu.
3. Add Custom Fields to your posts.

To use this plugin, you add key/value pairs in the Custom Fields section
when you create or edit a post or page. If you enter description or
keywords as the name of the key, HeadMeta will automatically generate an
appropriate <meta> “description” or “keywords” tag in the head of your
HTML.

If you need to create arbitrary <link> or <meta> tags, you can use
“head_link” and “head_meta” as the key. Whatever you enter as the value for
that custom field will be plugged into the generated <link> or <meta> tag.
For example, if you added the following keys and values:

KEY: head_link
VALUE: rel="seealso" href="http://example.com/movies/"

KEY: head_meta
VALUE: name="keywords" content="entertainment,movies"

This would generate two tags in the of the page when someone visited
the permalink for the post:

 <link rel="seealso" href="http://example.com/movies/" />
 <meta name="keywords" content="entertainment,movies" />
