[转]wordpress添加keywords和description

昨晚搜了搜wordpress的seo方法,一直想为自己的博客添加关键词(keywords)和描述(description),昨个搜到了一个方法,已经试验成功。现在共享一下,代码来自李清海’s Blog,感谢!!!

将以下代码用文本文档utf-8格式保存(否则中文部分会有乱码),然后再wordpress后台找到header.php,将所有代码覆盖粘贴。就哦了。keywords和description自己修改即可。

 

<?php
/**
 * The Header for our theme.
 *
 * Displays all of the <head> section and everything up till <div id=”main”>
 *
 * @package WordPress
 * @subpackage Twenty_Eleven
 * @since Twenty Eleven 1.0
 */
