网站一夜关键词降为0

王柏元的博客疑似被百度搜索K掉，自上个月17号以来关键词个数一路走低，直到这个月降为0，昨天甚至通过“王柏元的博客”、“王柏元”这样的关键词我的网站不在前5名、甚至无法搜索到我的网站，初步判断的原因可能是我上个月解析的www.wangbaiyuan.cn到本网站因为疏忽没有实行301重定向到wangbaiyuan.cn，导致百度搜索认为我的网站被镜像。在未找到确切原因之前，我决定通过百度站长平台采取闭站保护，防止不明原因对网站SEO进一步产生影响。

闭站保护申请期间，百度要求被保护的网站要出于不能访问状态：全站HTTP状态码设置为404，或者将服务器关机服务器。通过域名不解析的方法是不能通过闭站保护审核的。所以对于虚拟主机用户不能切断服务器电源情况下，可以采用全站404的方式申请闭站保护。

新建如下内容的index.php实现全站404

你可以将原来根目录的原index.php文件改名，新建一个index.php内容如下：

<?
@header("http/1.1 404 not found"); 
@header("status: 404 not found"); 
?>
