网站正在重定向与文档引用，它破坏了搜索引擎的结果(Website is being redirected with document referrer and it's ruining search engine results)

 如果你搜索谷歌的“纽约州海滩清理”，你会看到第一个结果是网站http://najomawi.com ，但标题看起来不适合这样的网站。 您还会注意到，如果您点击此链接，它会转到您的Nike鞋子网站。 只有在您使用Google结果链接时才会发生这种情况（我相信它会发生在Bing，Yahoo等）。 如果您将http://najomawi.com直接放入浏览器栏，它会将您带到正确的站点。 困惑，我检查了页面源代码（都有'查看页面源'和Chrome的检查器），发现这个...... 
 
<script>
    var s=document.referrer;
    if(s.indexOf("google")>0 || s.indexOf("bing")>0 || s.indexOf("aol")>0 || s.indexOf("yahoo")>0)
    {
        self.location='http://www.theredkicks.com';
    }
</script>
 
 我不知道这是怎么到达那里的。 它出现在主页的head标签中，即index.html。 没有PHP代码，没有其他JS，除了我知道的CSS样式表之外别无他法。 整个网站几乎都是静态的HTML和CSS表。 那么这是怎么做到的？ 我怎么能摆脱它呢？ 

If you search on Google 'new york state beach cleanup', you'll see that the first result is for the website http://najomawi.com, but the title doesn't look quite right for such a site. You'll also notice that if you click this link it instead takes you to a website for Nike shoes. It only happens if you use the Google results link though (and I believe it happens in Bing, Yahoo and others). If you put http://najomawi.com directly into your browser bar, it takes you to the correct site. Confused, I checked the page source code (both with 'View Page Source' and Chrome's inspector) and found this...
 
<script>
    var s=document.referrer;
    if(s.indexOf("google")>0 || s.indexOf("bing")>0 || s.indexOf("aol")>0 || s.indexOf("yahoo")>0)
    {
        self.location='http://www.theredkicks.com';
    }
</script>
 
I have no idea how this got there. It appears in the the head tags of the home page, which is index.html. There is no PHP code, no other JS, nothing other than CSS stylesheets that I am aware of. The entire site is pretty much static HTML and CSS sheets. So how did this get there? And how can I get rid of it?
