nofollow是什么?

nofollow 是html代码中的一个标签属性。一般用在以下两个代码标签中

<meta> 为html代码中的声明标签 <a>标签为常见的超级链接标签

        搜寻引擎的蜘蛛或者爬虫当访问你网站的时候 洛阳SEO 牛广 他们并不是一直在你的网址上爬, 可能它来的次数比较频繁,但是时间非常短暂。
       比如:  网站里有100链接,其中有10个网页里的内容或者链接对搜寻引擎是没有什么价值的,列如:网站的版权信息,广告,声明,联系我们等..  这些网页文章链接一般是不会产生关键字的排名的。而且在百度蜘蛛抓取是就会被进行消噪处理剔除掉 。 他们会消耗搜寻引擎抓取网站时间和速度。
     蜘蛛在你的网站上爬10秒钟, 一秒爬5个链接, 能爬50个链接。但是其中有5个链接就像我上面所述的没有用的链接 。这样就白白损失掉了蜘蛛抓取的次数。
     如果我们把那些没有用到页面或链接加了nofollow属性后,当蜘蛛再来爬行时,就引导了蜘蛛不要去爬行这个页面或链接,去爬有利用关键字排名的网页或链接。
