武汉seo:网站关键词密度控制在多少最合适

关键词密度对于关键词排名的影响是十分重大的,但是密度如何控制是非常有讲究的,密度小了可能影响排名效果,密度大了可能造成过度优化,因此,很多朋友在优化网站的时候都会有这样的疑问“网站关键词密度控制在多少最合适?”,本文就给大家详细讲解一下关键词密度的相关问题。

首先,我们要对关键词密度的定义有一个基本了解:

关键词密度与关键词频率所阐述的实质上是同一个概念,用来量度关键词在网页上出现的总次数与其他文字的比例,一般用百分比表示。相对于页面总字数而言,关键词出现的频率越高,关键词密度也就越大。

接下来,我们要知道关键词密度是如何计算的:

关键词密度计算就是关键词出现次数的总字符/页面中总字符数量,具体看下面例子。

例一:

关键词“seo”在页面内出现20次,seo所占字符3个,页面共有3000个字符,那么计算方法是3*20/3000*100%=2%,也就是说该词在该页面的密度2%。

例二:

关键词“搜索引擎优化”在页面内出现15次,该词所占字符6个,页面共有3000个字符,那么计算方法是6*15/3000*100%=3%,也就是说该词在该页面密度为3%。

总结公式:关键词所占字符*关键词出现次数/页面总字符*100%=关键词密度。

提示:由于用百分比表示,所以乘以一个百分之百换算单位,关键词密度是一个模糊概念并不绝对,这里的公式仅做参考,没有必要真的去进行计算。

那么,关键词密度控制多少比较合适呢?

其实关于这个问题是没有标准答案的,第三方工具给出的数据也仅仅是一个参考,一般是2-8%、3-7%比较好,具体多少大家只要做到自然合理,不刻意堆砌。

关键词密度过高会被惩罚吗?

显然,搜索引擎会很可能会识别为作弊行为。如果故意去堆砌关键词,被惩罚的概率比较高,所以还是不要铤而走险。而且关键词密度过高,用户体验也会比较差,自然会影响的效果效果。所以,无论如何都不要堆砌关键词。

关键词密度如何控制?

一般,我们可以通过图片的alt标签、a标签的title属性、简介、文字描述、h标签来调节关键词密度,有效控制关键词密度到最佳。

百度和谷歌对于关键词密度的重视程度:

百度非常重视关键词密度,在判断页面内容相关性的时候,会很大程度依赖于关键词。

谷歌对关键词则不那么重视,有时候关键词密度超过25%也依然能获得较好的排名。

关键词密度查询方法

1、站长工具关键词密度查询工具:http://tool.chinaz.com/Tools/Density.aspx

2、爱站关键词密度检测工具:https://tools.aizhan.com/kw/

3、当然还可以手动查询,或通过查看快照关键词会有黄色标记,再结合计算公式。

提示:不同工具计算方式不同,结果也不一样,数据也仅仅是提供参考。

总之,合理控制关键词密度到最佳比例是十分重要的,这样对于关键词的优化大有裨益,但是,我们也不要一味的迷信关键词密度,要知道想要把SEO做好,需要多方面综合把握。
