关键词优化在SEO优化中占有着非常重要的位置，很多SEO操作者都在考虑应该怎么合理的优化自己网站的关键词，在优化关键词的之前，首先我们要把我们的关键词分类，按照你关键词分类的标准，安排关键词的优化步骤，制定关键词优化计划，下面是我对关键词优化的建议：
一、不同网页优化不同关键词
其实这个很多的SEO培训机构都会给出合理化的建议，比方说你网站的主关键词要用网站首页来优化，主关键词一般选着3-5个，长尾关键词用文章页来优化，我的建议是一般一个文章页优化只一个长尾词，但是这个并不是很严格，但是最多不要超过3个，因为文章页的权重是有限的，如果太多，就会减少页面权重的。
二、关键词的突出度
很多SEO培训老师都在讲，关键词应该出现在网页的
标签和<meta>标签中，但是很多人确实不知道原因是什么。其实关键词出现在这两个标签中的作用就是突出关键词的位置，搜索蜘蛛当抓取一个页面时，是从上到下顺次读取代码，他第一个抓取到的文本，他就认为非常重要，所以你的关键词越靠近网页顶部越好。</p><p>三、关键词的密度</p><p>关键词的密度就是说，某个关键词出现的个数占网页全部字数的比重。很多SEO教程或者SEO工具都建议关键词的密度在2%~8%之间，这个只是猜测，到现在为止并没有一个任何一个人可以说出关键词的密度到底是多少，我们不应该刻意的去关注关键词的密度，我们应该让关键词的出现顺其自然，也不要去运用“黑帽SEO”方法去堆积关键词。</p><p>四、关键词的出现的频率</p><p>关键词出现的频率就是指这个关键词实际在这个网页出现的次数，在百度更新算法之前，百度会注意关键词的频率，但是只从对关键词堆积的作弊方法出现解决方法后，算法已经对关键词的出现频率有了新的算法。我们咋I写文章的时候那就一定要注意关键词出现的频率了，一定要让关键词出现的合乎常理。</p> </div>
