三类关键词的集合一般分为三类

三类关键词的集合一般分为三类：目标关键词、长尾关键词和品牌关键词。由于这三类关键字都是收集关键字，我们一般吃各种关键字，但长尾关键字一般是从关键字根展开的，所以掌握关键字根展开更为正确。
The collection of three types of keywords is generally divided into three categories: target keywords, long tail keywords and brand keywords. Because these three types of keywords are all collected keywords, we generally eat various keywords, but the long-tailed keywords are generally expanded from the key root, so it is more correct to master the key root expansion.
至于关键词的扩展，当我们第一次开始学习SEO时，我们必然会了解很多方法，包括：a、百度下拉框、百度相关搜索和选择方法，扩展深度3-4层。b.百度索引关键词工具的使用。c.百度竞价后台，可以下载关键词搜索列表。d.头脑风暴，头脑风暴，竞争对手研究。e.关键字开发工具，如金花、追逐词等，包括站长工具和爱情网站的关键字挖掘，可以用来扩展。也许还有其他一些基本的方法。我们不会逐一介绍他们。这里我们介绍一种非常实用的关键字扩展方法。与前五种方法不同，只要我们能根据前面所说的找到足够的根，这个方法就可以自动无限扩展。
As for the expansion of keywords, when we first start to learn SEO, we will certainly understand many methods, including: a, Baidu drop-down box, Baidu related search and selection methods, and the expansion depth is 3-4 layers. B. Use of Baidu index keyword tools. C. Baidu bidding background can download keyword search list. D. Brainstorming, brainstorming, competitor research. E. Keyword development tools, such as Jinhua, Chasing Words, etc., including webmaster tools and keyword mining of love websites, can be used for expansion. Maybe there are other basic methods. We will not introduce them one by one. Here we introduce a very practical keyword extension method. Different from the first five methods, as long as we can find enough roots according to the above, this method can automatically expand indefinitely.
具体的思想是建立一个excl表，水平和垂直地排列关键字根，然后将这些单词自由地组合在一个、两个甚至多个组中。当然，这可以通过函数来实现，并且可以很快地扩展。可能只需要几分钟。有了这个想法，你就可以自己操作了。
The specific idea is to establish an excl table, arrange key word roots horizontally and vertically, and then combine these words freely into one, two or even more groups. Of course, this can be achieved through functions and can be expanded quickly. It may only take a few minutes. With this idea, you can operate by yourself.
