做SEO最重要的一个就是要学会如何搜索，这时可能会有人说往搜索框里输入文字难道还不会？普通的搜索肯定需要会，但是有一些特殊的搜索是SEO必修课程。下面就来介绍一下搜索引擎的特殊搜索——高级搜索指令
1 反链查询
百度搜索的反链查询 —— domain:
domain:cjzzc.com
360和搜狗的反链查询用的方法是直接搜索域名。
cjzzc.com
Google的反链查询用 —— link:
link:cjzzc.com
不过这些查询方法只适用于查询纯文本外链，对于锚文本外链还是查询不了的。一般对于站点的锚文本外链查询平台都是付费的，这里推荐简单免费版可以简单查看外链整体情况的majestic外链查询平台，后面会再介绍其他平台。
2 收录与索引查询
不管是什么搜索引擎统一用site:
site:cjzzc.com
site之后，部分搜索引擎还可以选择查看一天内收录、一周内收录、一月内收录和一年内收录，比如百度搜索引擎。
3 查询url中包含的特定关键词的链接
我们可以根据url中包含词，来判断我们优化这个词的难度，但是这个对于中文网站而言，几乎是用不到的。
指令为 —— inurl:
inurl:cuowu
就是指在搜索引擎中查询链接中包含cuowu的页面。
一般，我们是配合site指令来查询栏目的收录量，或者是查询我们网站的某一个或某些具有相似url的链接是否被收录。
比如超级蜘蛛池有一个栏目为url命名为 seo ，那么查询这个栏目下的所有收录的方法为：
site:cjzzc.com inurl:seo
或者是 inurl:cjzzc.com/seo
一般来讲，第一种方法更好一点，第二种方法虽然也能查出来，效果稍微差一些。
4 查找标题中含有某关键词的页面
我们都知道优化某个关键词，不一定非要出现在标题中，那么如果我们想让搜索出来的都是标题中包含了关键词的页面呢？那么我们就需要使用intitle：这个指令了。
intilte:超级蜘蛛池
这个指令的意思是查找标题含有“超级蜘蛛池”这三个字的页面，通常也被很多人当做是判断关键词难易程度的因素之一。如果这样子的查找到的相关页面数量还是非常庞大，说明这个词优化的难度还是非常大的。
5 搜索更加精准的关键词
一般我们来用减号 “-”来搜索我们需要的精准关键词。
比如我们要搜索“超级蜘蛛池”，但又希望不包括“超级”字，这样搜索出来的就是包含了“超级”和“超级蜘蛛池”的相关结果了。PS：减号后面不能有空格哦。
如： 超级蜘蛛池 - 超级
5 搜索完整匹配关键词的页面
Because of Chinese word, many pages may not contain a complete match keywords to search for us, so the quotes can help us find those perfect match keywords page. PS: the order of occurrence of the characters must be the same as well.
Such as: "super spider pool"
This case would only be a complete match to appear in front of search results.
6 matches any character
Sometimes the use of instruction are also likely to encounter the situation matches any character, in which case we need to use the asterisk "*." Baidu does not support, but this is generally not need such a complex.
7 query certain document types
If we want the search engines to find a pdf file, then we need to specify the type of search pdf file, you will need to use the command filetype:, but the instructions are often not easy to enter direct pdf looking for. However, in short, has this feature, you can play a game thing. Supported types are:
doc, pdf, ppt, xls, rtf and all, and finally this all on behalf of all file types.
Such as: filetype: pdf seo tutorial
This example is to say on the results page to find the pdf document of seo tutorial.
8 Advanced instructions can be integrated use
In fact, it can be seen in the example above, these instructions are advanced mixed use. You can try to match.
In addition, there are two instructions can be obtained through multiple commands, you can not remember, but it was still to say what, allintitle and allinurl, these instructions are not used repeatedly refers to the intitle and inurl.
Such as: allintitle: super spider pool
This example is equivalent to: intitle: Super intitle: spider pool
