互联网上 95% 的信息都可以通过搜索找到解决方案，有效的利用搜索引擎的查询指令可以极大的提高工作的效率，比如竞争对手分析，精确的资料查询。
一、谷歌搜索指令
1. 双引号 “”
把搜索词放在双引号中，代表完全匹配搜索，也就是说搜索结果返回的页面包含双引号中出现的所有的词，连顺序也必须完全匹配。
2. 减号 –
减号代表搜索不包含减号后面的词，有时候不想看搜索结果出来的一些关键词，那么就可以利用减号的指令来排除。
注意：使用这个指令时减号前面必须是空格，减号后面没有空格，紧跟着需要排除的词。
3. 星号 *
星号是常用的通配符，也可以用在搜索中代表任何文字。比如，你只记得 “亡羊补牢” 的前两个字，那么可以输入 “亡羊**” 搜索。
4. inurl:
inurl: 指令用于搜索查询词出现在 url 中的页面，比如搜索 “inurl:hair extension” 的返回结果的网址 url 中都包含“hair extension”。由于关键词出现在 url 中对排名有一定影响，使用 inurl: 搜索可以更准确地找到竞争对手。
allinurl: 指令的作用与 allintitle: 类似。
5. intext:
intext: 指令用于搜索包含特定关键词的网页，不理会网址 url 和文章标题。例如 “intext:exploits” 将只返回包含指定关键字 “exploits” 的网页结果。
6. intitle:
intitle: 指令用于搜索页面 title 中包含关键词的页面，可以找到更准确的竞争页面。
当想在标题里面搜索超过2个词的时候，可以使用 “allintitle:”，当然也可以使用 “intitle” 来代替搜索，“intitle: login intitle: password” 和 “allintitle: login password” 的搜索结果是一样的。
7. site:
site: 指令用来搜索某个域名下的所有文件，但是现在这个指令不太准确，只能用来作参考。
8. filetype:
filetype: 指令用来搜索特定格式的文件。例如 “filetype:doc site:gov confidential” 将搜索所有 .gov 的政府网站上的 .doc 文件和含有 confidential 关键字的页面。
9. link:
列出所有包含特定链接的页面，例如 “link:www.securityfocus.com” 将列出所有包含指向 “www.securityfocus.com” 主页的页面。
10. related:
返回结果是与某网站有关联的页面，例如 “link:www.securityfocus.com” 将列出所有包含指向Securityfocus 主页的页面。
二、使用案例
OK，其实谷歌搜索命令很简单，重要的是要学会运用、去发掘可以利用的信息、去解决问题，这才是最重要的。
1. 找行业资源
比如我们有时想要找行业的测评师，或者是寻找行业的素材内容，如何下手呢？

2. 找可以提交网站的入口资源
SEO 中最核心的内容就两点：优秀的内容与相关性强的外链。其实找可以提交网站的入口资源就相当于提交外链申请，高质量且一定数量的外链会对网站权重的提升很有帮助。

"deals for" + "keyword" + intitle:submit / add
"coupons for" + "Keyword " + intitle:submit / add
keyword + sweeps* + intitle:submit
keyword + giveaways + intitle:submit那么直接通过关键词加上相关词条进行搜索就能找到不少可以做外链的网站。
3. 找非盈利机构
搜索引擎喜欢非营利性的机构和组织，搜索引擎认为如果这些组织能给你做链接，那么你的网站一定程度上是代表可信的，所以类似 org，edu 这种域名的是很受欢迎的。
In US (www.google.com)
Keyword + site:.org
In UK (www.google.co.uk)
Keyword + site:.org
Keyword + site:.org.uk
In India (www.google.co.in)
Keyword + site:.org
Keyword + site:.org.in
In Canada (www.google.ca)
Keyword + site:.org
In Australia (www.google.com.au)
Keyword + site:.org
Keyword + site:.org.au4. 找工具插件
比如我要查看行业推广工具，那么是不是要找到他们。
industryName + intitle:tools
industryName + intitle:badges
industryName + intitle:widgets
industryName + intitle:infographics
industryName + inurl:tools
industryName + inurl:badges
industryName + inurl:widgets
industryName + inurl:infographics
industryName + top/recommended/useful/favorite/amazing/awesome tools
industryName + top/recommended/useful/favorite/amazing/awesome badges
industryName + top/recommended/useful/favorite/amazing/awesome widgets
industryName + top/recommended/useful/favorite/amazing/awesome infographics
5. 找推广资源
比如我现在想为我的亚马逊产品找站外推广资源，想找那些可以为我产品做 Review 的博客资源。
ProductName + review + site:wordpress.com
ProductName + ratings + site:wordpress.com
ProductName + comparison + site:wordpress.com
ProductName + price comparison + site:wordpress.com
