To learn SEO, then we start from the most basic search engine grammar, following the collation of Baidu, Yahoo, Google three search engines for advanced syntax and application.

Baidu Search Advanced Syntax

1, limit the search scope in the title of the page--intitle

The page title is usually a kapitalmakes of the content of the Web page. Limiting the scope of the query content to the title of the page can sometimes achieve good results. The use of the method is to put the query content, particularly critical parts, with "intitle:" Collar up. such as: Beautiful picture intitle:meinv55

2, limit the search scope to the specific site--site

Sometimes, if you know that there is something you need to find in a certain site, you can limit your search to this site and improve query efficiency. The way to use, is in the query after the content, plus "site: site domain name."

For example, beauty picture site:www.meinv55.com

3, limit the search scope in the URL link--inurl

Some of the information in the URL of a Web page often has a valuable meaning. As a result, you can get a good result if you qualify the URL for the search results. The way to implement this is to use "inurl:" followed by a keyword that needs to appear in the URL. such as: Beautiful picture inurl:meinv55

4, exact match--double quotes and title number

If the input query word is very long, Baidu after analysis, given the search results of the query words, may be split. If you are not satisfied with this situation, you can try to let Baidu do not split query words. Add double quotes to query words to achieve this effect. such as: "Fred SEO Service"

5, require the search results do not contain specific query words

If you find that some type of Web page you don't want to see in your search results, and that these pages contain specific keywords, then use the minus syntax to remove all the pages that contain specific keywords. such as: SEO Services-Fred

1, "site" means that the search results are limited to a specific site or site channels, such as "www.meinv55.com", "edu.sina.com.cn", or a domain name, such as "com.cn", "com" and so on. If you want to exclude a site or domain name within the scope of the page, just use the "-site/domain name." such as: SEO site:www.meinv55.com

2. "Link" syntax returns all pages linked to a URL address.

Example: Search all pages with links to the "www.guanyufanyi.com" link to the translation company. Search: "Link:www.guanyufanyi.com"

3. The "inurl" syntax returns a page link that contains the first keyword, followed by a keyword that appears in a link or in a Web page document. There are many web sites that have the same attributes of a resource name in the directory name or Web page name, such as "MP3", "gallary", and so on, you can use the Inurl syntax to find these related resource links, and then use the second keyword to determine whether there is a specific data. The biggest difference between the Inurl grammar and the basic search syntax is that the former usually provides very precise information about the topic. such as: Search: "Inurl:pdf seo"

4, "Allinurl" syntax returned by the link to the Web page contains all query keywords. The object of this query is focused only on the link string of the page.

Example: Find a company web site that may have PHF security vulnerabilities. Usually the CGI directory of these sites contains PHF script (this script is unsafe), in the link is "domain/CGI-BIN/PHF." Syntax: "Allinurl:" CGI "PHF +com"

Related is used to search for similar web pages in terms of structure content. For example: Search all pages similar to the Chinese Sina homepage (such as NetEase home, Sohu Home, China Net homepage, etc.), "related:www.sina.com.cn/index.shtml".

The cache is used to search for a cached page on a Google server, which, like a "snapshot of a page", is typically used to find some dead-link pages that have been deleted, equivalent to using the "snapshot" feature in the normal search results page.

Info is used to display a series of searches related to a link, providing cache, link, related, and the functionality of a Web page that fully contains the link.

Yahoo Advanced Search Syntax

"Title:" is used to search for headings. For example: Search title: Jacky Cheung, search engine will return all the pages that contain "Jacky Cheung" in the title. Because the title of a Web page usually accurately describes the content of a Web page, using "title:" For searching may be more accurate.

Link: is used to find all pages linked to a Web site. For example: Search for link:http://www.yahoo.com.cn/, get all the pages linked to "www.yahoo.com.cn"; search Yao Ming link:http://www.yahoo.com.cn/or Link:http ://www.yahoo.com.cn/Yao will get all the pages linked to "www.yahoo.com.cn", including the word "Yao Ming". Please note: "http://" cannot be missing during search.

"Site:" or "domain:" is used to qualify the source of search results. For example: Search

Yao Ming site:yahoo.com.cn or Yao Ming domain:yahoo.com.cn or the "Yao" and site, domain statement swap position (note the middle use space separated), search engine will return in the domain name "www.yahoo.com.cn" And all the pages that contain the word "Yao Ming" in their subdomains.

The usage of "hostname:" is the same as "site:", "Domain:" except that when using "hostname:" Only the page under the current domain name is returned, not the page in its subdomain.

URL: For exact search of URLs. For example: Search url:http://cn.yahoo.com, search engine will only return a result-Yahoo China.
