1. Site
This is one of the most familiar advanced search commands used to search for all files that a domain name has recorded in the search engine. Major search engines such as baidu, google and yahoo supported the directive。
2, lThink
It is also a commonly used advanced command to search for reverse links to url, and only google supports it, but the search results are inaccurate。
3, lI don't know
The command is also used to search for reverse links to domain names, but only yahoo supports the use of yahoo to check the reverse link data on the website, so it's always used yahoo's lInkdomain: commands to search for reverse links to a website。
4, inurl
The command is supported by baidu and google, both of which are used to search for pages displayed in url。
Instruction format: inurl: hospital network marketing。
Usage techniques: inurl commands an accurate search of personal blog entries, such as: i applied for a user blog called jiangkanek in 100 degrees, so what about our accurate search blog entries? The correct search method is the site:hi. Baidu. Com inurl:jiankanangek command that means hi. Baidu. Com (100 degrees spatial domain name) contains the page of jiankanangek (user name)。
5, allinurl
Similar to inurl, the difference is that the allinurl command can search for multiple keys at the same time word
Form of instruction: allinurl: hospital network camp extension skills
6 and inanchor
Imports a page of the link anchor text containing the search word, which is not supported by baidu。
Command format: inanchor: the results of the hospital network marketing return page do not contain the words "hospital network marketing" in itself, but rather the words "hospital network marketing" appear in the link anchor text of these pages。
Usability techniques: using the directive to find out which websites the competitors are going to publish, it is also a fast-tracking approach to offline resources, unfortunately not supported by baidu。
7, initle
This command returns with the result that the page type contains keywords and that both baidu and google support it。
Instruction format: inittle: hospital network marketing
Usage techniques: for example, if we ask the competition for the key word "hospital network marketing", then using initle commands to query the return result will be your strongest competition。
8. Allintitle
The command means the same thing as initle, and the query page contains keywords, but the only thing that doesn't exist is
Allintitle commands search for multiple keywords at the same time。
Instruction format: initle: hospital network marketing techniques for hospital promotion
9, filetype
This command is supported by baidu and google for searching for specific file formats
Instruction format: filetype: hospital network program doc returns documents containing hospital network program
10.(-) minus sign
Minus marks represent pages that do not contain words behind them. Subtracts need to be preceded by spaces, there is no space behind the subtract, and the instructions are supported by baidu and google immediately following the words that need to be excluded。
For example, the search-engine return results in the inclusion of the word “search”, but not the word “engine”。
11, (“”) double quotation marks
Places the search word in a double quote, representing a complete match to the search, meaning that the page returned with the search result contains all the words that appear in the double quote and must be fully matched, and that command is supported by baidu and google。
For example, searching for encyclopaedia with double quotes on the first page of a hundred degrees allows the results to be searched with the words " encyclopaedia", "double quote" and "search". However, the search of the encyclopedia double-quota search on the first page of the 100-degree page allows only the results of the search with the encyclopedia double-quota search as the key word。
For example, search: "hospital network marketing" returns with a complete match that doesn't pass the word. Page
12,(*) asterisk
An asterisk is a common wildcard that can also be used in a search, and baidu does not support search command *。
For example, search in google: hospital net* marketing, where * stands for any text. The results of the return include not only “hospital network marketing”, but also “hospital network marketing”, “hospital network marketing”。
