Search engine is an indispensable part of our life, we use search engine almost every day, search engine provides us with some special instructions to facilitate search, called "search engine advanced search instruction", referred to as search engine instruction. Engaged in the SEO service industry, we must understand the common syntax of search engines. Proper use can help us find the resources we want more quickly and accurately.

Baidu is the largest Chinese search engine in China, and it is also the one with the most open search engine instructions. So here only list Baidu search engine instructions, other search engines can only use site command for the time being.

1. Double quotation marks

Enclosing the search term in double quotation marks means that the search exactly matches, that is, the page returned by the search results contains the words that appear in double quotation marks and must be matched continuously.

For example: Baidu home search Baidu encyclopedia with double quotation marks search can be found respectively with "Baidu encyclopedia", "double quotation marks" and "search" as the keyword results. But Baidu home page search "Baidu encyclopedia with double quotation marks search" can only search "Baidu encyclopedia with double quotation marks search" as the keyword results.

two。 Minus sign (-)

The minus sign (-) represents a page that does not contain the word after the minus sign. When using this instruction, the minus sign must be preceded by a space, followed by no space, followed by the word to be excluded.

For example: Baidu home search Baidu encyclopedia with double quotation marks search can be found respectively with "Baidu encyclopedia", "double quotation marks" and "search" as the keyword results. But search Baidu encyclopedia in Baidu home page with double quotation marks-search can only search results with "Baidu encyclopedia" and "double quotation marks" as keywords.

3. Inurl: the directive is used to search for pages where query words appear in url.

4. Intitle: the directive returns the page that contains keywords in the page title.

5. Allintitle: the search returns files with multiple sets of keywords in the page title.

6. Allinurl: the function is similar to allintitle.

7. Filetype: used to search for specific file formats. For example, a search for "filetype:pdf seo" returns a pdf file that contains seo.

8. Site: the most familiar search instruction for seo personnel, which is used to search all indexed pages or resources under a domain name.

How to use search engine instructions to find resources?

I. the use of intitle instructions

To inquire about the inclusion of our title. For example, we look up a title that contains "excavator". Just enter intitle: excavator

We can see all the websites where the title and description contain the keyword "excavator". So what's the difference between it and direct search?

We can see. There's a big difference. The result with the command is very accurate, showing us all the title and description including "excavator". And directly searched out. It includes Baidu encyclopedia and Baidu pictures. Which one you like to use depends on your personal needs. But you should know that this instruction is to query the information that contains the title.

Second: the use of inurl instructions

Is what the query path contains. This query method is very easy to use. For example, I want to check all the websites that contain BBS forums. Inurl:bbs

In this way, we can find out all the websites that contain BBS forums.

Conclusion: these are the four instructions that I think are the most commonly used. As long as you use it. You don't have to worry about not finding the outer chain platform anymore.

For example, I do wholesale flowers. I'm going to post on the forum. But I don't know where to find these forums. It's simple.

Intitile: flower wholesale inurl:bbs

I work as a car GPS. To find a B2B platform. Intitle: on-board GPS inurl:b2b

I'm a wedding photographer. Want to find the forum to send out the chain. Intitile: wedding photography inurl:bbs

I will not enumerate the above. I hope you can use it flexibly.
