seo tutorial, what are the advanced search engine commands commonly used in SEO?

Some commonly used advanced search engine commands include the following:

1. Site

This is the most common advanced search command, which is used to query the inclusion status of a website, and this command is universal in all search engines. Usage: site:www.XXXX.com

2.Domain

Check the backlink status of the website. This command is only applicable to Baidu, and the results are not so satisfactory. Because the result he found is not a backlink, the effect is not as good as double quotes (" "). Domain usage: domain: www.XXXX.com

3. Inurl/allinurl

inurl queries pages that contain keywords in the URL. This command is often used. For example, we can search blogs in batches: inurl:blog. Allinurl refers to the page whose URL completely contains keywords, which is more accurate than inurl. These two commands work with most search engines. Usage: inurl:seo

4. intitle/allintitle

Intitle searches for pages that contain keywords in the title, while allintitle searches for pages that completely contain keywords in the title. Baidu does not support these two commands very well, but Google supports them very well. Usage: intitle:seo training.

5. Double quotes ""

Search for pages that exactly match the content in quotation marks. This command is an advanced command used by most search engines. Its usage is: "seo is something"

6.Filetype

Query files of the specified format. This command is very useful for people who are searching for information. Most search engines support the filetype command, usage: filetype:doc

7. Wildcard *

You can use this command when you can't remember the full name of the search term, such as "search engine *", and many results related to the search engine will appear.

8. Minus sign —

Search for pages that do not contain the content after the minus sign. Baidu does not support this command very well, but Google fully supports it. Usage: keyword 1 - keyword 2
