seo query command_html/css_WEB-ITnose

The following contents are all from the Internet, just slightly organized

The ones that I feel are easier to use are 1, 5, 6, 11, 12, 13

1. site command:

Query the inclusion status of a specific website. For example, the query format for 6676 mini-games is: site:www.6676.com

2. link: or domain: Command:

Query the outside of a website Links, external links are an important factor in obtaining ranking and weight, especially for Google. Similar to the site command, the domain domain name can also know the health status of the website.
Except for Baidu, the query format for other major search engines is: link:your domain name (the format for querying this site on Baidu is: domain:www.dacheng86.com). The Yahoo webmaster tool is the most accurate for querying external links. .

3. info command:

Query the included information of the specified website, recent cache, similar web pages, site links, internal links of the website, web pages containing domain names, etc. The format is: info:your domain name

4. cache command:

To get the last time a search engine included your website, enter a page of the site, You can find the date and version of Spider's most recent collection. For example: cache: http://www.6676.com　

5. allinurl: or inurl: command

Retrieve the specific content contained in the URL title of the web page. For example: inurl:edu.cn exchange links, you can find websites that are willing to exchange school links.

6. allintitle: or intitle: command

7. allinanchor: or inanchor: command

8. allintext: Command

Display all web pages containing these words in the document. In SEO, it is used to discover relevant sites and potential links, and is often used to query competitors.

9. define: command

This advanced feature is rarely used by SEO, but it is still very valuable. It is equivalent to a dictionary. Searching for specified words is equivalent to Baidu Encyclopedia. In Google, you will find that it is more accurate than Baidu!

10. related: Command

Query web pages that are particularly related to a certain web page. The format is: related:your domain name. If you search for a specific phrase in Google, you will find that it is more accurate than Baidu.

11. filetype command:

It is not an exaggeration to say that filetype is a powerful tool. You can get whatever you want on the Internet. What it does: Used to search for specific file formats. If you want to get PDF files about "A Brief History of Information", you can search like this: "filetype:pdf A Brief History of Information". The returned results are all PDF files that contain the keyword "A Brief History of Information". As for other formats, I won’t go into detail. They generally include pdf, doc, xls, ppt, rtf, etc.

12. Double quotation marks:

Put the search term in double quotation marks to represent a complete match search, which means that the page returned by the search results contains double quotation marks. All the words, even the order, must match exactly. Both Baidu and Google support this directive.

13. Minus sign:

The minus sign means searching for pages that do not contain the word after the minus sign. When using this command, there must be a space after the minus sign. There must be no space after the minus sign, followed by the word that needs to be eliminated. Both Google and Baidu support this directive. For example: search engine returns the result that contains the word "search" but does not contain the word "engine"

14. Star:

Star * is a commonly used wildcard character that can also be used in searches. Baidu does not support the * search command. For example, searching in Google: Search * engine where the * sign represents any text. The returned results include not only "search engine", but also "search engine", "search giant" and other contents.

15. Book title number:

The book title number "" is quite special and is a unique Chinese symbol. Search engines such as Yahoo and Bing do not support this advanced search command. Search engines such as Baidu, which understands Chinese best, Google, which understands Chinese better, Sosou, Sogou, which understands Chinese slightly, can all recognize book titles.
