Search engine commands that seoer has to know

In addition to common keywords, a search engine can also use some special advanced search engine commands. Ordinary users generally do not use these search engine commands, but from the perspective of SEO practitioners, these search engine commands are useful for understanding the SEO optimization effects of your website, researching competitors, and searching for resources to optimize external links.

1. Site
Usage -- site: domain name.
One of the most well-known search engine commands by webmasters and seoer is used to search all the content and pages indexed by search engines under a domain name. This search engine Command is often used to query the number of records recorded by a website in a certain search engine. However, the site command is not very accurate, and the query results often fluctuate greatly and can only be used as a reference.
In addition, some time ago, Baidu had made it clear that the site command was unreliable and promoted its product "Baidu Statistics". This is a digress. In addition, the site can be used to query subdomain names.

2. Link
Usage -- Link: URL.
It is also a common search engine Command Used to query reverse links of a specified URL, including internal and external links. However, the link command is still unreliable, and the results returned by the query are basically random.
The results returned by Google's link command are often part of the random content in the Google index library. Although Baidu now supports this command, the returned results are incredibly painful. For example, in Baidu link: www.yushenblog.com, www. linkfromblog will appear in the result. COM and autobloglink. Com. Therefore, using the link command to query external links is almost useless.

3. Domain
Usage -- domain: URL
Search engine commands for querying the target URL anti-chain. The number of Baidu anti-chain commands in most webmaster tools included in the online query is basically based on this search engine Command. Strictly speaking, this
The role of the domain command is to query the page with the target URL, that is, the URL form of the external chain, of course, does not include the link anchor text. So, you know. In addition, Google does not support this metric.
.

4. intitle
Usage -- intitle: keyword
I personally like a search engine Command.Target keywordThe degree of competition has a certain effect. The intitle command is used to query webpages with the target keyword displayed in the title tag. You can get a rough idea of the page where the target keyword appears, the competition degree of the keyword is roughly grasped from the aspect.

5. inurl
Usage -- inurl: keyword (generally in English)
Search for the URL with the target keyword. Generally, the URL is composed of English letters. Therefore, an inurl keyword is usually an English keyword.

6. Double quotation marks
Usage-"keyword (or URL )"
Many websites and search engine commands that the seoer practitioners do not know or do not pay attention to are used to query the webpage content that exactly matches the target keyword. When querying a keyword, Google will display a page with the keyword "exact match (including order)", which is unreliable in Baidu.
In addition, when you use this search engine Command to query a URL, the effect is similar to that of domain commands.

7. allintitle
Usage -- allintitle: keyword a keyword B
This search engine Command indicates the pages on which the title tag of the search return page contains the preceding target keywords, which is equivalent to intitle: keyword A intitle: keyword B. Well understood.

8. allinurl
Usage -- allinurl: keyword a keyword B
For this search engine Command, see inurl command and allintitle command.

9. wildcard characters
Usage-off * Words
The wildcard asterisk "*" can represent any word. It is also easy to understand and will not be explained much.

The search engine commands described above are mainly for Baidu and Gu Ge. Of course, they do not contain all the search engine commands. Later, I will introduce several little-known advanced search engine commands.
Although many search engine commands are named "unreliable", most search engine commands are of reference value. You can practice and judge on your own.
