What exactly is a sitemap?
Search engines such as Google do not cover information from all websites in the world.
In fact, a site map has the role of conveying to search engines the information and content of your site, such as, “This is the address of my site!” “There are XX pages!”

How to set up Search Console

1. Access “Search Console”
If you have a Google account, just log in.

2. Register URL
After logging in to “Search Console”, a form to enter the URL will be displayed, so enter the site address starting with http or https and press the confirm button.


3. Verify site ownership
Next, we check to see if the URL applicant is the site owner.
How to check these
A. How to embed the specified meta tag into the page
B. How to transfer the specified page to the server using FTP etc.
C. How to check using Google Analytics analysis tag

There are many ways to do this, but I think the quickest way is to use the Analytics tag, which every webmaster must have set up.
If the Google accounts used for Search Console and Analytics are the same, ownership verification can be completed in an instant.
4. Submit your sitemap
Click “Sitemap” from the menu on the left side to display the sitemap registration page.

Next, write the address of the site’s xml sitemap and send it.

Sitemap address of each CMS and how to create a sitemap
In the previous section, we explained how to register a sitemap, but if you’re wondering, “Where can I find a sitemap in the first place?”
https://domain/sitemap.xml
If you add “/sitemap.xml” to the end of the domain and you see a list of data enclosed in <url> like the one below, it is a “sitemap”.
Although it is often confused, it is different from a sitemap created with an HTML page, and is simply a data file that contains the URLs of existing pages, update frequency, update date and time, etc.

If the sitemap of your site is not displayed at https://domain/sitemap.xml, create the data manually using Notepad and save it on the server, or search for “sitemap generation tool” etc. There is also a way to automatically generate a sitemap using the sitemap generation tool displayed in .
If you are using WordPress, there is no sitemap generation function by default, but if you use an SEO plugin (such as the standard All in one SEO Pack), a sitemap will be automatically generated.

summary
Sitemaps registered with SearchConsole etc. are different from sitemaps created with HTML pages, and are simply data files containing the URLs of existing pages, update frequency, update date and time, etc.
If you have not registered these, there may be pages where Google does not recognize your site’s information and content, so be sure to set them up once you publish your site.
