What is a Sitemap?

A sitemap is a file that provides humans and search engines with a list of webpages and files on a site. The specific files vary from site to site but usually include images, videos, and PDFs.

Sitemaps can be created for human visitors (HTML sitemaps) or web crawlers and search engines (XML sitemaps). Both sitemaps help humans and search engines understand the relationship between webpages and files on the site.

Types of Sitemaps

There are two types of sitemaps, namely: 

  • HTMLサイトマップ
  • XML sitemap

1 HTML Sitemaps

The HTML sitemap provides human visitors with links to the content on a site. It is usually a regular webpage formatted into a sitemap. 

Sample of an HTML sitemap

The content included in an HTML sitemap varies from site to site. However, they typically include the clickable title of the webpages they link to. Some may split the content by category and include their last modified time. 

While created for human visitors, search engines may use the HTML sitemap to understand the hierarchy of the content published on the site.

2 XML Sitemaps

XML sitemaps provide search engines with links to a site’s content. They usually include the content’s URL, image count, and last modified time. 

Sample of the XML sitemap

XML sitemaps are created using a .xml file and can typically be accessed by adding sitemap.xml また sitemap_index.xml after your domain name. For example, https://yourdomain.com/sitemap.xml また https://yourdomain.com/sitemap_index.xml.

Although created for search engines, human visitors can access the XML sitemap. Some bloggers even use the XML sitemap for competitor research. This allows them to discover their competitor’s latest posts and gain insights into their content strategy.

Importance of Sitemaps

Sitemaps help visitors and search engines to discover the content on your site. This ensures that search engines can always identify and crawl your content. This makes them helpful for discovering 孤立したページ, which are webpages that are not linked to other content on your site. 

Sitemaps are also helpful for visitors looking to find or discover content on your site. Instead of relying on the search bar or filters, they can visit your HTML sitemap to discover the content they are interested in.
