Why Website Industries Uses Subdomains

This article introduces the websites we operate using subdomains.

Why We Use Subdomains

The reasons we operate our websites using subdomains are as follows:

• Search engines such as Google often treat subdomains as separate websites, which makes them easier to optimize for search.
• Organizing content by subdomain makes it easier to manage and maintain each section of the site.
• From a user perspective, separating websites into subdomains makes it easier to access well-organized information.

Each point will be explained in more detail below.

Structuring Websites with Subdomains

Operating websites on subdomains such as gcp.website-industries.com allows us to separate specific content from the main top-level domain and manage each site independently.

Because subdomains are often recognized by search engines such as Google as separate websites from the main domain, it becomes easier to organize information properly and deliver relevant content to users.

Improving Content Management by Dividing Sites into Subdomains

When running websites and publishing information, it is important to consider the management cost of maintaining the site. In addition to the website on the top-level domain, we also operate sites on several subdomains.

By separating content by subdomain, each site can be managed independently. This helps prevent issues such as overly complex category structures, excessive tagging, and a large number of articles or images that can reduce the overall maintainability of the website.

User Readability Is the Most Important Priority

For website operators, the most important factor is how easy the content is for readers to understand.

By separating websites from the top-level domain and organizing content across different subdomains, we can deliver information in a clearer and more structured way for users.

Websites We Operate Using Subdomains

We operate websites on the following subdomains, each dedicated to a specific theme.

Category	Platform / Topic	Subdomain
App Development	App Development	app-dev.website-industries.com
Web Development	WordPress and SEO	wp-seo.website-industries.com
Cloud	Cloud Infrastructure	cloud.website-industries.com
Cloud	Amazon Web Services	aws.website-industries.com
Cloud	Google Cloud Platform infrastructure	gcp.website-industries.com
Linux	Linux	linux.website-industries.com
Linux	Red Hat	rh.website-industries.com
Networking	Cisco	cisco.website-industries.com
Database	Database	db.website-industries.com

What You Can Learn from Website Industries

Website Industries publishes technical and practical information about:

– Cloud infrastructure (AWS, GCP)
– Linux server administration
– Networking technologies such as Cisco
– Database systems including Oracle Database
– Web development and WordPress

The websites we operate originally started with content about website management and operations, and have since expanded to include application development and gadgets used by end users.

This structure reflects a broad range of topics that engineers are often interested in learning, providing a foundation for developing the knowledge and skills associated with full-stack engineering.

The History of Website Industries Site Operations

Website Industries originally started in Japan as a website called “websitefactory.”
Later, we shifted our focus from the .jp domain (websitefactory.jp) to sharing information beyond Japan. At that time, we began using the name Website Industries and adopted the .com domain, which marked the beginning of our current identity.

Originally, websitefactory published content such as:

• Tutorials on customizing websites with WordPress
• Information about WordPress and SEO
• Gadget-related articles, including devices such as the iPhone

Building on this foundation, website-industries.com inherited content from websitefactory.jp and expanded its scope. In addition to the original topics, we began publishing more technical content, including Linux used by server engineers, Cisco technologies, Oracle Database, and cloud computing technologies.

Our shift toward publishing more technical content for server engineers originally began with articles about rental servers used to run WordPress.

In essence, rental hosting services simply allow users to utilize a portion of the resources of on-premises servers.

Becoming interested in this area, the site administrator continued operating the website while also starting to work professionally as a server engineer.

At the time, we were sharing information about hosting services. However, the direction of the content gradually evolved as the site administrator, Yuki Hayakawa, started working professionally as a server engineer while continuing to operate the website.

To illustrate this progression more clearly:

Publishing information about hosting services and server infrastructure (back-end)

The site administrator begins working as a server engineer at a company responsible for building and operating server infrastructure

In addition to the original WordPress, SEO, and gadget content, the site begins publishing more technical content related to servers

The Future Direction of Website Industries

Going forward, our site will continue to publish content from a full-stack engineering perspective, covering a wide range of topics from server infrastructure to applications and gadgets used by end users.

One of the strengths of our media is that it helps readers deepen their technical understanding while providing practical and relevant information across multiple areas of technology.

Conclusion

Website Industries operates multiple websites using subdomains in order to organize information efficiently and deliver content clearly to users.
By separating content into specialized sites, we can improve search engine optimization, maintain each site more easily, and provide readers with well-structured information.

We will continue to deliver optimized content to users by keeping our content specialized across each subdomain.
