    What are Subdomains?

    Subdomains are extensions of the main domain. They act as separate branches, allowing businesses to separate content, functions, or products/services without purchasing a new domain.

    For example: If your main domain is doanhnghiep.com, you can create subdomains like:

    • blog.doanhnghiep.com
    • support.doanhnghiep.com
    • shop.doanhnghiep.com

    The Difference Between a Main Domain and a Subdomain

    The main domain represents the entire website, while the subdomain is an extension, helping to divide functions or categories. Each subdomain can be configured as a separate website with different content, design, and management systems.

    Benefits of Using Subdomains for Business

    Organize Specialized and Effective Content

    Subdomains help separate content according to specific customer groups or objectives. For example, you can use academy.tenmien.com to provide training materials, while customer.tenmien.com is used for customer service.

    Optimize Website Performance

    Dividing traffic between subdomains helps reduce the load on the main domain, improve page loading speed, minimize response time, and improve user experience.

    Support International or Multilingual Development

    Subdomains are very effective when deploying international campaigns. For example:

    vn.tenmien.com for the Vietnamese market

    en.tenmien.com for the international market

    This allows you to customize content, interface, and user experience for each separate market.

    Increase Flexibility in Management and Development

    Each subdomain can use a different platform, separate development team, and independent content. This is very convenient for large businesses or multi-industry organizations.

    Do Subdomains Affect SEO?

    There are many opinions surrounding how subdomains affect SEO. According to Google, both subdomains and subfolders are evaluated as separate entities. However, if optimized correctly, subdomains can still rank well in search results.

    When Should You Use a Subdomain Instead of a Subfolder?

    • When the content needs to be completely separated technically or functionally
    • When you want to create a sub-brand or independent category
    • When you need to build a landing page or microsite for a specific marketing campaign

    Things to Note When Optimizing SEO for Subdomains

    • Ensure quality content that is not duplicated with the main domain
    • Build backlinks for each subdomain as an independent site
    • Submit a separate sitemap for each subdomain to Google Search Console
    • Configure HTTPS for each subdomain to ensure security

    How to Create and Manage Subdomains for Business

    Create Subdomains Through a Hosting Provider

    Most hosting providers support creating subdomains very easily. Just log in to Cpanel or the administration page, go to the “Subdomain” section, enter the name and point to the corresponding subfolder.

    Create Subdomains Using DNS

    You can create subdomains via DNS by adding an A or CNAME record pointing to the corresponding IP or address.

    Manage Subdomains Effectively with a CMS System

    CMS systems like WordPress, Drupal, or Joomla all support multi-site or installation on separate subdomains. This makes it easy to update content, maintain, and develop subdomains as an independent website.

    Common Applications of Subdomains in Business

    Blog Page, Sharing Knowledge

    Use blog.tenmien.com to build an in-depth content ecosystem, increasing organic traffic from Google.

    Customer Service Portal

    support.tenmien.com or help.tenmien.com is an ideal place for businesses to provide guidance, answers, and customer care.

    Recruitment or Internal Website

    careers.tenmien.com helps businesses attract professional personnel. internal.tenmien.com can serve as an internal portal for employees.

    Landing Page or Microsite per Campaign

    Subdomains like sale.tenmien.com or event.tenmien.com serve specifically for each marketing campaign, helping to increase measurement efficiency and traffic routing.

    Strategies for Leveraging Subdomains to Develop a Brand

    Positioning a Sub-Brand

    Subdomains can become a small brand within a larger brand. For example, academy.tenmien.com can become a training center widely known in the industry.

    Building a Specialized Community

    Subdomains like forum.tenmien.com are where you can build a loyal user community, contributing to increasing brand value.

    Expanding the Service Ecosystem

    Businesses can create multiple subdomains such as:

    booking.tenmien.com for scheduling

    shop.tenmien.com for online sales

    partner.tenmien.com for partners

    Each subdomain acts as a separate branch, helping to expand the brand's influence.

    Common Mistakes When Using Subdomains

    Not Optimizing SEO for Each Subdomain

    Many businesses think that subdomains inherit all the power from the main domain, but in reality, Google evaluates them as separate entities.

    Illogical URL Structure

    Subdomains need to be short, easy to remember, and clearly express the purpose. Avoid using long, confusing, or irrelevant phrases.

    Not Using SSL or Poor Security

    Each subdomain needs its own security certificate to ensure user safety and maintain good rankings on Google.

    Subdomains and Marketing Strategy

    Subdomains for Email Marketing

    Creating separate subdomains like email.tenmien.com helps to streamline mail sending, avoid being marked as spam, and easily track effectiveness.

    Advertising and Tracking Integration

    Subdomains can be used to A/B test ads, analyze user behavior, or deploy more effective tracking tools.

    Subdomains in Remarketing Campaigns

    Through subdomains, you can create exclusive experiences for potential customer groups, personalize content, or offer exclusive offers.
