Understanding WordPress Multisite: Is It Right for You?

Last modified: September 11, 2025

What is WordPress Multisite?

WordPress Multisite is a powerful feature built into WordPress core that allows you to create and manage a network of multiple websites from a single WordPress installation. Think of it as having one central dashboard to oversee several distinct sites.

Instead of installing WordPress separately for each website you want to run, Multisite lets you use one installation to power them all. These sites share the same core WordPress files, themes, and plugins. However, each site in the network has its own separate media uploads directory and distinct tables in the database to keep its content (posts, pages, settings) separate.

A special user role, the “Super Admin,” has access to the entire network and manages network-wide settings, including theme and plugin installations. Individual site administrators manage the content and settings for their specific sites but typically cannot install new themes or plugins themselves.

How Sites Can Be Structured

When you set up Multisite, you’ll choose how the URLs for the sites in your network are structured. (You can find more details on each structure in our guide).

On Pressable, all accounts support the subdirectory structure. Using subdomains or custom domain mapping requires a plan that supports 5 sites or more.

Subdirectories: Sites live in folders under your main domain (e.g., yourdomain.com/site1, yourdomain.com/site2). Note: This option is generally available only if your main WordPress site is brand new. (Available on all Pressable plans).
Subdomains: Sites use unique subdomains of your main domain (e.g., site1.yourdomain.com, site2.yourdomain.com). (Requires a 5-site plan or higher on Pressable).
Domain Mapping: You can map unique custom domains to individual sites within the network, so they appear as completely separate websites (e.g., customdomain1.com, anotherdomain.net). (Requires a 5-site plan or higher on Pressable).

Is Multisite Right for Your Situation? Quick Decision Points

Multisite can be a fantastic solution, but it’s not always the best fit. Consider these points:

Multisite might be a good fit if:

You need to manage a group of closely related websites (e.g., departments of a university, branches of a business, a network of blogs on similar topics).
You want consistent branding and functionality across all sites using shared themes and plugins.
Centralized management is a priority – updating themes, plugins, and users across all sites from one place.
You anticipate adding more similar sites in the future.

**Multisite might not be a good fit if:**

You are managing websites for different clients who need complete independence.
The sites require vastly different themes, plugins, or functionality.
Each site owner needs the ability to install their own themes and plugins.
Each site needs its own separate hosting environment or IP address.
You prefer simpler site management or have limited technical resources for troubleshooting potential network-wide issues.

Digging Deeper: Pros, Cons, and Risks

Let’s explore the advantages and potential drawbacks in more detail.

Advantages of Using Multisite:

Centralized Management: The biggest win! Update themes and plugins once for the entire network. Manage users across all sites from a single dashboard. This saves significant time and effort.
Consistency & Efficiency: Easily enforce consistent branding and features by activating themes and plugins network-wide. Avoid installing the same plugin multiple times on separate sites.
Scalability: Adding a new site to the network is generally much faster than setting up a completely new WordPress installation.
Streamlined User Management: Users can potentially share one login across multiple sites in the network, simplifying their experience.

Disadvantages and Risks of Using Multisite:

Single Point of Failure: This is a critical consideration. If your main WordPress installation experiences technical issues or security breaches, the entire network of sites is affected.
Shared Hosting Resources: The entire Multisite network is a single WordPress instance under the hood, meaning it runs within a single hosting container. This means all sites in the network share the same resources (like PHP workers, CPU, RAM). A busy or resource-intensive site can potentially impact the performance of all other sites in the network, as they don’t have the isolated resources of separate single-site instances.
Technical Complexity: Setting up and managing a Multisite network requires more technical understanding than a standard single site. Configuration, domain mapping, and troubleshooting can be more complex. While Pressable provides robust hosting infrastructure, troubleshooting issues specific to the multisite configuration itself often requires specialized knowledge and may fall outside our standard scope of support (see our Support Policy).
Plugin and Theme Limitations: Not all WordPress plugins and themes are designed to work smoothly with Multisite. Compatibility issues can arise. Furthermore, individual site administrators usually cannot install or update themes/plugins; only the Super Admin can.
Database & Migration Challenges: All sites share a single database (though with separate tables). This makes backing up or migrating an individual site out of the network significantly more complex than with a standard WordPress site. Extracting a single site requires careful database manipulation. While Pressable offers tools for accessing backups and taking manual backups of the entire installation, isolating a single sub-site is a more involved process that falls outside our support scope.
Hosting Requirements: While the network shares one plan, Multisite networks generally require more robust overall hosting resources (CPU, RAM, database power) than a single site, especially as the network grows or individual sites become busy. You’ll need to ensure your plan can handle the combined load.
Customization Limits: While sites have separate content, deep customization on individual sites can sometimes be constrained by the shared theme/plugin environment managed at the network level.
SEO Considerations: Your choice of URL structure (subdomain vs. subdirectory vs. mapped domain) can have different implications for your SEO strategy. It’s wise to research this or consult an SEO expert based on your network’s goals.

Using WordPress Multisite on Pressable

Pressable fully supports WordPress Multisite! You can set up your network using subdirectories, subdomains, or custom domain mapping, keeping in mind the plan requirements mentioned earlier.

Our managed WordPress hosting platform provides the performance, security, and reliable infrastructure necessary to run a demanding Multisite network effectively. While managing the specifics of your Multisite configuration falls to you (the Super Admin), our platform ensures the underlying server environment is optimized for WordPress.

If you have questions about setting up domain mapping (on eligible plans), need help migrating an existing Multisite network to Pressable, or have questions about whether your current plan has sufficient resources for your network, please don’t hesitate to contact our support team.

Making the Right Choice

Choosing WordPress Multisite depends heavily on:

The relationship between your sites: Are they closely related, or completely independent?
Your technical comfort level: Are you prepared for the added complexity?
Your long-term goals: Do you need centralized control and easy scaling for similar sites?

If Multisite feels too complex or doesn’t fit your needs (especially if managing sites for separate clients), consider managing individual WordPress sites using a dedicated management tool.

Pressable partners with MainWP, which allows you to manage updates, backups, and more for multiple separate WordPress sites from a single dashboard. You can learn more about Pressable’s partnership with MainWP here.

Ultimately, understanding the trade-offs between centralized control and potential complexity is key to deciding if WordPress Multisite is the right path for your project.
