Does your organization have multiple umbrellas that serve different purposes or audiences? If you answered yes, then you might be like many of our clients who have wondered whether a WordPress multisite would help them better manage their presence online. In this blog post we will share the benefits and challenges of building a WordPress Multisite. We will also share best practices, common use cases and alternatives to consider.

What is a WordPress Multisite?

WordPress multisite is a feature that allows you to run multiple websites from a single WordPress installation. It's designed for organizations that manage several sites with shared resources and centralized control. Whether you're an educational institution, a franchise business, or a large corporation with multiple brands, a multisite could be helpful.

Exploring The Benefits of a Multisite

Implementing a WordPress multisite architecture has several advantages, including streamlining your web management process and getting more bang for your website investment buck.

  1. Centralized management of site and users

With a multisite, you can manage all your sites from a single dashboard. This centralization saves time and reduces the complexity of managing multiple separate WordPress installations. A single login gives you access to everything. Administrators can also oversee user accounts, content, and settings for all sites in one place.They can also implement network-wide user roles and permissions. This is particularly beneficial for large organizations where users may need access to multiple sites with varying levels of permissions.

  1. Shared resources and themes

You can also use the same themes and plugins across all sites. This feature not only ensures consistency of functionality but also simplifies the process of implementing new features or design changes across your network. It's particularly useful for organizations wanting to maintain a cohesive brand identity across multiple sites.

  1. Simplified updates and maintenance

Instead of the cost and time for updating each website individually, a multisite makes it possible for you to update WordPress themes and plugins simultaneously for all sites. This can reduce the time and effort required for maintenance, ensuring all your sites are up-to-date and secure with less effort.

  1. Cost-effective for multiple sites

This architecture can help you save on hosting and licensing costs. Instead of paying for separate hosting and plugin licenses for each site, you can often use a single hosting plan and set of licenses for your entire network, reducing costs.

  1. Consistent branding across sites

Multisites also enable you to maintain a unified look and feel across your network more efficiently. This is important for organizations with multiple departments, locations, or brands that need to present a cohesive image online. multisites can make implementing and managing brand guidelines easier across all your web properties.

  1. Scalability

Whether you're expanding to new locations, launching new products, or creating microsites for campaigns, multisite allows you to quickly deploy new sites without starting from scratch each time.

  1. Proven history

Multisite has been a feature of WordPress since 2010. It has been battle tested for some of the highest traffic websites in the world. In fact, wordpress.com, which has over 810 million individual sites, is a Multisite.

Potential Challenges

  1. Initial setup is more complicated than for a single WordPress site

Switching a WordPress site from being a single site to a multisite is a simple change in the settings. The complexity arises out of what happens next: connecting your different site to individual domains or sub-domains, and the planning necessary for using software that works across all of the sites. This initial setup can be a hurdle for organizations without technical expertise or experience with Multisite.

  1. Potential plugin compatibility limits

Multisites work best when the theme and functionality are similar across all sites. If you have multiple themes and unrelated sites they may not function correctly or conflict with network-wide settings. This limitation can restrict the functionality available to individual sites within the network. Administrators must carefully vet and test plugins before implementing them across the multisite network.

  1. Potential performance issues

WordPress Multisite networks can face performance challenges as they grow. Large networks strain server resources, while poorly optimized themes or plugins can slow down the entire system. Shared database tables often lead to slower query times as the network expands. However, proper setup and management can mitigate these issues. Implementing caching solutions, optimizing database queries, and carefully selecting lightweight themes and plugins can significantly improve network performance. Regular monitoring and maintenance help ensure smooth operations even as the network grows.

Common Use Cases for WordPress Multisite

Educational Institutions

Educational institutions often use multisite to create separate websites for individual schools, departments, or programs. This allows for customized content while maintaining a unified brand across the institution.

Franchise Businesses

Franchises can utilize a multisite to establish individual sites for each location. This enables local customization of content and offerings while preserving overall brand consistency.

Multi-Language Websites

Organizations targeting global audiences sometimes leverage multisite structures to build multi-language websites. This approach allows for efficient management of translations and region-specific content from a single dashboard.

Enterprise Organizations with Multiple Brands

Large corporations use multisites to maintain distinct online presences for different departments or product lines. For example, a business may serve two distinct audiences such as B2B and B2C audiences where they sell different products. This streamlines administration while allowing for specialized content tailored to each audience's needs.

Non-profit organizations needing mini-sites

Nonprofit organizations often have one-off initiatives or programs better suited to stand alone websites. Others have legal requirements to separate their 501c3 filing work from other activities, such as political work. The firewall between sites offered with a multisite allows for those organizations to serve both needs with minimal spin-up and maintenance costs.
