Multisite is a WordPress feature which allows users to create a network of sites on a single WordPress installation. Available since WordPress version 3.0, Multisite is a continuation of WPMU or WordPress Multiuser project.
One of the most misunderstood features in WordPress is WordPress-Multisites. Site owners are drawn to it because it promises to make managing multiple WordPress sites much easier. They often don’t realize that this benefit comes at a cost in terms of flexibility until it’s too late. Multisite can be extremely helpful in certain use cases, while in others it can lead to administrative complexity. It’s important to understand what Multisite is and what problems it was designed to address before you make the decision to use it.
What is WordPress Multisite?
WordPress Multisite is a version of WordPress that allows you to run multiple sites off a single installation of WordPress. It makes it possible to run a network of sites under a single WordPress dashboard.
You can manage everything including the number of sites, features, themes, and user roles. It is possible to manage hundreds, thousands, and even millions of sites this way. The best example of WordPress Multisite is WordPress.com, one of the largest WordPress networks on the Internet.
WordPress Multisite started out as a fork of WordPress designed to enable site owners to easily manage multiple blog sites under a single network. The project was eventually added into WordPress Core during the WordPress 3.0 release. This means any current version of WordPress you use today can be converted into a Multisites installation.
Use it If:
WordPress Multisite is best used when you are building a network of sites sharing similar functionality. Ideally, this similar functionality has been added through plugins, custom applications, or specific server configurations. It also works best when it uses a limited number of themes specifically curated for the purposes of the network, as opposed to allowing members of the network to upload their own custom themes.
If your network consists of widely different WordPress sites in terms of plugins, themes and customization, then Multisite is not a good fit for you.
WordPress.com is, by far, is the largest example of a Multisite network. Other site owners who have had success with Multisite typically have a common motif that ties their network of sites together and lends itself to similar functionality and themes. Universities are one example.
A lot of them use Multisites to provide their staff with a way of posting internal blogs. Real estate companies are another great example. They use WordPress Multisites as an easy way to provide their real estate agents with a basic website. The designs of these sites are the same, only the content is different from realtor to the realtor.
Don’t Use If:
WordPress Multisites emerged at a time when there just weren’t a lot of good options for managing multiple and very different WordPress sites. Fortunately, there are a lot of great options available today to help address this need. So if you find yourself in the position where you are managing many different WordPress sites, you should look into management plugins like Jetpack and ManageWP.
These let you run distinct WordPress instances and centrally managed them all through an intuitive dashboard. You can typically use them to monitor the current status of your sites, globally apply updates across all of your sites, and perform other general maintenance functions like backups.
Multisite Best Practices
So if you find that you are an excellent candidate for Multisites (i.e. you need to offer similar WordPress websites to a large number of users), there are a couple of best practices that you should follow to ensure success.
First and foremost, we recommend that you work with a WordPress consultant who is an expert on scaling WordPress Multisites. If the Multisites network grows, you do need to keep an eye out for the number of server resources your site uses, as well as the upkeep of your database. It’s perfectly manageable as long as you are proactive, and it helps to work with an expert who can guide you through growing your Multisites.
For WordPress Multisite, it’s also important to use a really good hosting provider who already supports the various features of Multisite. At Pressable, for example, we host quite a few large Multisite networks and have developed technology and procedures to ensure our Multisite deployments run smoothly and efficiently.
A hosting provider with a great track record in hosting Multisites deployments will dramatically increase the likelihood of continued success for your projects.
