Should You Be Using WordPress Multisite?

Tuesday 16 December 2014, by Lewis Swift

Should You Be Using WordPress Multisite?

What is WordPress Multisite?

“Multisite is a feature of WordPress 3.0 and later versions that allows multiple virtual sites to share a single WordPress installation. When the multisite feature is activated, the original WordPress site can be converted to support a network of sites." (From the WordPress Codex)

In other words, Multisite can allow people who run multiple WordPress websites to run all of those websites from a single dashboard.

Each of the ‘sub-sites’ will, by default, be either in a subfolder (e.g. mysite.com/subsite1) or on a subdomain (e.g. subsite1.mysite.com). But you can map unique domains (e.g. www.mynewsite.com) over your sub-sites so that they don’t necessarily appear to be connected.

What are some examples of WordPress Multisite websites?

At the time of writing, the following sites use WordPress Multisite functionality to manage a network of related sites from one ‘Super Admin’ dashboard:

  • BBCAmerica.com - each show is a sub-site with its own custom child theme

  • WordPress.com - each section (Themes, Support, etc) is a sub-site of the main Wordpress.com website

  • EduBlogs.org - each of the individuals blogs is a sub-site of the EduBlogs.org website

What are the benefits of using WordPress Multisite?

  • There’ll be less space taken up on your server by multiple WordPress websites if you run them all under Multisite, as they will share many files and will all share the same database

  • You’ll only have to go through the update process once for each theme, plugin or core Wordpress update, rather than updating each of your sites’ plugins and themes individually

  • You’ll only have to worry about backing up one database, rather than backing up each separate database for each website that you own

  • Your overall site management time will be cut down, as will the amount of time it takes to add a new site to your collection

  • You don’t have to worry about any SEO issues as all sites within a Multisite install are seen as separate if they have their own domain names - and you can quickly install an SEO plugin on all sites at the click of a button!

What are the disadvantages of using WordPress Multisite?

  • By default, user profiles and login details are going to be the same for all sites, so anyone who registered on one of your sites will have access to all of them (unless you add a plugin that changes this default behaviour)

  • You might find that some plugins or themes are not designed to work with Multisite websites, so make sure to check a plugin or theme’s documentation carefully before installing

  • You can’t use different versions of a plugin or theme on different sites within a Multisite installation; whichever version is installed is available to all sites

  • Having multiple Wordpress websites sharing one database can potentially tax your server’s resources on high-traffic sites

Who should be using WordPress Multisite?

Professional WordPress developers who are managing several sites for clients might find Multisite useful, as all updates and installations could be managed from one Super-Admin dashboard.

Companies or organisations that have lots of branches or divisions could benefit from using Multisite to allow each branch or division to manage its own sub-site’s content. The company or organisation would still have overall control of all of the sites.

Who should NOT be using WordPress Multisite?

Anyone who’s just getting started with WordPress should steer clear of the Multisite feature until they’re more experienced.

Also, anyone who only has one or two websites that they’re running probably doesn’t need to bother with Multisite.

What are the alternatives to using WordPress Multisite?

If a WordPress Multisite setup doesn’t sound quite right to you, there are some other options.

Plugins like ManageWP and MainWP can be added to your main site and connected to other WordPress websites that you own so that you can manage them all from one location. Updates and security scans can be done across all sites with one click.

These plugins do not allow you to manage content on your other sites from your main site, however.

There are also dedicated WordPress hosting options, like Flywheel, which provide one control panel for managing multiple WordPress websites. This is generally more expensive than standard hosting because the hosting company takes care of all updates and security monitoring for you. This is also known as ‘managed hosting’.
