FAQs About WordPress Multisite Network

Many of our users have asked us plenty of questions about WordPress multisite network and how to use it more efficiently. Following are the most frequently asked questions that we have answered.

1. Would I be able to better manage my sites with a multisite network?

To be honest, the answer really depends on your usage scenario.

For example, if your websites are not related to each other, then you would be better off with a multiple site management tool, like InifiteWP.

If you manage multiple sites for a restaurant chain, university, or online magazine, then WordPress multisite will be more efficient.

2. Does WordPress multisite make my websites load faster?

Once again it depends on several factors. Better WordPress hosting with plenty of server resources will allow multisite to be faster but then again with these resources, individual WordPress sites will also run faster.

However, on a shared hosting account, traffic spikes will increase memory usage and slow down all websites on the multisite network at the same time. To improve multisite speed, see our guide on WordPress performance and speed optimization.

3. Can I add an online store to a WordPress Multisite Website?

Yes, you can add an online store in WordPress multisite network. Most likely, you will be using an eCommerce plugin like WooCommerce for that, which is compatible with WordPress multisite.

4. Can I install ‘x plugin’ on my WordPress multisite?

Some WordPress plugins may not be compatible with WordPress multisite. Normally, plugin authors mention it on the plugin’s website and you can avoid installing a plugin that may not work on a multisite setup. However, if it is not mentioned, then it is safe to assume that it is multisite compatible.

4. How do I share user logins and roles across the multisite network?

By default, a user who is registered on one site cannot register or be added to another site on the same network. That’s because they are already registered in the shared WordPress database. However, they don’t have any user role privileges on other sites.

You can use third-party plugins like WP Multisite User Sync to sync users across the network. However, you need to be careful as you may end up giving someone admin privileges to a site.
