12. WordPress Multisite
Unlike many hosts, we support (and encourage!) the use of WordPress Multisite on all plans.
However, you should be aware that WordPress Multisite networks will use more server, CPU, and memory resources than standard WordPress single installs. So, if you have more than a handful of sites, you might find you need one of the higher plans to meet your WordPress Multisite network’s needs.
There are two types of Multisite installations:
- Subdirectory (ie. mysite.com/sitename)
- Subdomain (ie. sitename.mysite.com)
Please read on to learn why we usually recommend against using subdomains for WordPress.
12.1 Why Subdomains Are DiscouragedLink to chapter 1
There are several performance, SEO, and technical reasons why we recommend going with a subdirectory install whenever possible.
Here are a few:
- Most SEO experts recommend subdirectories to maximize content and domain authority for your site. Google is believed to treat subdomains as separate web sites, which will impact SEO.
- Subdomains have limitations and challenges around SSL support (see below).
- Subdomains usually see higher legitimate bot and crawler traffic, which can increase load and decrease performance (or require higher hosting plans). This is because the bots and crawlers see each subdomain as their own site and may crawl each subdomain simultaneously.
- Subdomains can make it harder to prevent and mitigate DDOS attacks.
12.2 Wildcard SSL for MultisiteLink to chapter 2
In order to serve your domain over HTTPS (which we require), a ‘Wildcard’ SSL certificate for your domain or a certificate that covers all domains and subdomains that you plan to use must be uploaded or added to your domain.
Fortunately, we have you covered there as we now offer free wildcard SSL certificates that you can install on your multisite (both subdomain and subdirectory) with just a few clicks. See the Wildcard Certificates chapter in our Domains doc for details about that.
