Comprehensive Guide to Setting Up WordPress Multisite in 2025

Initial Considerations: Hosting, Domain, and SSL Setup

Before diving into the technical aspects of setting up a WordPress Multisite, it’s crucial to lay the groundwork properly. A robust hosting solution is the first step. WordPress Multisite demands more from your hosting due to its complexity and the potential volume of traffic across network sites. Opting for a host that offers dedicated support for WordPress Multisite can simplify technical hurdles and provide the necessary resources for smooth operation.

In addition to hosting, choosing between subdomains and subdirectories will affect your site’s structure and SEO. Subdomains (site1.yourdomain.com) are treated as separate entities by search engines, while subdirectories (yourdomain.com/site1) are seen as part of the same site, which might influence your SEO strategy. Whatever your choice, ensuring your domain is properly registered and your hosting is configured to support it is key.

Lastly, securing your network with SSL is non-negotiable. SSL encryption not only protects data transfer on your sites but also boosts your SEO and trustworthiness in the eyes of your visitors. Most hosts offer easy SSL certificate installation, so make sure your entire network is covered.
