WordPress Multisite lets you run many websites from one WordPress installation. It sounds convenient, but it adds complexity. Here's when it genuinely helps and when simpler setups are better.

How Multisite works

One WordPress installation hosts a network of sites, each with its own content and settings, sharing the same core files, themes and plugins. Sites can live on subdomains (city.example.com), subfolders (example.com/city/) or separate domains.

When it can make sense

• Franchises or branches that need their own mini-sites with shared branding
• Organisations with many departments, such as schools, universities and hospitals
• Networks of similar sites managed by one team with shared themes and plugins

When it's usually not the right choice

• Just a few unrelated websites: separate installations are simpler
• Multiple languages: a multilingual plugin on one site is usually better. See multilingual WordPress.
• Several locations for one business: location pages on a single site are often enough
• Sites needing very different plugins or hosting

Things to consider

• Plugins: not all plugins support Multisite, and a plugin problem can affect every site
• Hosting: one server handles all sites, so resources and backups need planning
• Moving a site out later is possible but more work
• User management: network admins vs site admins
• SEO: each site needs its own titles, sitemaps and structure; avoid duplicating content across sites

The practical answer

Most small and medium businesses are best served by a single, well-structured WordPress site. Multisite is a tool for organisations managing many similar sites with a central team. If you're unsure, describe your setup and a developer can recommend the simplest option that works; see WordPress website development.
