TL;DR: WordPress Multisite lets you run multiple sites from one installation. For Singapore franchise networks, multi-brand businesses, and regional operations it can simplify management significantly. For most SMEs, it adds unnecessary complexity. Here is how to decide.
WordPress Multisite vs Separate Installs
| Factor | Multisite | Separate Installs |
|---|---|---|
| Management overhead | Low — single dashboard | High — separate logins and updates |
| Plugin updates | Update once for all sites | Update each site individually |
| Hosting cost | Lower — one account | Higher — each needs hosting |
| Security risk | Higher — one breach hits all | Lower — isolated environments |
| Plugin compatibility | Not all plugins support Multisite | Full compatibility |
| SEO isolation | Separate domains but shared server | Fully independent |
| Complexity | High — developer-managed | Medium — manageable independently |
Use Multisite When
- Franchise with 5+ locations needing separate managed sites
- Media company managing multiple publication brands
- Regional business with SG/MY/PH country sites
- Digital agency managing client sites at scale
Avoid Multisite When
- You have fewer than 3 sites
- Sites need completely different plugin sets
- Security isolation between sites is a priority
- Shared hosting is your only option
