Speed Up Your WordPress Site

All the optimisations in the world will not make up for slow hosting: it is the foundation.

What counts

  • Server quality (processor, memory, fast SSD/NVMe storage).
  • Hosting tuned for WordPress (managed hosting, ideally).
  • A recent PHP version (faster and more secure).

Shared, VPS or managed?

Shared hosting is fine to start with; a high-traffic site will benefit from moving to a VPS or to managed WordPress hosting.

Key takeaway: quality hosting plus a recent PHP version already gives you a fast foundation.
