Web hosting for beauty spas — Gift vouchers turn a brochure site into a shop

A treatment menu with durations and prices, packages, gift vouchers and an online booking calendar. Read as a content brief that is straightforward. Read as a performance brief it contains a hard edge: the moment vouchers are sold, part of the site becomes uncacheable by design.

That distinction is the single most useful thing to understand about hosting a spa site, because it explains why a site that felt quick as a brochure feels different once it is taking money — and why the answer is CPU and memory rather than a faster disk.

Below: how to measure a long treatment menu, what a voucher checkout actually costs, why December is your load test, and what the certificate is really doing on the payment page.

A cached page is identical for everyone, which is exactly why a basket cannot be cached. From the moment a voucher goes in a cart, that visitor's pages are rendered individually: PHP runs, the database is queried, the session is written. Multiply by a busy evening and you have a genuine CPU load where before you had none.

AccelerateWP and Redis object caching on the managed WordPress and store plans reduce the cost of each render, because query results are held in memory even when the page itself cannot be. That is the right tool for a checkout, and it is a different mechanism from page caching entirely.

Every plan includes free SSL that issues and renews itself, so the padlock on a payment page is never a task and never an invoice line. HTTPS runs end to end, which is the baseline any card processor expects before it will talk to you.

Keep the confirmation mail on your own domain as well. Outbound goes through MailChannels with SPF, DKIM and DMARC configured, which is what stops a voucher code being filtered into a spam folder on the one occasion it genuinely matters.
