Web hosting for fashion boutiques — the mobile checkout is the whole benchmark

A boutique's traffic profile is lopsided in a way that ruins generic advice. Most browsing and most buying happens on a phone, often on mobile data, often in a spare five minutes. The pages that get the traffic are cacheable; the page that takes the money is not.

So the score on your homepage is close to irrelevant. What matters is what a phone experiences between tapping a size and seeing a payment confirmation, and that path runs through variation queries, cart fragments and a checkout that never comes out of cache.

This page is about instrumenting that path, in order, and about the specific things on a WooCommerce boutique that make it slow.

A variable product with four colours and six sizes can fire an admin-ajax request every time a shopper changes a swatch, and on a large catalogue that query is not cheap. The symptom is a page that loads quickly and then feels sticky when touched — poor responsiveness rather than slow loading, which is why a good lab score can sit on top of a frustrating page.

Redis object caching is the specific fix: it keeps the repeated variation and option lookups in memory instead of returning to the database for each one. Measure it by tapping through five swatches with the network panel open, before and after.

One change, one measurement. Retest after each, keep the median of three lab runs, and give field data weeks to catch up. A change that improves a lab score while making the phone experience worse is common enough to be a category of its own, and only real-user data catches it.

Test on a staging clone before it reaches customers. Clone, change, measure, push — and if the number moves the wrong way, throw the clone away and nobody bought anything through the experiment.
