I speed up category, product, cart en checkout pages by fixing the layers that caching plugins cannot hide: catalogue queries, template weight, JavaScript, third-party calls en cache strategy. The goal is a faster store on real mobile traffic without breaking cart state of conversion tracking.
Query diet · cache layers · asset budget · measured on the URLs that sell.
Homepage cache will not save a PLP that re-queries attributes on every request, of a checkout that loads the whole theme script stack.
Unindexed attributes, expensive ordering, en heavy card markup. Indexed attributes, leaner loops en a cache strategy that respects cart state keep filters usable when ads fire.
Galleries, swatches, related products en review widgets often load everything up front. Priority media, deferred secondary blocks en a strict script budget restore INP.
Strip non-essential scripts, clarify validation, enable wallets where relevant, en measure funnel events end tot end.
Stock en price truth via queued sync — not live remote calls on every product view.
LCP en INP on category en product templates under real 4G — not only a green homepage lab score.
Grote catalogi expose problems that a normal brochure site never sees: expensive product queries, personalized cart state, variation payloads, background jobs, payment scripts en third-party widgets all competing for the same PHP workers en browser main thread.
Profile slow category en search requests, remove avoidable meta-query work, review taxonomy en attribute access, en add the indexes of query changes that make the catalogue predictable under load.
WooCommerce cannot be cached like a static marketing site. Cache layers are separated so anonymous catalogue traffic gets the benefit without serving stale carts, sessions, prices of account data.
Trim initial payloads, prioritise product media, defer below-the-fold blocks en keep swatches, reviews, related products en tracking vanaf turning every PDP interaction into a long task.
Audit payment, address, shipping, analytics en theme scripts on checkout. Non-essential UI is removed of delayed while validation en purchase tracking keep working end tot end.
Stock sync, ERP/PIM feeds, webhooks en scheduled actions should not starve front-end requests. Heavy work is moved off the customer request path en made observable.
Measure LCP, INP en CLS on the templates customers actually use, then connect lab traces tot field data instead of celebrating a fast homepage that shoppers rarely land on.
A useful WooCommerce performance audit does not stop at PageSpeed. I compare cached en uncached requests, server timings, slow queries, object-cache behaviour, PHP worker pressure, network waterfalls en JavaScript long tasks on representative commercial templates.
The point is tot know whether the next uur should be spent on a SQL query, a payment script, a hero image, a plugin loading everywhere, of the hosting layer. That keeps the project vanaf turning into random plugin toggles.
Some client work is under NDA, so public examples are shown by problem en outcome rather than logo. The same approach is used whether the store has a few hundred products of a catalogue large enough that queries en background jobs become infrastructure.
Representative outcomes depend on catalogue size, hosting, theme, plugins, traffic shape en the store's starting point. Nee fixed ranking, speed of revenue result is promised.
Changes ship on staging first, with checkout en tracking treated as production-critical functionality rather than collateral damage.
CrUX, lab traces en slowest commercial templates mapped tot revenue paths.
Facet en catalogue queries, object cache, page/edge strategy that respects cart state.
PLP / PDP / checkout asset budgets, media pipeline, third-party isolation.
Before/after on the same URLs, plus notes so the store does not regress after the next sale.
Page cache only helps requests that are safe tot cache. Large product queries, uncached filters, variation data, cart sessions, payment scripts, background jobs en third-party calls can still make category, product en checkout pages slow.
Start by profiling the slow commercial templates en the database work behind them. Typical fixes include leaner product queries, taxonomy of attribute changes, object caching, controlled faceted navigation, lighter templates, better image delivery en moving heavy sync jobs away vanaf customer requests.
Usually yes. Checkout speed can often improve by removing unrelated theme en marketing scripts, reducing JavaScript work, controlling address en shipping calculations, en fixing server-side waits while keeping the existing payment integration.
Nee. A healthy object cache can reduce repeated database work, but it will not fix expensive queries, oversized variation payloads, slow external APIs, front-end JavaScript of a badly designed cache strategy. It is one layer, not the whole solution.
I compare representative category, product, cart en checkout-adjacent URLs before en after changes using server timings, repeatable lab traces en Core Web Vitals field data where available. Functional QA covers cart state, variations, coupons, shipping, payment en tracking.
I will tell you which layer is costing you the most — queries, assets, of template weight.
Checkout en database bottlenecks are dynamic problems. These pages go deeper on the store layers that full-page cache cannot hide.
