FAQ
Can you optimize both BigCommerce and PrestaShop in one order?
This gig covers one store per order — either BigCommerce or PrestaShop. If you have both platforms, please place two separate orders. Each platform requires a distinct technical approach, so I give each store the full dedicated attention it deserves.
What makes BigCommerce and PrestaShop optimization different from WordPress?
BigCommerce uses the Stencil framework with Handlebars templates, and PrestaShop uses Smarty templating with a hook/override system. Both require platform-specific knowledge most generalist speed optimizers don't have. I work at the code level on both — not just surface-level plugin settings.
What PageSpeed score can I expect for my store?
BigCommerce stores typically reach 90–100 on desktop & 70–90 on mobile. PrestaShop stores on good hosting can reach 90–100 on desktop and 70–90 on mobile. Scores depend on theme complexity, number of modules, and hosting quality. I will give you a specific, honest target after reviewing your store.
My PrestaShop store is self-hosted. Does that affect results?
Yes — positively. Self-hosted PrestaShop gives full server access, which means I can configure GZIP/Brotli compression, server caching, and CDN settings that hosted platforms don't allow. Self-hosted stores often see the biggest improvements because there are no platform restrictions.
Will optimization affect my store's checkout, payments, or orders?
No. Speed optimization is entirely front-end focused — it only changes how your store loads, never how it processes orders or payments. I always back up the store before starting and test every page thoroughly before delivery. If anything looks wrong, I fix it immediately at no charge
Do you optimize PrestaShop module pages like category and product pages too?
Yes. The Standard and Premium packages include optimization of your homepage, category pages, and product pages — the three highest-traffic page types in any e-commerce store. Faster product pages directly reduce bounce rate and increase add-to-cart rates.
What if my score does not improve after delivery?
I offer a satisfaction guarantee on all packages. If you do not see a meaningful improvement — minimum 30% score increase — I will continue working at no extra charge until the target is reached, or provide a full refund. Before/after reports are delivered with every order so results are 100% transp
