E-commerce & WooCommerce Expert
E-commerce tolerates no approximation: every extra tenth of a second loading time costs conversions, every friction in the payment funnel drives buyers away. Xavier Kain develops bespoke WooCommerce shops in PHP/WordPress optimised for performance (Core Web Vitals, LCP < 2.5s) and conversion. He integrates Stripe, PayPal, delivery solutions and CRM tools.
My e-commerce shops systematically include: on-page SEO optimisation (product titles, unique descriptions, JSON-LD product schemas), Google Shopping and Meta Ads integration, category pages optimised for long-tail SEO, and Plausible or GA4 dashboards to drive sales. I handle migration from Shopify, PrestaShop or Magento if needed, preserving existing URLs and earned SEO.

Frequently asked questions
WooCommerce or Shopify, which to choose for my shop?
WooCommerce offers more flexibility and control (independent hosting, full customisation, variable costs) but requires technical maintenance. Shopify is simpler to manage but with higher recurring costs and less freedom. For shops with over 500 products or specific needs (B2B, configurators), WooCommerce is generally preferable.
How long does it take to create an online shop?
A standard WooCommerce shop (catalogue, Stripe/PayPal payment, delivery) is generally delivered within 1 to 3 weeks depending on the number of products and required integrations. Each project is unique.
How to improve conversions on an existing shop?
The main levers are: checkout optimisation (reducing steps), mobile speed improvement, adding customer reviews, abandoned cart recovery, and testing new product pages.
WooCommerce or Shopify: which to choose for my online shop?
WooCommerce (based on WordPress) is more flexible, has no transaction fees and gives you full control over your data. Shopify is more turnkey but involves monthly costs and transaction fees. For complex shops with specific needs, WooCommerce is generally the best option.
How to optimise an e-commerce site for SEO?
The keys to e-commerce SEO are: a logical category structure, unique and detailed product pages, optimised loading time, Schema Product tags for rich snippets, and clean URLs. Customer reviews and a themed blog also strengthen domain authority.
Can you sell in Europe with different VAT rates on WooCommerce?
Yes, WooCommerce natively handles multi-country VAT through specialised plugins like WooCommerce EU VAT Compliance or Avalara. These tools automatically calculate the buyer's country VAT (OSS directive) and manage European tax filings.
