The Challenge & what Onum Delivered

Design and implement a UX that can handle thousands of SKUs without overwhelming users: clear category hierarchy, high-signal listing pages, and powerful faceted filtering so shoppers can quickly narrow by brand, category, price, stock status, and more. Promote key commercial areas (offers, new arrivals) while keeping performance and SEO tight.

Onum delivered:

  • Custom WooCommerce storefront with mobile-first product grid and clean, scannable PDPs

  • Advanced faceted filters (brand & category drill-down, price, stock) with instant, stable results

  • Smart catalogue architecture: clear categories, “On Sale” and “New” product collections, and featured blocks on homepage

  • Conversion-focused UX: sticky add-to-cart, prominent trust signals, streamlined cart and checkout

  • Performance & SEO foundations: Core Web Vitals tuning, lightweight assets, structured data, optimized metadata and internal linking

  • Scalable merchandising controls for promos and badges so the team can surface the right products at the right time
