Ecommerce SEO for an Office Supplies Store in South Africa: +67% Organic Traffic in 6 Months

How a 20,000-SKU BigCommerce store went from technical debt to consistent organic growth — through a full SEO and development overhaul.

Industry: Office Supplies

Platform: BigCommerce

Market: South Africa

Duration: 6 months

The Challenge

When we started working with this South African office supplies retailer, the site had been running for several years — but organic search was barely contributing to revenue. With over 20,000 product SKUs on BigCommerce, the scale of the catalogue made every technical issue multiply.

The problem was not the products or the brand. It was the foundation.

What we found on day one:

• Mobile PageSpeed score of 44/100 — Largest Contentful Paint at 14 seconds
• Redirect chains of 3–4 hops across category and product URLs
• ~2,400 filter-generated pages with missing or broken canonical tags
• Zero structured data across the entire site — no Product schema, no BreadcrumbList
• XML sitemap referencing 1,200+ non-indexable URLs
• 312 toxic backlinks suppressing domain authority
• 30+ UX friction points in the shopping and checkout flow
• Google Search Console not connected; GA4 ecommerce events not firing

What We Did
