Upgrading your BigCommerce store's Cornerstone theme ensures a secure, high-performing, and future-proof eCommerce experience. Here's why it's essential:
Newer versions patch vulnerabilities and resolve known issues, protecting your store from cyber threats and ensuring smooth operations without unexpected downtime.
Optimized code reduces page load times, boosting SEO rankings and conversion rates.
Stay compatible with platform updates like advanced checkout options, headless commerce, and API integrations that drive revenue growth.
Modern Cornerstone versions deliver pixel-perfect experiences on all devices, catering to 50%+ of shoppers who browse via mobile.
Updated themes align with Google's latest standards, improving search visibility, user experience, and compliance with WCAG guidelines for broader reach.
Unlock new templates, styling options, and drag-and-drop tools to create a unique brand identity without starting from scratch.
Avoid obsolescence—outdated themes lose support, forcing costly migrations later. Upgrading now extends your store's lifespan cost-effectively.
