Magento and WooCommerce both offer solid SEO capabilities, but Magento is often seen as more powerful for larger eCommerce businesses. It has advanced features like better URL customization, metadata control, and faster performance with the right setup. WooCommerce, on the other hand, is more beginner-friendly and easier to manage if you’re not tech-savvy. So, Magento might be better for SEO if you have a big store and the resources to manage it, while WooCommerce works great for smaller stores looking for simplicity.
