WooCommerce performance tuning for more conversion
21 November 2024 · 4 min read
WooCommerce is powerful but can be heavy. Without optimisation, webshops become slow, especially with many products or high visitor numbers. Every second of delay costs 7% conversion — for a webshop with €50,000 monthly revenue that is €3,500 loss per month.
At WP Maintainer we install performance tuning for WooCommerce as a specialism. In this article we share our best techniques.
Database optimisation
WooCommerce's database can grow enormously: **Product variations:** Every variable product creates multiple database rows. Use swatches instead of hundreds of variations.
Optimise images
Product images are often 60-80% of the page size: - Use WebP format (25-35% smaller than JPEG) - Implement lazy loading for product galleries - Offer thumbnails in multiple sizes - Use a CDN for images
Cache strategy
WooCommerce and caching are a delicate combination: **DO cache:** - Product pages (for anonymous visitors) - Category pages - Homepage
Use a WooCommerce-compatible caching plugin such as LiteSpeed Cache with built-in WooCommerce rules.
Query optimisation
WooCommerce executes many database queries: - **Limit related products:** Show a maximum of 4-6 related products - **Disable AJAX cart:** Use a page-based shopping cart for fewer AJAX requests - **Optimize product loops:** Use custom loops instead of standard WC queries
Hosting and server
Choose hosting that is suitable for WooCommerce: - PHP 8.2+ for 30-40% faster processing - Redis object caching - Sufficient memory (256MB+ per PHP process) - NVMe SSD for fast database access
