What is Caching?
Understanding Caching in E-commerce
Quick Definition
Caching is a performance optimization technique that stores frequently accessed data in a fast-access storage layer, reducing load times and server processing. In e-commerce, caching helps websites deliver faster page loads, improve user experience, and handle higher traffic volumes by temporarily saving database queries, web pages, and computational results.
Understanding E-commerce Caching
Types of Caching in Online Retail
Browser Caching
Stores static assets like images, CSS, and JavaScript locally in user's browser to reduce repeated downloads.
Page Caching
Saves entire HTML page versions to serve instantly without regenerating from database.
Database Caching
Caches complex database query results to minimize repeated computational work.
CDN Caching
Distributes cached content across global server networks for faster international delivery.
Performance Impact
| Load Time | Conversion Rate Impact |
|---|---|
| 1-second delay | 7% conversion rate reduction |
| 3-second delay | Up to 20% conversion rate drop |
Caching Best Practices
- •Set Appropriate Expiration Times: Balance between fresh content and performance
- •Use Cache Invalidation: Automatically update when underlying data changes
- •Implement Cache Layers: Combine multiple caching strategies for optimal performance
