The website loading speed increases by 1 second, the conversion rate may decrease by 7%. Increasing the loading speed is a direct means to improve user experience and conversion. Here are 10 practical optimization techniques.
1. Enable HTTP/2
HTTP/2 supports multiplexing, allowing parallel loading of multiple resources, significantly reducing page load time. It is recommended to enable HTTP/2 with Nginx or Apache.
2. Image Compression
Use TinyPNG, ImageOptim, and other tools to compress images. It is recommended to use WebP format, which is more than 30% smaller than JPEG.
3. Enable Gzip Compression
Enable Gzip compression for HTML, CSS, and JS text resources, which can reduce 60-80% of the transmission size.
4. CDN Acceleration
Place static resources (images, CSS, JS) on CDN, so users can retrieve from the nearest node to reduce latency.
5. Browser Cache
Set the Cache-Control and ETag headers to allow the browser to cache static resources and reduce duplicate requests.
6. Reduce HTTP requests
Merge CSS and JS files, use CSS Sprite to merge small icons, reduce the number of requests.
7. Lazy loading
Images and iframe heavy elements use lazy loading, only loading the content in the visible area.
8. Font optimization
Use the system font or load a local font to avoid rendering block caused by external fonts.
9. Simplify CSS and JS
Delete unused CSS and JS code. Use tools (such as PurifyCSS, Terser) to compress the code.
10. Choose a high-performance server
Server performance and network bandwidth directly affect loading speed. It is recommended to use the high-performance Go architecture of AnQi CMS, which can run smoothly with just 2 cores.
Performance advantages of AnQi CMS
The AnQi CMS has performed multiple performance optimizations at the architectural level: Go native concurrency, built-in caching, automatic staticization, resource compression, etc., with performance out of the box far superior to traditional PHP CMS.
Summary
To improve website loading speed, optimization needs to be carried out from multiple levels. Choosing a high-performance CMS system is the foundation, and combining with front-end optimization techniques can achieve **results.
