How can I improve loading speed on a WordPress website?
"Hi everyone, I'm working on a WordPress site that feels a bit slow on mobile and desktop."
"I want to improve the loading speed and overall performance, but I'm not sure which optimizations will give the best results."
"Can anyone recommend: * Best caching plugins * Image optimization methods * What settings to adjust for faster loading * Any tools to diagnose what's slowing things down"
Focus on caching at multiple layers: page caching (WP Rocket, LiteSpeed Cache, W3 Total Cache), object caching (Redis or Memcached), and server-level caching. Optimize images by resizing to needed dimensions, compressing (lossy or lossless), serving modern formats (WebP/AVIF), using responsive srcset, and enabling lazy-loading. Adjust settings to minify and defer CSS/JS where safe, implement critical CSS, enable GZIP/Brotli compression, use HTTP/2 or HTTP/3, and upgrade to the latest stable PHP. Audit and remove unused plugins, host on fast infrastructure, enable a CDN, and monitor performance continuously with diagnostic tools.
