# Web Performance

For marketplaces, publishers, SaaS dashboards and e-commerce sites, milliseconds turn into conversions and search rankings. This section is for frontend performance leads, web developers, platform engineers and SEO teams who want pages to load fast for users in every region, including on mobile networks.

Articles cover Core Web Vitals (LCP, INP, CLS), image delivery and formats such as WebP and AVIF, responsive images, Brotli, gzip and zstd compression, HTTP caching headers for websites, JavaScript and font delivery, and CDN setups for WordPress, Next.js and similar stacks. Image-heavy sites with millions of SKUs will find guidance on resizing and caching at the edge. For protocol-level speedups, see [networking and ISP](https://blog.blazingcdn.com/networking-isp?hsLang=en).
