How to improve website performance: Best practices for faster sites

Webflow, the visual web‑design platform that lets users build sites without code, released a step‑by‑step performance guide that quantifies the business impact of speed. It points out that visitors expect pages to load in under two seconds and that a three‑second delay can trigger a “back‑button” response, while a one‑second load can deliver up to three times more conversions than a five‑second load. The piece also lists the three Core Web Vitals Google monitors—Largest Contentful Paint, Time to First Byte, and Interaction to Next Paint—along with free tools such as Pingdom, PageSpeed Insights, and Search Console to audit those metrics. The guide then drills into seven actions: compressing images into WebP or AVIF and lazy‑loading them, stripping unnecessary CSS/JS, configuring Cache‑Control headers, pruning third‑party scripts, isolating above‑the‑fold CSS, DNS prefetching, and upgrading hosting or CDN layers.

These recommendations echo a broader industry shift where page‑speed has moved from a nice‑to‑have to a ranking and revenue driver. Competitors like Wix, Squarespace, and Shopify have all begun bundling automatic image optimization and edge‑network caching into their core offerings, responding to Google’s Core Web Vitals becoming a ranking signal in 2021. By publishing a detailed checklist, Webflow not only educates its existing user base but also positions itself as a performance‑aware alternative to traditional CMSs that often require third‑party plugins for similar gains. The emphasis on self‑hosted CDN and custom caching also aligns with the growing demand for low‑latency experiences on mobile networks, especially as 5G rollout expands but still coexists with slower connections.

Looking ahead, Webflow’s audience will likely test these tactics on live projects, which could surface friction points—such as the technical overhead
