A slow site costs twice: it loses visitors who leave before it loads, and it weakens the experience signals Google reads. Speed is not vanity, it is a factor in both ranking and conversion, and in B2B it shapes the first impression a serious buyer has of you.
What Google actually measures: Core Web Vitals
Google retired the standalone "page experience" ranking system in 2023, but the Core Web Vitals remain the concrete way it measures experience, and they feed into ranking. Three metrics matter:
- LCP (Largest Contentful Paint): how long the main content takes to appear. Target under 2.5 seconds.
- INP (Interaction to Next Paint): how quickly the page responds to interaction. It replaced FID in 2024.
- CLS (Cumulative Layout Shift): how much the layout jumps while loading. Target under 0.1.
The fixes that move the needle
- Images: compress, serve modern formats (WebP/AVIF), size them correctly and lazy-load below the fold. This is the single biggest win on most sites.
- Hosting and CDN: a fast server and a content delivery network cut time-to-first-byte, especially for international audiences.
- Render-blocking resources: defer non-critical JavaScript and CSS so the main content paints first.
- Caching: browser and server caching stop repeat visitors from downloading everything again.
- Third-party scripts: each tag, chat widget and tracker adds weight. Audit them and drop what does not earn its place.
Speed as a system, not a one-off
The trap is optimizing once and letting speed rot as the site grows. New pages, new scripts and new images undo the work. Speed needs monitoring, the same way you monitor any other part of the operation.
