SEO constantly changes, but some updates have a bigger impact than others. Google’s Core Web Vitals as ranking signals is one of those changes. Here’s what they are and how they affect your website.
What are Core Web Vitals?
Core Web Vitals are a set of metrics created by Google to measure page experience. The core metrics include:
- Largest Contentful Paint (LCP): how quickly the main content loads.
- First Input Delay (FID): how fast the browser responds after the first user interaction.
- Cumulative Layout Shift (CLS): how stable the layout is while loading.
Why do Core Web Vitals matter?
Google has long said that user experience matters. With Core Web Vitals, this became more explicit: websites that deliver a better experience may gain an advantage in search results.
How to improve your Core Web Vitals
- Improve LCP: speed up loading by optimizing images, using caching and reducing heavy resources.
- Improve FID: reduce JavaScript work on the main thread and defer non-critical scripts.
- Minimize CLS: use fixed dimensions for images and ad blocks to avoid unexpected layout shifts.
