Performance

How to Improve Core Web Vitals

Core Web Vitals often look intimidating because the numbers are technical, but the workflow is usually simple: identify what is slow, unstable, or blocking, then fix the biggest offenders first.

Focus on the page's first meaningful experience

Largest-contentful-paint tends to suffer when hero images are too heavy, critical assets load too late, or the server takes too long to respond.

Reduce unnecessary blocking work

Heavy JavaScript, too many requests, and large third-party resources can delay interaction and make a page feel slower than it looks.

Stabilize layout shifts

Layout shift problems often come from images or embeds without dimensions, late-loading banners, or interface elements that push content after the page starts rendering.

Watch page weight and request volume

Even if a page looks visually simple, too many scripts, styles, images, or third-party requests can create mobile performance problems.
