For solopreneurs, who often manage their own sites, understanding Core Web Vitals is key to improving SEO and keeping visitors engaged. Introduced by Google as part of its page experience signals, Core Web Vitals is a set of specific metrics that assess the quality of user interaction. Here's a simple guide to help you make sense of these vitals and optimize your website accordingly.

What are Core Web Vitals?

Core Web Vitals are a subset of Google’s ranking factors that measure how users experience your website. As of 2025, the three key metrics are:

• Largest Contentful Paint (LCP): measures loading performance.

• First Input Delay (FID): measures interactivity.

• Cumulative Layout Shift (CLS): measures visual stability.

Google emphasizes these because they reflect real-world experience. If your website performs poorly in these areas, you risk lower search rankings and higher bounce rates.

Largest Contentful Paint (LCP): Keep Load Times Under 2.5 Seconds

LCP tracks how long it takes for the largest content element (e.g., an image or heading) to appear on screen. A slow LCP frustrates users and sends them away. To improve this score:

• Use faster hosting

• Optimize images by using WebP or AVIF formats

• Implement lazy loading

• Minify CSS and JavaScript

• Tip: Tools like Google PageSpeed Insights can show exactly what's slowing down your site.

First Input Delay (FID): Make Your Site Responsive

FID measures how quickly your site reacts when a user clicks or taps on something. Google recommends keeping FID under 100 milliseconds. Although Google is transitioning from FID to Interaction to Next Paint (INP) for better accuracy, reducing JavaScript execution time remains crucial. To optimize:

• Break up long JavaScript tasks

• Defer unused scripts

• Use a lightweight theme

• For solopreneurs using platforms like WordPress, consider disabling unnecessary plugins to improve performance.

Cumulative Layout Shift (CLS): Stop Unexpected Page Movements

CLS gauges how much the layout shifts while the page is loading. High CLS values create a jarring user experience. Keep CLS under 0.1 by:

• Always specify image and video dimensions

• Avoiding dynamic content that pushes text around

• Preloading fonts to prevent layout changes

A stable layout builds trust, especially for users browsing on mobile devices.

How to Monitor Your Core Web Vitals

Use Google Search Console under the “Core Web Vitals” report to see how your pages perform. Combine this with Lighthouse, Web.dev, and Chrome DevTools for detailed diagnostics.

Why Solopreneurs Should Care

Improving Core Web Vitals not only helps you rank higher on Google but also keeps your visitors happy. A recent Backlinko study (2024) found that sites ranking on the first page of Google had 20–30% better Core Web Vitals performance than those on page two. For solopreneurs competing with bigger brands, this performance edge can make a real difference.
