What Is Core Web Vitals?
Core Web Vitals are three measurements Google uses to describe real visitors' experience on a page. Largest Contentful Paint (LCP) measures loading, Interaction to Next Paint (INP) measures responsiveness to taps and clicks, and Cumulative Layout Shift (CLS) measures how much the layout jumps while loading.
Google's "good" thresholds are an LCP of 2.5 seconds or less, an INP of 200 milliseconds or less, and a CLS of 0.1 or less, measured across real visits. These scores appear in Google Search Console and PageSpeed Insights.
Why Core Web Vitals Matters for Northern Indiana & Michiana Businesses
Most local searches happen on phones, often on cellular connections in parking lots or job sites. A Valparaiso customer who waits on a slow page or taps a button that jumps away is likely to go back and choose a faster competitor.
Page experience is part of how Google evaluates pages, and fast pages also convert better. Improving Core Web Vitals helps rankings, ad landing pages, and leads at the same time.
How Core Web Vitals Works
- Largest Contentful PaintHow quickly the biggest visible element, often a hero image or headline, finishes loading.
- Interaction to Next PaintHow quickly the page responds visually after a visitor taps, clicks, or types.
- Cumulative Layout ShiftHow much content moves unexpectedly as images, fonts, and ads load.
- Field dataGoogle uses data from real Chrome users over the past 28 days, so improvements show up gradually.
A Local Example
A Warsaw boutique's homepage hero image is a 4 MB photo, and its LCP sits around five seconds on phones. After compressing images, serving modern formats, reserving space for the banner, and removing an unused slider script, the page loads in under two seconds and the shop sees more product page visits from mobile searchers.
Getting Started With Core Web Vitals
Open Google Search Console and review the Core Web Vitals report for both mobile and desktop. It groups pages as Good, Needs Improvement, or Poor and names the metric holding each group back. Then run your most important pages, usually the homepage and top service pages, through PageSpeed Insights to see specific recommendations.
Fix the largest issues first. Oversized images are the most common cause of slow loading, so resize and compress them before anything else. Reserve space for images and banners so content stays steady, and remove scripts or plugins that no longer earn their place. After each round of changes, test on a real phone over a cellular connection, then give Google's field data a few weeks to reflect the improvement before measuring again.
Quick Wins to Improve Your Core Web Vitals

- Set width and height on images and embeds to prevent layout jumps
- Remove unused scripts, sliders, and plugins
- Load fonts efficiently and limit font weights
- Check Search Console's Core Web Vitals report monthly
What to Watch For
- Field versus lab. PageSpeed lab scores help diagnose, while field data shows what Google uses.
- Third-party tools. Chat widgets, trackers, and embeds can slow pages; keep only what earns its place.
- Mobile first. Test on a real phone over cellular, where most local visitors browse.
- Gradual updates. Field data covers 28 days, so give fixes a few weeks to show.
