Core Web Vitals are three measurements of how fast, responsive and stable your pages feel to a visitor. Google recommends good scores for Search success and a better user experience. For a local business, the practical point is simple: if your site is slow on a phone, people leave before they call.
What are the three metrics and the targets?
Google’s documentation sets these targets:
| Metric | Measures | Good target |
|---|---|---|
| Largest Contentful Paint (LCP) | How fast the main content loads | Within 2.5 seconds |
| Interaction to Next Paint (INP) | How quickly the page responds to taps and clicks | Under 200 milliseconds |
| Cumulative Layout Shift (CLS) | How much the layout jumps around while loading | Below 0.1 |
Google says these metrics are part of page experience, which its core ranking systems aim to reward. They are one signal among many, not a substitute for useful content.
How do you measure them?
- Open the Core Web Vitals report in Search Console to see how your pages perform for real visitors.
- Run your main pages through PageSpeed Insights. Test your home page, your top service page and your contact page, on mobile first.
- Note which metric fails and which element is responsible.
What usually slows down a local business site?
These are the usual suspects on WordPress sites, including those built with page builders. They’re patterns we see often, so check them against your own reports rather than assuming:
- Huge images. A photo straight from a phone camera can be several megabytes. Resize and compress before uploading, and use modern formats where your setup supports them.
- Too many plugins and add-ons. Each can add scripts and styles. Remove what you don’t use.
- Heavy sliders, animations and pop-ups. They often delay the main content and hurt responsiveness.
- Cheap or overloaded hosting. A slow server delays everything. Check your server response in the test results.
- No caching. A caching plugin or host-level cache can cut load time noticeably.
- Layout jumps. Images or embeds without set sizes, late-loading fonts and banners that push content down cause CLS.
What should you fix first?
- Compress and resize the largest image on each key page, especially the one at the top.
- Remove unused plugins, widgets and third-party scripts.
- Turn on caching.
- Set width and height for images and embeds so space is reserved.
- Retest, then work down the report.
How long before it shows up in reports?
Lab tests update immediately, but field data in Search Console reflects real visits over time, so it can take weeks to update. Don’t expect an overnight change.

Frequently Asked Questions
What is a good Core Web Vitals score?
Google’s targets are LCP within 2.5 seconds, INP under 200 milliseconds and CLS below 0.1.
Do Core Web Vitals affect rankings?
Google says they are part of page experience, which its core ranking systems aim to reward, and recommends good scores. They are one factor among many, so great content still matters more.
Is mobile or desktop more important?
Check mobile first. Many local searches happen on phones, and mobile connections are usually slower, so problems show up there first.
Do page builders like Elementor hurt speed?
They can add weight if used heavily. Use fewer widgets, avoid heavy effects on key pages, compress images and use caching, then test real results rather than assuming.
Where do I check my scores for free?
Use the Core Web Vitals report in Search Console and Google’s PageSpeed Insights.
