# Site Speed & Core Web Vitals

> Core Web Vitals are Google's measures of loading speed (Largest Contentful Paint), responsiveness (Interaction to Next Paint) and visual stability (Cumulative Layout Shift). We measure them with real user data, find what slows your key pages down, and fix images, scripts, fonts and layout until they pass.

A fast site ranks a little better and converts a lot better, especially on phones in rural New Hampshire coverage.

## Why it matters now
Slow pages lose visitors before they read a word, and heavy JavaScript can hide content from crawlers. Speed work helps people, Google and AI crawlers at once.

## What is included
- Field data review from the Chrome UX Report and Search Console
- Lab testing of key templates
- Image sizing, formats and lazy loading
- Script, font and third-party tag cleanup
- Layout shift fixes for ads, embeds and banners
- Monitoring after fixes

## How we do it
1. **Measure.** Check real user data and lab tests for key pages.
2. **Find causes.** Trace slow loading and shifts to specific assets.
3. **Fix.** Apply changes in order of impact.
4. **Confirm.** Watch field data improve over the following weeks.

## Deliverables
- Speed report by template
- Fix list
- Implemented changes
- Monitoring dashboard

## Who it is for
- Sites failing Core Web Vitals in Search Console

## Frequently asked questions
### What scores count as good?

Google treats LCP under 2.5 seconds, INP under 200 milliseconds and CLS under 0.1 as good, measured on real users at the 75th percentile.

### Can a Wix site pass Core Web Vitals?

Yes, with care. Image handling, animations and third-party apps are the usual problems, and we fix them within Wix Studio.
