# Core Web Vitals Expert.

Daniel Paz is a Core Web Vitals expert and WordPress performance engineer, CEO of WebOption and a speaker at WordCamp Brazil, WordCamp Canada and WordCamp US. As a consultant he finds out why your LCP, INP or CLS fail in field data and hands your team a plan it can ship.

Core Web Vitals

Google judges Core Web Vitals on real visits, at the 75th percentile of CrUX field data. A green Lighthouse run does not change that number. Fixing what slows down real users does.

## The three metrics

01

LCP

Largest Contentful Paint. Good at 2.5 seconds or less. On WordPress it is usually a server, cache or hero image problem.

02

INP

Interaction to Next Paint. Good at 200 ms or less. Long JavaScript tasks from themes, page builders and third-party tags are the common cause.

03

CLS

Cumulative Layout Shift. Good at 0.1 or less. Fonts, ads, embeds and images without reserved space make the layout jump.

## How I work with you

I audit, advise and train your team myself. When you need hands on the code, the [WebOption team](https://weboption.com.br/performance-seguranca/)
 implements the plan.

### Core Web Vitals audit

I review your CrUX and real-user data, then trace each failing metric to its cause in hosting, theme, plugins or scripts. You get a signed report with fixes ranked by expected impact.

### Advisory and code review

Ongoing support for your developers or agency. I review pull requests, plugin choices and release plans against the metrics before they reach production.

### Team training

Workshops for your developers on how WordPress affects LCP, INP and CLS, using your own site as the example. It is the same approach I teach on the WP Alta Performance channel.

## How it works

From the first call to a plan your team owns.

1. 01### Discovery call Goals, traffic, stack and constraints. Thirty minutes.
2. 02### Field data CrUX and real-user metrics show which metric fails, on which templates and devices.
3. 03### Diagnosis Code and infrastructure review to tie each failing metric to a cause.
4. 04### Plan and handover Ranked fixes, a session with your developers and follow-up advisory if you want it.
