Core Web Vitals Review

Review Core Web Vitals with SEO MCP, identify weak page groups, and connect experience signals to actionable page and template work.

SEO MCP exposes Core Web Vitals records so an AI agent can group weak pages, compare patterns, and combine experience signals with crawl evidence. Treat these metrics as diagnostic inputs, not isolated scores.

Review prompt

Review Core Web Vitals for [PROJECT].

1. Show the measurement scope and available records.
2. Group pages by URL pattern or template.
3. Identify the weakest LCP, INP, and CLS groups.
4. Compare the patterns with response time, page type, and image findings where available.
5. Recommend the next diagnostic check for each group.

Do not claim a root cause unless the available data proves it.

Main tool

Use list_core_web_vitals after discovering the project with list_projects. Use page or image tools only when the crawl evidence can clarify a pattern.

Interpret the signals

Metric	What it represents	Common investigation direction
LCP	Loading performance of the largest visible element	Server response, render blocking, hero media
INP	Responsiveness to user interactions	Main-thread work, event handling, third-party scripts
CLS	Unexpected layout movement	Unsized media, injected UI, late-loading fonts or components

These directions are hypotheses. Core Web Vitals values alone do not prove which implementation caused the result.

Group before acting

Page-by-page recommendations can hide the real ownership boundary. Ask the agent to group:

Landing pages.
Documentation or article templates.
Product or application routes.
Shared headers, footers, and navigation.
Pages that reuse the same hero asset.

Template grouping turns many affected URLs into a smaller engineering plan.

Validate improvements

Use the same page groups and measurement source before and after a release. Note the time window, sample coverage, and whether results represent field or lab data. A deployment is not proven successful by a single page or a short-lived measurement.
