Core Web Vitals Report

The Core Web Vitals Report is a dedicated diagnostic dashboard within Google Search Console that evaluates the real-world performance of a domain’s indexed URLs based on three specific metrics: Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS). The report categorizes pages as “Good,” “Needs Improvement,” or “Poor.” Because Google explicitly uses these metrics as a tie-breaking ranking signal, the Core Web Vitals Report is the ultimate source of truth for technical speed optimization. Any URL flagged as “Poor” is actively bleeding algorithmic authority and requires immediate, aggressive developer intervention.

The Core Web Vitals Report is a specific grading sheet inside Google Search Console that tells you exactly which pages on your website are too slow or too frustrating to use. If a page gets a failing grade, Google will actively push it down in the search results.
