Stop Losing Rankings to a Server Response Time You Could Fix in a Week
A complete Core Web Vitals assessment using both lab and field data, with specific technical recommendations for every metric that is failing.
Core Web Vitals have been a confirmed ranking signal since 2021 and they remain poorly understood. The most common misunderstanding is treating a PageSpeed Insights score as the definitive measure. Lab scores vary from field data (real user measurements) and the discrepancy matters for ranking.
We assess your Core Web Vitals from two angles: lab environment testing using multiple tools under controlled conditions, and field data from Chrome User Experience Report (CrUX) where available. Both are included in the report with a clear explanation of any discrepancies between them.
LCP (Largest Contentful Paint), INP (Interaction to Next Paint), and CLS (Cumulative Layout Shift) are each covered with cause analysis. For LCP, we identify exactly which element is the LCP element on your key page types, what is causing the delay, and specific technical changes that will reduce it.
Deliverable includes a test environment log, per-metric findings, and a prioritized fix list. For most sites, three to five changes account for 80% of the improvement opportunity.
What is included
- Lab environment testing (multiple tools)
- Field data analysis via CrUX where available
- LCP cause identification per page type
- INP analysis (interaction responsiveness)
- CLS identification with element-level specifics
- Resource loading waterfall analysis
- Third-party script impact assessment
- Render-blocking resource identification
- Server response time (TTFB) analysis
- Prioritized fix list with effort estimates
