Performance SEO (Core Web Vitals)
SEO-focused performance optimization targeting Core Web Vitals
In modern Google Search, performance is not a ranking signal — it is a prerequisite. If your site fails Core Web Vitals in real user conditions, no amount of content or backlinks will produce stable rankings. H-Studio delivers Performance SEO — engineering-level optimization that keeps LCP, INP, and CLS consistently in the green, even as your product grows.
Why Core Web Vitals Decide Rankings
Google evaluates performance based on real user data (CrUX), not lab tests. Core Web Vitals measure:
LCP (Largest Contentful Paint)
Perceived loading speed
INP (Interaction to Next Paint)
Real interaction latency
CLS (Cumulative Layout Shift)
Visual stability
Failing any of them reduces:
Our Approach: Performance SEO as Engineering
Real-World Performance Analysis (Not Lighthouse Only)
We analyze:
This avoids "green Lighthouse / red Google" situations.
LCP Optimization (Above-the-Fold Control)
We engineer:
Result: predictable LCP under real traffic.
INP Optimization (JavaScript & Interaction Control)
INP is now the hardest metric.
We fix:
This is not achievable via plugins — only via code-level engineering.
CLS Stability (Layout Guarantees)
We eliminate:
Stable layout = higher trust signals.
Performance-Safe SEO Architecture (Next.js Focus)
We specialize in modern stacks:
Performance must never break indexing.

FAQ
What's the difference between Performance SEO and general performance optimization?
Performance SEO focuses specifically on Core Web Vitals (LCP, INP, CLS) as ranking factors, not just user experience. We optimize for real user conditions (CrUX data), ensure performance doesn't break SEO (e.g., no content loss during streaming), and maintain long-term ranking stability. General performance optimization often ignores SEO implications.
Why is INP harder to optimize than LCP?
INP measures real interaction latency, which depends on JavaScript execution, React hydration, event handlers, and main-thread contention. Unlike LCP (which is mostly about resource loading), INP requires code-level engineering — optimizing React components, reducing long tasks, managing event handlers, and avoiding unnecessary re-renders. Plugins cannot fix INP.
Can you optimize Core Web Vitals without breaking SEO?
Yes — this is critical. We ensure that performance optimizations (streaming, code splitting, lazy loading) don't break indexing, metadata, or structured data. We avoid optimizations that hide content from crawlers, break canonical URLs, or cause schema loss during hydration. Performance and SEO must work together, not against each other.
How long does Performance SEO optimization take?
A Performance SEO audit takes 1-2 weeks. Full optimization (LCP, INP, CLS fixes, Next.js-specific work) typically takes 4-8 weeks depending on site complexity and current performance state. We prioritize fixes that have the biggest impact on both performance and rankings.
Do you work with sites that already have good Lighthouse scores?
Yes — Lighthouse scores don't always reflect real user conditions (CrUX). We analyze field data to identify gaps between lab and real-world performance. Many sites have "green Lighthouse / red Google" situations where real users experience poor performance despite good lab scores.
