The #1 PageSpeed Insights Optimization Agency
Expert Google PageSpeed Insights Optimization Services
Performance score engineering, audit resolution, CWV metric tuning, mobile-throttled optimization, and field data improvement — purpose-built for sites that need to reach and maintain 90+ PageSpeed scores.
Google PageSpeed Insights combines Lighthouse lab data with Chrome UX Report (CrUX) field data to give you the most complete picture of your site's performance. A low PSI score doesn't just mean a slow site — it means lost rankings, higher ad costs, and fewer conversions. The challenge is that PSI scores reflect dozens of interacting factors: render-blocking resources, image optimization, JavaScript execution, font loading, server response time, and more. Fixing one audit often reveals another. Our PSI optimization service systematically addresses every audit item to achieve and maintain green scores across all metrics.

Who This Is For
Is Your PageSpeed Score Hurting You?
E-Commerce Stores
Online stores competing for organic product search traffic need 90+ PSI scores to outrank competitors and reduce Google Ads cost-per-click.
Lead Generation Sites
B2B and service businesses where every second of delay reduces form submissions and phone calls. PSI scores directly impact Google Ads Quality Score.
Content Publishers
Content sites competing for featured snippets and top organic positions need fast PSI scores across hundreds or thousands of pages.
Enterprise & Multi-Site
Enterprise organizations where PSI scores vary across brands, regions, and site templates — requiring standardized optimization across the portfolio.
Common Problems
What's Killing Your Score?
Low Performance Score
Scores below 50 indicate significant performance issues affecting users. PSI weighs metrics differently — LCP and TBT account for 50% of the total score — so generic optimizations often miss the highest-impact fixes.
Guide: Speed Testing ToolsFailed Lighthouse Audits
Red and orange audit items in Opportunities and Diagnostics indicate specific optimization opportunities. Each failed audit includes an estimated savings value — but implementing fixes without understanding dependencies can break functionality.
Guide: Core Web VitalsMobile vs Desktop Score Gap
Mobile scores are typically 20–40 points lower than desktop because PSI simulates a mid-tier Moto G Power on slow 4G (1.6 Mbps). This throttling exposes JavaScript bloat, unoptimized images, and render-blocking resources that desktop tests mask.
Guide: Platform Speed ComparisonField Data Failures (CrUX)
Real-user Chrome UX Report data showing poor experience across LCP, INP, or CLS. Field data comes from actual users over 28 days — it can't be faked and directly feeds Google's ranking signals.
Guide: Core Web VitalsRender-Blocking Resources
Stylesheets and scripts that block first paint, inflating FCP and LCP. Every render-blocking resource adds network round trips before users see content — and PSI penalizes each one.
Service: LCP OptimizationExcessive JavaScript Execution
Long main-thread tasks from third-party scripts, analytics, chat widgets, and framework hydration. PSI's TBT metric captures every task over 50ms — and TBT accounts for 30% of the performance score.

How We Get You to 90+
Complete Audit Resolution
We systematically address every failed PSI audit item — Opportunities and Diagnostics — ordered by score impact. Each fix is tested in isolation to prevent regressions before deployment.
Mobile-First Optimization
We optimize specifically for PSI's mobile throttling profile: Moto G Power on slow 4G. This means aggressive JavaScript budgets, responsive images with proper sizing, and critical CSS extraction.
Resource Optimization Pipeline
We compress, defer, lazy-load, and eliminate unnecessary resources. Images get modern formats (WebP/AVIF), scripts get code-split and deferred, CSS gets critical-path extraction, and fonts get proper loading strategies.
Field Data Improvement Strategy
We improve real-user CrUX metrics by optimizing the actual user experience — not just Lighthouse lab scores. This includes real-user monitoring setup, performance budgets, and regression prevention.
Third-Party Script Management
We audit every third-party script for performance impact, implement facade patterns for heavy widgets, defer non-critical analytics, and set up script budgets to prevent future bloat.
Ongoing Score Monitoring
We implement automated PSI monitoring across all key pages, with alerts when scores drop below thresholds — catching regressions from deployments, CMS updates, or new third-party scripts.

How It Works
Multi-Page PSI Analysis
We run PageSpeed Insights against every key page template — homepage, product/service pages, blog posts, landing pages, and category pages. Each page gets a detailed breakdown of lab metrics, field data, and failed audits with estimated savings.
Audit Prioritization Matrix
We rank every failed audit by score impact (how many points it's worth), implementation effort, and regression risk. High-impact, low-risk fixes go first. We create a phased roadmap so you see score improvements throughout the engagement.
Systematic Optimization Sprint
1–3 WeeksOver 1–3 weeks, we implement all fixes across every page template: image optimization, JavaScript deferral, CSS critical-path extraction, font loading, server response tuning, and third-party script management. All changes are staged and tested before deployment.
Score Verification & Field Data Tracking
4–6 WeeksWe re-test all pages via PSI and confirm improved scores across both mobile and desktop. For field data (CrUX), we set up monitoring and track improvements over 4–6 weeks as real-user data reflects the optimizations.
Deployment & Regression Prevention
Once scores are verified, we deploy final changes and set up automated PSI monitoring. You receive complete documentation, performance budgets, and alerts for any score regressions from future deployments.
