One Service for Every Speed Score
Improve Your PageSpeed, Lighthouse, and GTmetrix Score
We fix the performance problems that move every score at once, so your site is genuinely fast for real users, not just green in a single test.
PageSpeed Insights, Lighthouse, GTmetrix, and Pingdom all measure the same thing from slightly different angles: how fast your pages load and respond. Chasing one number in isolation is how teams burn weeks and still fail in the field. We find the real causes, server response time, render-blocking CSS and JavaScript, oversized media, heavy third-party scripts, and failing Core Web Vitals, and fix them at the source. The result is a higher score in every tool and a site that feels fast to the people who actually use it. Whether you need to improve PageSpeed Insights score numbers, run GTmetrix optimization, do Lighthouse performance optimization, or reduce FCP time, the underlying work is the same.

Our Expertise
Work With a Page Speed Score Expert
Moving a PageSpeed, Lighthouse, or GTmetrix score is a code problem, not a plugin you install. Every engagement is run by a performance expert who profiles your site with both lab tools and real-user data, isolates exactly what is dragging each score down, and fixes it at the source.
Teams come to us when a generic speed plugin has stalled and they need the numbers to actually move. You get a metric-by-metric report, before and after results across every tool, and documentation of every change, not a black box. We hit 90+ scores and passing Core Web Vitals when clients implement our recommendations.

How the Tools Differ
One Score Is Never the Whole Picture
Each tool weighs things differently, so the same site can score 95 in one and 70 in another. We optimize for all of them together by fixing the underlying load, not by gaming any single metric.
PageSpeed Insights
Combines a Lighthouse lab test with real-user CrUX field data. The field data is what Google uses for ranking, and it is the part most quick-win fixes never touch.
Lighthouse
The lab engine inside PageSpeed Insights and Chrome DevTools. Great for diagnosing, but a perfect lab score still fails if real devices and networks tell a different story.
GTmetrix
Adds a letter grade and a request waterfall. Useful for spotting heavy assets and slow third parties, which we trace and trim.
Pingdom
Reports load time and a waterfall from chosen test locations. We use it to confirm gains hold across regions, not just one server.

Common Problems
Why Are Your Speed Scores Low?
Failing LCP (Largest Contentful Paint)
Your hero image, banner, or main content element takes over 2.5 seconds to render. Causes: unoptimized images, render-blocking CSS/JS, slow server response (TTFB), and font-display issues.
Guide: LCP Optimization Deep DiveFailing INP (Interaction to Next Paint)
User interactions (clicks, taps, key presses) feel sluggish — taking over 200ms to respond visually. Causes: long JavaScript tasks, heavy event handlers, third-party script blocking, and main-thread congestion.
Guide: INP Optimization Deep DiveFailing CLS (Cumulative Layout Shift)
Page content jumps around unexpectedly as elements load. Causes: images without dimensions, dynamic ad/content injection, web font FOUT/FOIT, and late-loading components.
Guide: CLS Optimization Deep DiveLab vs. Field Data Mismatch
Your PageSpeed Insights lab score looks green, but Google Search Console shows failing CWV. Real users on slower devices and connections experience your site differently than simulated tests.

How We Raise Your Score
We improve the underlying Lighthouse metrics that make up your score, including First Contentful Paint, Speed Index, Largest Contentful Paint, Total Blocking Time, and Cumulative Layout Shift. We work from real measurement to root cause, not from a generic checklist. Here is what raising your score actually involves:
Server Response and TTFB
We profile origin response times, tune hosting, caching, and database queries, and move slow work off the request path so the first byte arrives fast on every page.
Render Path and Critical CSS
We inline critical CSS, defer non-essential stylesheets, preload key fonts, and clear render-blocking resources so the page paints quickly instead of staring at a blank screen.
JavaScript and Main-Thread Work
We code-split, defer, and trim JavaScript, break up long tasks, and clean up heavy event handlers so interactions respond quickly and Total Blocking Time drops.
Image and Media Optimization
We convert to WebP and AVIF, generate responsive srcsets, set fetchpriority on the hero, lazy-load below-the-fold media, and cut page weight without hurting visual quality.
Third-Party Script Control
We audit every external script for cost, defer or facade what we can, replace what we cannot, and set budgets so analytics, chat, and ads stop silently dragging the score down.
Core Web Vitals Field Validation
We monitor LCP, INP, and CLS in CrUX and real-user data, then iterate until the 28-day field window confirms the lab gains are real for actual visitors.
The Data
What Happens When Your Score Goes Up
A higher score is not the goal in itself. It is a proxy for a faster site, and a faster site keeps visitors, ranks better, and converts more. The research is consistent across every study:

Our Process
How It Works
Full CWV Assessment
We analyze LCP, INP, and CLS across all page types using both lab tools (Lighthouse, WebPageTest) and field data (CrUX, Search Console). Every failing metric is traced to its root cause — not surface-level symptoms.
Root Cause Profiling
Each failing metric gets a dedicated root cause analysis. We profile JavaScript execution, trace render waterfalls, identify layout shift sources, and measure real-user impact. You receive a ranked report showing exactly what's failing and why.
Optimization Sprint
1–2 WeeksOver 1–2 weeks, we implement all fixes on staging: Critical CSS generation, image optimization, JavaScript deferral, layout shift prevention, third-party script management, and server-side improvements. Zero risk to your live site.
CrUX Field Verification
2–4 WeeksWe monitor real-user field data (CrUX) over 2–4 weeks, making iterative adjustments until LCP, INP, and CLS consistently pass in Google's 28-day rolling p75 window — the actual data Google uses for ranking.
Deployment & Documentation
Once validated in the field, all changes are deployed to production. You receive complete documentation of every change, a speed budget for future development, and a before/after performance report with projected SEO and revenue impact.

PageSpeed Insights & Lighthouse
Google's score-card for performance, weighted heavily toward Total Blocking Time and Largest Contentful Paint. We fix the underlying causes so both lab and field results move together.
GTmetrix Grades
GTmetrix combines Lighthouse with its own structure audits. We resolve render-blocking resources, oversized images, and inefficient cache policies that cost you grade points.
Pingdom & Real Users
Pingdom measures load time and asset count from real network locations. We trim payload, defer non-critical work, and tune delivery so the numbers match what users actually feel.
