Our Core Web Vitals audit uncovers the root causes of poor LCP, CLS, and INP scores, delivering targeted, code-level optimizations that improve page experience and search performance — with a guarantee behind it.
What could passing Core Web Vitals be worth?
A rough, directional estimate — not a guarantee — based on typical conversion and traffic impact from CWV fixes.

A slow, layout-shifting page isn't just a poor Core Web Vitals score — it's also a page that AI crawlers may time out attempting to render, and content that shifts after load can be mis-parsed by systems reading a snapshot mid-render. Stable, fast-rendering pages are a prerequisite for reliable AI citation, not just Google ranking.
WHAT WE OPTIMIZE
Image Optimization
Convert to WebP/AVIF, implement responsive images with srcset, and lazy-load below-the-fold images. The single biggest LCP improvement for most sites.
Render Blocking Fix
Eliminate render-blocking CSS and JavaScript. We inline critical CSS, defer non-essential scripts, and optimize resource hints for faster first paint.
Layout Shift Prevention
Set explicit dimensions on images, ads, and embeds. Reserve space for dynamically loaded content and optimize font-display to prevent visual jumps.
JavaScript Optimization
Break up long tasks, implement code splitting, and optimize event handlers. We reduce main-thread blocking so your site responds to user input instantly.
Font Loading Strategy
Implement font-display: swap, preload critical fonts, and use size-adjust to minimize CLS from font swaps. Text stays visible and stable throughout load.
Caching Architecture
Implement browser caching, CDN edge caching, and server-side caching strategies. We configure cache headers, purge strategies, and stale-while-revalidate patterns.
PROCESS
HOW WE DELIVER
A rigorous approach to fixing Core Web Vitals with guaranteed results.
MEASURE
We measure your current Core Web Vitals using CrUX data, Lighthouse, and Real User Monitoring. We establish baselines for LCP, CLS, and INP across your most important pages.
IDENTIFY
We perform code-level analysis to identify the exact causes of poor scores. Every render-blocking resource, layout shift source, and long task is documented with specific line references.
FIX
We implement targeted fixes for every identified issue. From image optimization and critical CSS inlining to JavaScript code splitting and cache configuration — each fix is deployed and verified.
VERIFY
We verify improvements with real-world data — not just synthetic tests. We set up ongoing monitoring, confirm Google Search Console shows "good" status, and ensure scores hold under real traffic.
TECH STACK BEHIND THE FIX
REAL ENGAGEMENTS, REAL OUTCOMES
Every number below is from a documented client engagement. Full breakdowns are on our case studies page.
BARK
Monthly subscription boxes for dogs. Technical SEO, Shopify app audit, product canonicalization, and Core Web Vitals optimization at catalog scale.
Photobook
Personalised photo printing and gifting platform. Product canonicalization, seasonal gift guides, and Core Web Vitals optimization across a large image-heavy catalog.
The Fabric Store
An image-heavy catalogue that couldn't load. We implemented progressive image loading and rebuilt the shopping experience for stability and speed.
DIRECT FEEDBACK FROM ENGAGEMENTS
"Search Console had shown 'Poor' for over a year. Two weeks after the fix, it flipped to 'Good' and stayed there."
"They found a font-loading issue causing our layout shift that three previous 'audits' completely missed."
"The guarantee made this an easy yes — and we didn't need it, the fix worked exactly as promised."
COMMON QUESTIONS
Core Web Vitals are Google's metrics for measuring real-world user experience: LCP (load speed), CLS (visual stability), and INP (interactivity). They're a confirmed ranking factor.
Sites with poor CWV scores rank lower in search results and lose users — 53% of mobile visitors abandon sites that take over 3 seconds to load. Fixing CWV improves both rankings and revenue.
Ranking FactorUser ExperienceWe guarantee your site will achieve "good" CWV status in Google Search Console after our fixes are implemented. If we can't get your site to pass, you get a full refund — no questions asked.
Our 98% pass rate means this is extremely rare. The 2% of cases where we can't help usually involve platform limitations beyond code-level fixes.
98% Pass RateFull Refund GuaranteeStandard CWV fixes are completed within 5 business days. We deliver a detailed analysis within 48 hours, implement fixes over 3 days, and verify results on day 5.
Complex sites with heavy JavaScript or custom platforms may require additional time. We'll always provide a clear timeline upfront before starting work.
5-Day Standard48hr AnalysisWe work with WordPress, Shopify, Next.js, custom HTML, React, Vue, and virtually any web platform. Some platforms have limitations (like hosted Shopify), but we find workarounds for most constraints.
During our initial assessment, we'll tell you honestly if your platform has inherent limitations and what results are achievable within those constraints.
All PlatformsHonest AssessmentNo. We test every fix in a staging environment before deploying to production. Visual regression testing and functional QA ensure your site looks and works exactly the same — just faster.
We also create backups before any changes and document every modification so you can roll back instantly if needed.
Staging FirstFull BackupIndirectly, yes. A page that's still shifting layout or hasn't finished rendering when a crawler visits can be mis-parsed — by Googlebot or an AI crawler. Stable, fast-rendering pages are a baseline requirement for reliable citation, not just ranking.
