Stand Alone Service Type:
Give Your Clients Faster Sites and Passing Web Vitals Scores
Page speed refers to how quickly a webpage loads and becomes usable for visitors. Core Web Vitals are a set of performance metrics defined by Google that measure real user experience on a page. These metrics focus on loading speed, visual stability, and interactivity—specifically Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS).
Maintaining strong page speed and Core Web Vitals is important because slow or unstable pages frustrate users and increase bounce rates. Fast, stable pages improve user experience, increase engagement, and help search engines better evaluate site quality. Since Google uses these signals in ranking considerations, optimizing them can also improve search visibility and overall website performance.
White-Label Page Speed Audit with Fix Plan and Implementation
What This Service Includes
Core Web Vitals are a confirmed Google ranking factor — and most agency clients are failing them without knowing it. LCP too slow, CLS from layout-shifting images, INP delays from bloated JavaScript — these are the performance issues that suppress rankings regardless of how strong the content strategy is. We identify exactly what’s causing the problem on your client’s site, deliver a prioritised fix plan your developer can act on immediately, and optionally implement the fixes directly. Everything is white-labeled under your agency brand.
This service identifies exactly what’s slowing down your site and provides a prioritized implementation plan to fix performance bottlenecks. We can audit and recommend, or execute the fixes directly depending on your needs.
Order this for clients who:
- Have failing Core Web Vitals scores in Search Console field data
- Run e-commerce stores where slow product pages are contributing to poor conversion rates
- Have content-heavy sites with unoptimized images or video embeds causing CLS and LCP issues
- Are preparing for a major campaign, product launch, or seasonal peak and need performance validated first
- Have had performance issues flagged in a technical audit but lack the development resource to prioritize and fix them
What We Deliver For Your Client
Phase 1: Performance Auditing
Comprehensive Performance Analysis
- PageSpeed Insights testing (mobile + desktop)
- Lighthouse audit across key page templates
- Core Web Vitals field data review (real user metrics from Search Console)
- GTmetrix and WebPageTest analysis for detailed waterfall insights
- Performance profiling across different templates (homepage, product, blog, etc.)
Largest Contentful Paint (LCP)
- Identify which element is LCP on key templates
- Measure current LCP scores (goal: under 2.5 seconds)
- Diagnose causes: slow server response, render-blocking resources, slow resource load times
First Input Delay (FID) / Interaction to Next Paint (INP)
- Measure current interaction responsiveness
- Identify JavaScript blocking main thread
- Find long tasks causing delays
Cumulative Layout Shift (CLS)
- Identify elements causing unexpected layout shifts
- Measure impact of images without dimensions, web fonts, dynamic content
- Find third-party embeds causing shifts
Phase 2: Prioritized Fix Recommendations
We don’t hand you a 100-item issue list your client can’t act on. Every recommendation is prioritized by impact on Core Web Vitals scores, implementation difficulty, and expected ROI — so your developer knows exactly where to start and your client understands what they’re getting.
- Impact on Core Web Vitals
- Implementation difficulty
- Expected ROI
Typical Recommendations:
Image Optimization
- Compress and resize oversized images
- Convert to modern formats (WebP, AVIF)
- Implement responsive images with srcset
- Lazy load below-the-fold images
- Set explicit width/height to prevent CLS
JavaScript & CSS Optimization
- Minify and compress CSS and JavaScript
- Defer non-critical JavaScript
- Remove unused CSS and JavaScript
- Inline critical CSS for above-the-fold content
- Optimize third-party script loading
Server & Hosting Improvements
- Reduce server response time (TTFB)
- Enable compression (gzip, Brotli)
- Optimize database queries causing slowdowns
- Consider CDN implementation
- Upgrade hosting if server limitations exist
Caching Configuration
- Browser caching setup for static assets
- Server-side caching implementation
- Cache-control header optimization
Font Optimization
- Optimize web font loading (font-display: swap)
- Subset fonts to include only used characters
- Preload critical fonts
- Consider system font alternatives
Third-Party Script Management
- Audit performance impact of all third-party scripts
- Lazy load non-critical scripts (analytics, chat widgets, social media embeds)
- Remove or replace heavy third-party dependencies
Phase 3: Implementation (Optional)
Recommendation-Only:
We deliver developer-ready specifications and a prioritised fix plan for your client's development team — white-labeled and ready to hand over.
Collaborative:
We work alongside your client's developers, reviewing code changes and validating each fix as it goes live.
Full Implementation:
For WordPress, Shopify, and other accessible platforms we can implement fixes directly — all changes documented in a white-labeled report for client sign-off.
Phase 4: Testing & Validation
Post-Implementation Validation
- Re-test with PageSpeed Insights and Lighthouse
- Confirm Core Web Vitals improvements in field data
- Compare before/after performance metrics
- Validate no negative side effects (broken functionality, visual issues)
Ongoing Monitoring Setup
- Set up automated performance monitoring
- Configure alerts for performance degradation
- Establish baseline for future comparison

Who Needs This Service?
You Should Book This If:
- Order this for clients who: are failing Core Web Vitals thresholds in Search Console field data
- Have LCP scores above 2.5 seconds on key landing pages
- Show CLS issues from images without dimensions or layout-shifting elements
- Are on a platform like WordPress with plugin bloat slowing render times
- Have never had a performance audit and don’t know where the bottlenecks are
This May Not Be Necessary If:
- The client already passes Core Web Vitals on all key templates
- A comprehensive performance audit was completed in the last 6 months
FAQs
Common Questions
Core Web Vitals are a confirmed ranking factor, especially on mobile. While not the strongest factor, failing CWV can hold you back, and passing gives you an edge—especially against competitors with poor performance.
Permanent if properly maintained. However, adding new features, plugins, or content can degrade performance over time. We recommend quarterly performance checks.
We can't guarantee specific scores because platform limitations, hosting constraints, and third-party dependencies impact what's achievable. We focus on Core Web Vitals thresholds and real-world improvements.
Sometimes. If your hosting has fundamental limitations (slow server response times, poor caching), we'll recommend upgrades or alternatives.
We work with all major platforms. Some platforms have more limitations than others, but there are almost always meaningful improvements possible.
