Core Web Vitals Optimisation Services
If your site is slow, jittery or lagging, Google will punish you harder than your worst ex.
This page explains what Core Web Vitals actually mean, why your site keeps failing them, and what happens when someone competent fixes your LCP, CLS and INP without turning your website into a white, blank skeleton of “minimalist design”.
Why Your Core Web Vitals Are Failing
Most websites don’t fail CWV because they’re big.
They fail because they’re built badly.
Here’s what usually ruins your Core Web Vitals:
- Images the size of small planets
- Theme builders loading more scripts than a Marvel film
- Third party scripts slowing everything down
- Fonts that take longer to load than the actual page
- CLS (layout shift) caused by elements jumping around like they’re on caffeine
- LCP elements locked behind endless render-blocking resources
- Bloated JavaScript doing nothing useful
- Incorrect lazy loading
- Plugins fighting each other
- Hosting that belongs in a museum
- Developers who think “it loads fast on my laptop” is performance validation
And the cherry on top:
Half your site is pulling data from places it shouldn’t.
Google doesn’t care how pretty your site looks (Wikipedia, anyone?)
It cares how fast it actually loads for real users.
Who We’ve Helped With Core Web Vitals
We’ve improved CWV performance across ecommerce stores, service websites, SaaS platforms and high-traffic sites that were bleeding rankings because Google labelled them slow, unstable or unresponsive.
We fix technical issues that most agencies avoid because they don’t understand them.
Proof You Can Believe in
- LCP improvements from 4–6 seconds down to under 2
- CLS fixed from catastrophic to stable
- INP improved by eliminating bloated scripts
- Real user data (“field data”) improving within 30–60 days
- Search Console warnings cleared
- Sites gaining rankings because page experience stopped tanking performance
This is real, measurable performance work.
Not “install another caching plugin and hope”.
Is This Core Web Vitals Service Right For You?
It’s for you if:
- Your site is slow, laggy or flickering.
- Google Search Console keeps shouting at you.
- You want better rankings through better performance.
- Your developers have no idea what any of this means.
- You want to fix web performance properly, not patch it.
It’s not for you if:
- You want a magic button
- You think CWV is “just a speed issue”.
- You refuse to remove any scripts, plugins or third party junk.
- You think Google’s metrics “don’t matter”.
If you want a faster, cleaner, more stable website, this is the work that gets you there.
What a Proper CWV Optimisation Includes
Largest Contentful Paint (LCP) Fixes
Optimising images, reducing server response times, deferring render-blocking resources and prioritising the largest page elements.

Interaction to Next Paint (INP) Improvements
Reducing heavy JavaScript, improving input responsiveness and lightening scripts that delay user interaction.
Technical Clean-Up
Critical CSS, deferring non-critical CSS, removing unnecessary JavaScript files and compressing resources.
Performance Diagnostics
Using field data, CRuX data, Search Console reports and performance tools to measure what actual users experience.
Hosting + CDN Optimisation
Improving server performance, caching, compression and global delivery.
Ongoing Monitoring + Refinement
Core Web Vitals aren’t one-and-done. We track real user data over time.
The Hidden Issues Quietly Breaking Your Core Web Vitals
Most of your CWV problems come from things you didn’t even know existed:
- Third party scripts blocking the main thread
- Fonts that don’t load in time
- CSS shipped in bloated bundles
- Incorrect caching rules
- LCP images not labelled correctly
- “Lazy loading everything” when some things should load immediately
- JavaScript execution delays caused by cumulative code
- No priority hints for important resources
- CLS caused by ads, banners or sliders
- Page elements shifting because content loads out of order
- Field data worse than lab data, meaning real users suffer even if Lighthouse looks pretty
If your site feels unstable, Google knows it before you do.
Why Core Web Vitals Are Brutal
CWV hits harder because:
- It uses real user data (not your perfect internet connection).
- It measures how your site behaves, not how it looks.
- It exposes bad decisions your developer buried under plugins.
- It identifies bottlenecks you can’t see without tools.
- It updates every 28 days in Search Console, so problems linger.
You can’t fake a fast experience.
You have to build one.
