Sales page speed sprint
E-commerce brand (funnel builder)
A live sales page took 11.6s to show its main content. Ads were paying for visitors who left before it loaded.
Speed & Core Web Vitals fix
Make your slow site fast, without redesigning it.
Slow pages cost you twice: visitors leave before they see your offer, and Google ranks you lower when Core Web Vitals fail.
I find what’s actually slowing your page down and fix it at the source. On one live sales page, LCP went from 11.6s to 2.2s and Lighthouse from 65 to 97, with the same design.
Who this is for
- Sales pages and funnels paying for ad traffic
- Next.js or React sites failing Core Web Vitals in Search Console
- WordPress sites slowed down by themes and plugins
- E-commerce product and landing pages
What’s included
- Lighthouse and field-data audit (mobile and desktop)
- LCP fixes: image formats, sizing, preloading and priority
- CLS fixes: reserved space for images, embeds, fonts and banners
- INP fixes: deferring third-party scripts and heavy JavaScript
- Font loading and render-blocking resources cleaned up
- Before/after report with screenshots and scores
Process
How we’ll work together
Fixed scope and price before we start. A short update every working day.
- Step 1
Measure
I record baseline scores and find the LCP element, layout shifts and slow interactions on real devices.
- Step 2
Prioritise
You get a short list of fixes ranked by impact, so the biggest wins come first.
- Step 3
Fix
I apply the fixes on a staging copy or a branch, then on your live site once you approve.
- Step 4
Report
Before/after scores and what was changed, so you can keep the site fast going forward.

FAQ
Questions about this service
Do you need access to my code?
For Next.js/React sites, repository access is best. For WordPress or funnel builders, admin access to the page and its scripts is enough.
Will the design change?
No. Speed fixes are about how the page loads, not how it looks.
Can you guarantee a 90+ score?
I can’t guarantee a number when third-party scripts you need stay on the page, but I’ll tell you upfront what’s realistic after the audit, before you pay for fixes.
