Performance optimisation for slow websites, unstable UX, and lost conversions

Slow websites quietly kill SEO, paid traffic efficiency, and checkout completion. I focus on measurable fixes to your highest-value pages, not vanity metrics that look good but change nothing.

Quick answer

Performance work should start on pages that generate leads or revenue, not isolated benchmark pages. Reduce script weight, optimize media, and verify conversion flow after each release batch.

If this issue is urgent (down pages, broken checkout, failed deploy, or lost leads), start with a free audit and I will prioritise first-fix actions.

Who this fits

Teams with growing traffic, poor mobile outcomes, and rising acquisition costs where website speed and stability are now commercial priorities.

Problems I am brought in to fix

  • -Users abandon sessions because pages feel slow, unstable, or visually jumpy on mobile.
  • -Third-party scripts and trackers are consuming rendering budget on conversion pages.
  • -Image and caching setup is inconsistent, creating unnecessary load delays and regressions.

What is included

  • Measurement plan: baseline traces, key URLs, and what “good” means for your business.
  • A prioritised fix list (quick wins vs structural work).
  • Re-test after deploy so improvements survive real traffic.

Technical notes

I focus on user-centric metrics (INP/LCP/CLS) and business outcomes, not chasing a perfect lab score on a page nobody visits.

How I usually run it

Step 1

Baseline the money pages

Home, top landing pages, PDP/collection templates, and checkout-adjacent routes.

Step 2

Reduce waste

Script budget, image pipeline, server response patterns, and template hotspots.

Step 3

Lock it in

Guardrails: budgets for new scripts, image rules, and a simple regression checklist.

Pricing mindset

Usually a fixed performance sprint after a short audit. If the stack is fundamentally wrong, I will recommend a rebuild slice instead of polishing debt.

Frequently asked

Can you guarantee a 90+ Lighthouse score?+
No honest engineer should. I guarantee a clear plan, measurable improvements on your priority URLs, and honest trade-offs when marketing tags fight speed.
Headless for speed?+
Only when maintenance and editorial needs justify it. Often the win is simpler.
Can you work with our analytics setup?+
Yes. I keep performance work tied to business pages and existing analytics so improvements are visible in both lab metrics and conversion behavior.
Do we need a full rebuild to fix speed?+
Not always. I usually start with highest-leverage fixes first. Rebuild is recommended only when architecture debt blocks meaningful gains.

You will get a no-obligation technical review with clear priority steps.
