Website Speed Optimization
Deep-dive performance engineering: Core Web Vitals, LCP, INP, image and font pipelines, caching, edge delivery and third-party script surgery.
"Every 100ms is worth real revenue."
Start a projectSite speed is the closest thing digital marketing has to compound interest. Google Discover, Search rankings, paid-media Quality Score, conversion rate and email deliverability all pull from the same underlying performance signal.
PrimeOak's speed audits treat performance as a systems problem — hosting, images, fonts, JS payload, third-party scripts, caching strategy — and fix them in priority order. Most sites see LCP cut in half within four weeks.
01 — Business Problems We Fix
Where growth actually breaks.
Core Web Vitals are red — SEO is bleeding rankings.
Third-party scripts (chat, ads, analytics) drag every page.
Fast on desktop, painful on 4G — mobile CVR suffers.
02 — What You Get
Everything you need, under one roof.
Full performance audit report
Green Core Web Vitals across every template.
Prioritised fix roadmap
2-4x faster time-to-interactive on mid-range Android.
Implemented optimisations
Restored SEO signals from performance and UX.
Post-fix measurement report
Higher paid-traffic CVR from faster landing pages.

Optimize
Ship the fixes — images, fonts, caching, JS.
04
Verify
Re-measure with CrUX + Lighthouse over 4 weeks.
Where speed actually leaks
The usual suspects: unoptimised hero images, blocking third-party scripts (tag manager, chat widgets, analytics), oversized fonts, hydration cost from bloated React trees, uncached API responses, and hosting on the wrong region.
We audit each of these against real 4G devices in your target geography — not just Lighthouse on a fast US laptop.
Fixes that stick
Every optimisation is documented so future changes don't regress. We add automated performance budgets to your CI pipeline where possible, so a slow image or a new marketing pixel gets caught before it ships.
Speed isn't a one-time project — but done right, the ongoing cost of keeping it fast is small.
04 — FAQ
Questions, answered.
How much speed can we realistically gain?+
Most sites move from 30–60 Lighthouse to 90+ with disciplined engineering.
Do we need to migrate frameworks?+
Usually no — 80% of gains come from images, fonts, caching and script hygiene.
How much faster can you make our site?+
Depends on the starting point. Most WordPress sites we audit go from LCP 4–6s to under 2s. Modern React sites we can typically shave 30–50%.
Do we need to rebuild the site?+
Usually no. Full rebuilds are only recommended when the architecture (plugin sprawl, wrong stack) is the actual bottleneck.
