ServicePerformance Optimisation
Web Application Performance Optimisation
Stop losing users and revenue to slow pages.
Slow pages usually have more than one cause, and the biggest is rarely where people start looking. We measure the whole path a request takes, from the browser through to the database, then fix what is costing you the most.
Common issues we see
Your app is slow and you're losing users or conversions because of it
Core Web Vitals are failing and hurting your search ranking
Pages feel fine in development but crawl under real load
You've optimised the frontend but the bottleneck is somewhere else
Performance regressed over time and nobody owns fixing it
Slow response times are starting to cost real revenue
What to expect
Every engagement runs the same way, so you know what happens next at every point.
- 1
Discovery call
Thirty minutes, free, no commitment. You tell us what you are trying to do and what is in the way. If we are not the right people for it, we say so on the call.
- 2
Baseline measurement
We measure what your application actually does today, on real pages and real journeys, so every later claim has a number behind it.
- 3
Findings ranked by impact
Everything we found, in the order it is costing you users and money. The quick wins are marked, so your team can take those straight away while we work on the rest.
- 4
Remediation
Hands-on fixes, largest impact first, each one measured rather than assumed. You see the number move as we go.
- 5
Proof and monitoring
The same measurements run again so the improvement is demonstrated, not claimed, and monitoring left in place so a regression is noticed by a machine rather than a customer.
What's included
- Core Web Vitals optimisation (LCP, INP, CLS)
- Bundle analysis, code splitting, and caching strategy
- API and database query analysis
- Rendering strategy review (SSR, SSG, ISR, client-side)
- Load testing and resilience review
- Prioritised remediation plan, or hands-on delivery
How we can work together
Performance Audit
Assessment plus a prioritised remediation plan
Targeted Optimisation
Hands-on fixes for the critical issues
End-to-end Programme
Full audit plus implementation, start to finish
Common questions
My frontend is already optimised. Can you still help?
Usually, yes. When the frontend is tuned and things are still slow, the bottleneck is normally further back: API design, database queries, rendering strategy, or caching. We audit the full stack and find the problem wherever it actually lives.
Will this improve my Core Web Vitals and SEO?
Core Web Vitals (LCP, INP, CLS) are a core part of the work, and improving them helps both user experience and search ranking. We measure before and after so the improvement is evidenced, not assumed.
Do you just advise, or actually fix it?
Both are available. Some clients want a prioritised plan their team can execute; others want us to do the hands-on remediation. The end-to-end option covers audit through to implementation.
How do you measure success?
Against real metrics: Core Web Vitals, load and response times, and where relevant, conversion or engagement. We agree what good looks like up front so the result is objective.
What does it cost?
Every engagement is fixed-scope and quoted after a short review of your application, so you know the cost before any work starts. It depends on the size of the application and how much you want us to fix versus report on.
