Performance Audit · Derry
Performance Audit in Derry
A performance audit for Derry organisations based on what your visitors experience rather than what a test tool reports. A laboratory score measured over a fast connection from a data centre says very little about someone loading a product page on a phone with three bars of signal, which is the visit that pays for the site.
Why this comes up
The problem
The score in the testing tool is respectable and the checkout still takes eleven seconds on a real phone.
What you get
What we deliver
- Field data gathered from actual visitors, segmented by device and connection
- The slowest revenue-carrying journeys identified rather than the slowest pages
- Third-party scripts measured individually, since each one has an owner and a cost
- Server response and caching examined where the delay begins before rendering
- Images and fonts assessed, as these remain the largest avoidable weight
- Recommendations ordered by seconds saved on the journeys that generate income

Performance Audit in Derry — common questions
- Why prefer field data to a test score?
- Because it reflects the visitors you have. Real user measurement captures the phone on a poor connection and the laptop with fourteen extensions, and those visits are both slower and more numerous than any synthetic test configuration will suggest.
- How should third-party scripts be handled?
- Measured one at a time, with somebody accountable for each. Marketing tags, chat widgets and testing tools accumulate over years, and presenting the cost of each in seconds tends to produce decisions that a general recommendation to reduce scripts never does.
- Does speed genuinely affect revenue?
- On transactional sites, measurably. Abandonment rises with delay in a way that is visible in your own analytics once you segment by load time, and using your figures rather than published benchmarks makes the case far more effectively internally.
- What comes out of the audit?
- A short ordered list with expected gains. Not every improvement is worth the engineering time, so pairing each recommendation with the seconds it saves and the effort it takes lets a team stop at the point where further work costs more than it returns — which most performance reports never acknowledge exists.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
