Digital development service

Website performance and Core Web Vitals optimisation

We find actual bottlenecks in images, fonts, CSS, JavaScript, plugins, caching, the database and server response.

When this service is useful

The problem determines the solution

A single laboratory score does not explain the complete problem. We review page types, real resources, mobile journeys and server behaviour.

Priority goes to changes with measurable impact rather than installing another optimisation plugin.

  • LCP, CLS or INP are below expectations
  • Mobile pages load noticeably slowly
  • Catalogue or administration queries are slow
  • Updates repeatedly degrade performance

What we can do

What this capability covers

The scope follows a short review of goals, current condition and constraints.

01

Resource audit

We measure images, fonts, CSS, JavaScript and third-party scripts.

02

Core Web Vitals

We identify LCP elements, CLS causes and long tasks affecting INP.

03

Images and fonts

We configure sizes, formats, lazy loading, preload and local delivery.

04

CSS and JavaScript

We reduce duplication, defer non-critical work and control dependencies.

05

Caching and CDN

We configure cache layers and Cloudflare with dynamic pages in mind.

06

Database and server

We examine slow queries, cron, PHP, object cache and response time.

How the work is organised

From assessment to a verified result

Each stage has a clear output and a practical completion criterion.

  1. 01

    Assessment and priorities

    We clarify the context, review the current state and identify critical dependencies.

  2. 02

    Solution architecture

    We define user flows, data, integrations and an implementation approach without unnecessary complexity.

  3. 03

    Development and validation

    We deliver in stages and test core flows, edge cases and error handling.

  4. 04

    Launch and growth

    We verify production, document what matters and agree on the next priority.

FAQ

Questions before starting

Is a caching plugin enough?

Not always. It cannot fix oversized images, heavy third parties, slow queries or poor architecture.

Which matters more: PageSpeed score or Core Web Vitals?

The score helps diagnosis, but field data, critical page types and actual user experience matter.

Can you optimise e-commerce?

Yes, with specific treatment for catalogues, filters, cart, checkout, personalisation and pages that cannot share the same cache.
