Mathew WatersPricing guidance
How much does performance optimisation cost?
Indicative NZ$ bands to help you budget. Final scope and freelancer rates are agreed directly with the freelancer.
Audit & small fixes
A focused audit plus one or more priority fixes (image optimisation, caching, minor server tweaks).
NZ$900–2,500
Site‑wide optimisation
Full site work improving Core Web Vitals, CDN and caching, database optimisations and theme/plugin refactor where required.
NZ$2,500–8,000
Re‑architecture and heavy scaling
Significant re‑engineering, hosting reconfiguration, autoscaling and monitoring for high‑traffic stores or web apps.
NZ$8,000–25,000+
What affects the price
- Platform and code quality (WordPress, Shopify, custom app) — fragile or legacy code raises effort.
- Hosting and infrastructure changes required (managed host vs cloud re‑architecture).
- Third‑party integrations and plugins that limit caching or require bespoke work.
- Scope of testing and monitoring (load testing, real‑user measurement, post‑deploy support).
Estimates are indicative, may exclude GST and ongoing software or platform fees, and final scope and rates are agreed directly with the freelancer. Request a tailored quote from applicants.
Frequently asked questions
Common questions before you hire.
Answers to the questions clients commonly ask before starting a brief.
Still deciding what you need?
Start with the outcome and the context you already have. A polished specification is not required.
How long will optimisation take?
Small audits and fixes can take a few days; site‑wide work typically takes 2–6 weeks depending on scope. Your chosen freelancer will give a clearer timeline in their application.
Will this improve our Google ranking?
Improved page speed and Core Web Vitals can help user experience and remove one barrier to ranking, but SEO outcomes also depend on content, links and competition.
Which platforms can specialists work on?
Freelancers work across WordPress, WooCommerce, Shopify, custom web apps and hosted platforms. Include platform details in your brief so applicants can confirm suitability.
How do I start and what happens next?
Create a short project brief on Unicorn Factory describing goals, traffic patterns and access. Relevant freelancers will apply, you review applications, and Unicorn Factory makes warm introductions.
How do I trust a freelancer’s claims about performance gains?
Ask for before/after metrics, sample reports, or references. A good brief requests measurable baselines (Lighthouse scores, Core Web Vitals, RUM) so improvements can be verified.
