Make it fast, and keep it fast
A slow site costs you twice. Visitors leave before it loads, and Google quietly ranks you below the competitor that fixed theirs. We do the technical work that moves your real-user Core Web Vitals into the green, then leave you a setup that stays fast.

- A faster site on the devices and connections your visitors use
- A before-and-after report you can show your team or your client
We fix what slows real visitors
A green Lighthouse score in a lab means little if real visitors still wait. We work from field data, pinpoint what slows the page for real users, and fix it at the source.
- Caching set up properly: page, object and browser caching with sane rules
- Images converted to modern formats, sized correctly and lazy-loaded
- Render-blocking CSS and JavaScript deferred or removed
The heavy hitters, handled
Most of the slowdown on a modern site comes from a handful of things: a bloated theme, three analytics libraries, an unoptimised hero image, a consent tool that runs on first tap. We go after those.
- A CDN configured so assets load from near your visitors
- Third-party scripts audited, deferred, or dropped
- The largest contentful element preloaded and prioritised
Proof, and a plan to stay fast
You get a report with the numbers before and after, from field data and lab tests, plus a short list of what to avoid so the site does not slide back in six months.
- Before-and-after Core Web Vitals from CrUX and Lighthouse
- A plain-language summary of what was changed and why
- A short 'do not do this' list for whoever edits the site
What's included
Everything in the box, on every plan
- Full speed audit. Field data, lab tests and a waterfall analysis to find what is slow.
- Caching & CDN. Page, object and browser caching plus a CDN, configured and tested.
- Image optimisation. Every image converted, resized, compressed and lazy-loaded.
- Script & CSS cleanup. Render-blocking resources deferred; unused code and dead plugins removed.
- Database optimisation. Revisions, transients and bloat cleared; tables optimised.
- Report & follow-up. A before-and-after report and a free re-check one month later.
How it works
Most sites are done in 3 to 6 business days. Field data (the numbers Google ranks on) takes up to 28 days to catch up, so the follow-up check confirms the result.
Audit
We pull your field data, run lab tests, and map exactly what is slowing the key pages for real visitors.
Optimise
Caching, images, scripts, CDN and database, in priority order, on a staging copy where possible.
Verify
We re-test against the same pages and devices and confirm the field metrics are moving the right way.
Hand over
You get the report, the summary, and the short list of things to avoid so it stays fast.

Frequently asked questions
How fast will I see results?
Lab scores improve immediately. The field data Google ranks on updates over about 28 days as real visits accumulate, which is why a follow-up check is built into every plan.
Will this change how my site looks?
No. Speed work is under the hood: caching, image formats, script loading, database. The design and content stay exactly as they are.
Can you optimise a large site or a store?
Yes. Large sites and stores are what the Advanced plan is for. Store checkout and cart performance get specific attention.
What if my hosting is the problem?
We will tell you plainly if it is. Sometimes the highest-value fix is a host move, and we will recommend one and help with the migration rather than paper over slow servers.
Do I need this again later?
Not if the site is maintained. Speed slides back when plugins pile up and images go in unoptimised. A maintenance plan keeps it in check; otherwise budget for a re-check every year or two.
