Performance & Core Web Vitals
I get your Core Web Vitals into the green by fixing the site itself: images, fonts and scripts, rather than adding a caching plugin on top. Speed is one of the few changes that helps search ranking, conversion and hosting cost at once.
What’s included
A plain list of what the project involves, so you can see where the time and money go.
Lab and field data together. Lab data shows what’s slow; field data shows what your visitors experience on their own devices.
The hero element identified, prioritised, sized correctly and never hidden behind an animation waiting to fade in.
Dimensions on every image, space reserved for anything injected late, and fonts that swap without moving the page.
Long tasks split up, listeners made passive and work moved off the main thread, so taps respond straight away.
Modern formats, correct sizes, lazy loading below the fold and fonts that don’t block the first paint.
Re-measured once real traffic arrives, because staging numbers aren’t the ones Google uses.
Process
A baseline from PageSpeed Insights, Lighthouse and Chrome UX field data, mobile first.
What is causing each metric to fail. Usually it comes down to three or four causes.
Highest impact first. Most of the gain typically comes from images, fonts and blocking scripts.
Re-measure, hand over the numbers and note what will slow the site down again if content is added carelessly.
The difference
| The usual | This way | |
|---|---|---|
| Approach | Cache the slow page | Make the page not slow |
| Images | Compressed in place | Right size, right format |
| Fonts | Left as-is | Subset, preloaded, swapped |
| Scripts | Minified | Removed or deferred |
| Result | Lab score moves | Field data moves |
Questions
No, and nobody else can either. The score depends on the device, the network and the third-party scripts you need. What I can commit to is passing Core Web Vitals and a measurable, documented improvement.
It affects how many people stay long enough to buy, and it’s a confirmed ranking signal. It’s not the only thing that matters, but it’s one of the few you fully control.
No. Builders add weight, but most of the damage comes from images, fonts and plugins. A builder site can pass Core Web Vitals when it’s built with restraint, and this one does.
I measure what each one costs and show you the trade-off. Some can be deferred or self-hosted, some are worth their cost, and some turn out to be forgotten and can simply go.
The build will. What tends to undo them is content added later, like a 4 MB image dropped into a page. The handover covers exactly that.
