Website performance work helps you keep the visitors a slow site loses: we measure, fix and show the result in numbers.
Why website performance matters
A slow website loses out twice: visitors leave before it loads, and Google’s page experience signals, including Core Web Vitals, are among the many factors it considers when ranking pages. Speed alone will not put you at the top, but a slow site makes everything else harder.
What we do
Diagnostics
We measure the real metrics (LCP, INP, CLS) and find the actual causes: uncompressed images, excess code, a slow server or plugin conflicts.
Optimisation
We compress and convert images, set up caching, remove unnecessary scripts and optimise fonts and the database, focusing on what moves the numbers most.
A verifiable result
We measure before and after, so you see the result in numbers rather than promises, along with recommendations for keeping the site fast.
What we measure
The three core metrics are Google’s Core Web Vitals. LCP shows how quickly the largest visible element loads; Google rates 2.5 seconds or less as good. INP measures how quickly the page responds to clicks and taps (200 ms or less is good), and CLS measures whether content “jumps” while loading (0.1 or less is good). Google collects these figures from real visitors’ browsers, so there are no shortcuts: only genuine improvements move them. You can check your own numbers for free at PageSpeed Insights.
On top of these we measure the practical side: time to first byte (server speed), total page weight and request count. Mobile and desktop are checked separately, because pages usually load more slowly on phones, and for many sites that is where most visitors come from.
The most common causes of slow websites
The most common culprit is uncompressed images: photos of several megabytes sent at full size even to a small phone screen. Next comes plugin overload: each plugin adds its own scripts, and a year or two later the site is loading dozens of unnecessary files. Third is cheap or overloaded hosting, where the server responds slowly before anything even starts loading.
The good news is that all three can usually be fixed without rebuilding the site, and you can see the result in the same Google tools we used to measure the starting point.
How the optimisation project runs
We start with full diagnostics and a written plan with an estimate, showing which fixes bring the biggest jump. The work happens on a staging copy: images are compressed and converted to modern formats, caching is configured, unnecessary scripts are removed, and fonts and the database are optimised. Every change is measured separately, so we know what made the difference.
At the end you receive a before-and-after report, the list of completed work and recommendations for keeping the site fast. Under our maintenance plan speed is then monitored continuously, so new content or plugins do not quietly drag the site back to where it started.
What you can do yourself today
A few things are worth checking on your own. Images first: photos uploaded straight from a phone or a photographer often weigh several megabytes where a few hundred kilobytes would do. Then the plugin list: deactivate what you no longer use, because even idle plugins sometimes leave their scripts behind. Finally the hosting plan: if your site shares a server with hundreds of others, no amount of optimisation will make up for a slow first response.
These steps often bring a visible improvement, but the bigger gains come from making everything work together: the right image formats, a sensible loading order and clean code. That is the work we do, measured at every step and tested on a staging copy so that nothing that already works gets broken.
If a site is built on a very old foundation, patching it is sometimes less economical than rebuilding it. In that case we will tell you and offer a comparison with a new build, with clear numbers, so you can decide from facts rather than guesses.
Frequently asked questions
Do you optimise websites you didn’t build?
Yes, that is the usual case for speed work. We start with diagnostics and discuss the findings before any work.
How much faster will my site get?
It depends on the state of the site, and we do not promise a number before measuring. After diagnostics we tell you what to expect for your site specifically.
Will the improvement last?
Yes, if the site is looked after - new plugins and content slow it down again over time. Our maintenance plan from €80/month includes speed monitoring.
How often should website performance be checked?
At least once a quarter, and after every bigger change to the site: a new plugin, a design refresh or a large batch of new content. Google calculates its field metrics from 28 days of visitor data, so changes show up with a delay, and the earlier you notice a downward trend, the cheaper it is to reverse. If you are on our maintenance plan, we do this for you and tell you about any significant change.
Can optimisation break anything?
In theory yes - which is exactly why we work on a staging copy, where a mistake costs nothing. Aggressive caching tools, script merging or wrong image conversion can distort a design or stop forms - we have seen the results of such “optimisations” when site owners came to us after experimenting on their own.
Every step can be rolled back, and before moving changes to the live site we check all the key scenarios: form submissions, cart behaviour, mobile view and logins. The goal is a faster site that works just as reliably as before. We also leave you a short list of things to avoid, so the site stays fast.
