WordPress Website Speed Optimization Services
A faster website is easier to use, easier to find and cheaper to run ads to. We speed up WordPress sites for Dublin businesses by fixing the code, images, hosting and caching behind them, not just adding a plugin. Below are real PageSpeed Insights results for sites we built, tested on 11 November 2026, with the misses shown as well as the wins.
Real tests, real numbers.
Google PageSpeed Insights, run on 11 November 2026. Pick a site and a device. Scores move a little between runs, so treat them as a snapshot.
Green is 90-100, amber 50-89, red 0-49, as scored by Google. Lab results from PageSpeed Insights; Google had no real-user data for these sites.
Fast sites are easier to find and use.
Google measures loading, responsiveness and visual stability as Core Web Vitals, and they are part of how it judges page experience. Visitors judge you faster still.
Loading: LCP
How long the main content takes to appear. It's usually the biggest image or heading, and the most common thing we fix.
Responsiveness: TBT and INP
How quickly the page reacts when someone taps. Heavy scripts and plugins are the usual cause.
Stability: CLS
Whether things jump around while loading. Missing image sizes, late fonts and banners are the usual culprits.
Common website speed killers.
Unoptimised images
Huge photos served at full size to phones. Modern formats, correct sizes and lazy loading fix most of it.
Bloated themes and page builders
Heavy themes load code for features you don't use.
Too many plugins
Each one adds code and requests. We remove, replace or tame the ones that cost the most.
Weak hosting and no caching
A slow server, an old PHP version or no object cache slows everything before the page even starts.
Third-party scripts
Chat widgets, trackers, cookie banners and fonts can quietly add seconds.
A cluttered database
Revisions, transients and leftovers from old plugins slow queries over time.
Measure, fix, measure again.
We work from the test results, change one thing at a time and re-test, so you can see what each fix did.
- 01
Test and audit
PageSpeed Insights and GTmetrix on mobile and desktop, plus a review of your theme, plugins, hosting and scripts.
- 02
Fix the heavy things
Images, fonts, unused CSS and JavaScript, and plugins that cost more than they give.
- 03
Cache and serve
Page caching, object caching and a CDN, using tools such as LiteSpeed, Redis and Perfmatters where they suit your hosting.
- 04
Re-test and report
Before-and-after numbers in plain English, and what is still worth improving.
What we can promise, and what we can't.
We can find what's slowing your site and fix what's in our control. We can't promise a perfect 100: scores vary between runs, and chat widgets, cookie banners, big videos and slow hosting all cost points. Our own results above include amber scores, and we'd rather show them than hide them.
Irish business owners, in their own words.
Real Google reviews.
Michal designed and maintains a website for me and does a fantastic job. From start to finish it was a seamless process. Couldn't recommend more.
Digital Lab were a pleasure to deal with, very professional, conscientious and knowledgeable. I strongly recommend the company.
Google scores Performance from 0 to 100: 90-100 is green, 50-89 amber and below 50 red. Aim for green on mobile, but treat the score as a guide. Real loading speed, Core Web Vitals and a good experience matter more than chasing exactly 100.
No. We work on a staging copy or take a full backup first, change the front end and the server settings separately, and test your forms, shop and key pages before anything goes live.
Sometimes. A slow server response, no object caching or an old PHP version holds back even a well-built site. We check this first and tell you honestly whether hosting needs to change.
Yes. Both are common on the sites we optimise, and both need care: shops need carts and checkout left uncached, and page builders need their unused code trimmed.
Speed is one signal among many and it won't fix weak content on its own. A faster site does give visitors a better experience, which helps enquiries and conversions, and it removes a handicap for rankings.
No, and nobody honestly can. Scores vary between runs, and third-party scripts, cookie banners and large media all count. Our own results on this page include amber scores. We'll tell you what's realistic for your site before we start.
It depends on the site: its size, theme, plugins, hosting and what the audit finds. After a free speed check we send a fixed written quote, so you know the cost before any work starts.
A typical small-business site takes days to a couple of weeks, depending on how much needs fixing and how quickly we can get hosting access. Your quote includes a timeline.
No. We optimise existing WordPress sites as well as the ones we build ourselves.
