WordPress Speed Optimisation
A slow site loses visitors before they have even seen the content. WordPress speed optimisation at Penkov Studio starts with measurement, moves on to images, caching and unnecessary code, and ends with a fresh measurement so you can see the real difference.
Speed Optimisation
- WordPress
- WebP
- AVIF
- Lighthouse
- PageSpeed Insights
- Chrome DevTools
01
What you get
Before and after measurements
Lighthouse and PageSpeed Insights tests on your key pages before and after the changes.
WebP and AVIF images
Conversion to modern formats, correct dimensions and lazy loading where it makes sense.
Caching
Page and browser caching configured so it does not interfere with forms, carts or user accounts.
Less unused CSS and JavaScript
Removing or deferring code a page does not use, and cleaning out plugins you no longer need.
Database clean-up
Old revisions, transient data and leftovers from deleted plugins that slow down both the dashboard and the site.
02
Process
Measure
Tests on the home page and your most visited pages, on mobile and desktop.
Diagnose
Finding the biggest causes of slow loading: theme, plugins, images, hosting or third-party scripts.
Optimise
Changes are made in order of priority, tackling the issues with the biggest impact first.
Check functionality
Testing forms, menus, the cart and anything else that caching or code optimisation might affect.
Measure again
A comparison with the original results and a short summary of what was done.

Why it matters
Technology
- WordPress
- WebP
- AVIF
- Lighthouse
- PageSpeed Insights
- Chrome DevTools
A good fit for
- WordPress sites that load slowly on mobile
- Sites with plugins that have piled up over the years
- Sites with heavy images and video
- Online stores with slow category and product pages
- Page builder sites that have become bloated
Faster for your visitors
Pages open faster, especially on phones and slower mobile connections.
A measurable difference
Before and after results are recorded, so you know exactly what improved.
Nothing broken
Every change is checked, because a faster site with a broken form is no improvement.
Why WordPress sites slow down
There is rarely a single cause. A slow WordPress site is usually the result of things piling up: a theme packed with features you never use, plugins added for one job and then forgotten, images uploaded straight from a phone, and third-party scripts for chat, maps and analytics. Each one looks harmless on its own, but together they make the page heavy.
Images are the usual culprit
A photo uploaded at full size can weigh as much as all the other code on the page combined. Converting to WebP or AVIF, serving the right size for each screen and lazy loading images below the fold often deliver the biggest gain for the least effort.
Caching that does not break the site
Caching lets the server return a ready-made page instead of assembling it on every visit. It needs careful configuration, especially on sites with forms, an online store or user accounts. For stores, the details are covered under WooCommerce development.
Unused CSS and JavaScript
Page builders and plugins load their styles and scripts on every page, even where they are not used. Deferring or removing that code cuts the time the browser spends busy and makes the site feel more responsive.
Speed or Core Web Vitals?
This service focuses on making your WordPress site faster overall. If Search Console is flagging specific LCP, INP or CLS issues, take a look at the Core Web Vitals service, which targets exactly those metrics. If your site needs regular care so it does not slow down again, see website maintenance. Send us your site address through the project inquiry form.
FAQ
Frequently asked questions
Do you speed up sites you did not build?
Yes. The work covers images (WebP and AVIF), caching and unused CSS and JavaScript, with measurements before and after, whoever built the site.
Will you get a score of 100 in PageSpeed Insights?
No specific score is promised, because it depends on your theme, hosting and third-party services. The aim is genuinely faster loading, and you see the before and after results.
Could the problem be my hosting?
It can be. If the measurements show a slow server response, you will get a recommendation and, if you wish, the site can be migrated to more suitable hosting.
Will the site look different afterwards?
No. The optimisation is technical and leaves the design unchanged, unless we agree otherwise.
How long do the improvements last?
Until new heavy plugins, images or scripts are added. Regular maintenance helps keep the site from slowing down again.
