Optimization Services

A faster website. A checkout that still works.

WordPress speed optimization services diagnose and fix server, database, and front-end problems that slow your website down. WPservice.pro combines manual optimization, Core Web Vitals analysis, and functional testing — with a clear report of what changed.

Send your URL first. We’ll identify the likely bottlenecks and recommend a suitable scope.

Is this for you?

Built for websites that have work to do

Especially useful when you already have a caching plugin, but the website still feels slow.

01

WooCommerce stores

Product pages, filters, variations, cart fragments, customer sessions, and checkout all need different treatment. We review caching exclusions and test the buying journey after CSS or JavaScript changes.

02

Elementor & custom themes

Heavy widgets, nested layouts, sliders, theme assets, and font loading can slow down the first screen. We trace what the template loads and agree on any change that affects its appearance.

03

Business sites & agencies

For lead-generation sites, content publishers, and agency client websites with slow pages or disappointing mobile scores. Key landing pages, forms, menus, and tracking remain part of the brief.

The technical work

What we diagnose and optimize

01

Server, cache & CDN

Check cached and uncached response times, cache hits, expiry, hosting limits, and CDN behaviour. Review page caching and object caching separately. Logged-in pages and checkout need attention even when the homepage is cached.

02

Database & PHP

Review autoloaded options, unnecessary stored data, heavy plugins, and expensive server-side work. Database cleanup is manual and evidence-led; active data is not deleted simply because a table is large. Deeper database work is included in Standard and Pro.

03

Images & the first screen

Check oversized files, image dimensions, responsive sources, compression, and WebP or AVIF delivery. Prioritize the actual LCP image and correct lazy loading so the first screen is not kept waiting.

04

Fonts & layout stability

Review font families, weights, formats, and delivery. Remove unnecessary requests, use appropriate preloading, and investigate layout shifts caused by fonts, missing dimensions, banners, and late-loading content.

05

CSS & JavaScript

Trace render-blocking files, unused assets, and main-thread work. Configure minification, deferred or delayed scripts, unused CSS removal, and page-level unloading where suitable. Test exclusions against the features your visitors use.

06

Third-party services

Review analytics, advertising tags, consent tools, chat, maps, video embeds, and external APIs. Reduce avoidable loading work while preserving agreed tracking and consent behaviour. Any feature or measurement trade-off is discussed first.

The analysis sets the priorities. The agreed plan determines how many templates and issues we can address; a large store may need a custom scope.

How the work happens

A measured process, from URL to handover

01

Assess & agree

Send your URL and the pages or features that matter most. We review the symptoms, agree on scope, identify constraints, and set realistic targets before work starts.

02

Back up & establish a baseline

Confirm a current files-and-database backup and a rollback route. Record baseline tests on agreed pages. Use staging for higher-risk changes where available; plan production checks around live activity.

03

Optimize & test

Fix the biggest bottlenecks first, then retest. Check mobile and desktop layouts, navigation, forms, consent and agreed tracking. For stores, test product selection, cart updates, and the agreed checkout flow.

04

Report & hand over

Repeat tests, document changes and exclusions, and explain anything that remains limited by hosting or third parties. Handover includes recommendations and the support period attached to your plan.

How before-and-after testing is compared

Compare the same URLs and device profiles with consistent tool settings. Record test dates, cache/CDN state, and relevant configuration changes. Repeat lab tests — typically at least three runs per profile — and compare the median, while checking unusual outliers. Field data is reviewed separately where available.

The handover

What you receive

01

Implemented improvements

The agreed optimization work, with functioning settings and page-specific exclusions. Any approved code changes are documented so another developer can understand them.

02

Before-and-after report

Comparable mobile and desktop results for the agreed pages, test context, a list of changes, and an explanation of remaining bottlenecks.

03

Practical next steps

Clear recommendations for hosting, heavy plugins, content, or third-party services where further gains need a separate decision.

04

Support for the work

If an optimization change causes a problem, we correct it during the plan’s support period. Basic includes 2 weeks, Standard 1 month, and Pro 2 months.

PageSpeed Insights performance scores published in WP Rocket’s WPservice.pro case study, last updated 28 November 2024. These are selected client snapshots supplied for the article; exact run dates and complete test conditions are not listed. They are not controlled tests of WP Rocket alone.

Premium plugins included

Good tools. Carefully configured.

WP Rocket & Perfmatters

Included where they suit the website and agreed scope. We configure the features your stack needs, avoid overlapping optimization settings, and document important exclusions.

What a plugin cannot fix

A cache cannot remove every hosting limit, rewrite an expensive database query, or make a slow external API respond faster. Delay settings also need care: an improved score means little if a form stops working.

Already using FlyingPress, LiteSpeed Cache, or host-level caching? We assess the existing setup first. A plugin replacement is a technical decision, not a requirement of the service.

Core Web Vitals

Realistic targets. No 100/100 promise.

LCP ≤ 2.5 seconds

The main content should appear promptly.

INP ≤ 200 ms

Interactions should respond quickly.

CLS ≤ 0.1

The layout should stay stable as content loads.

These are Google’s “good” thresholds, assessed at the 75th percentile of visits. They are reference targets, not a guarantee for every website. Your hosting, templates, features, traffic, and third-party services affect what is achievable.

A Lighthouse score is a lab measurement. Google’s Chrome UX Report uses a rolling 28-day window of real visits, where sufficient data exists, so field improvements take time to appear. Total Blocking Time helps diagnose lab performance; it is not a substitute for field INP.

We do not promise a perfect score, a specific Google ranking, or a sales increase. The aim is measurable improvement while preserving agreed design and functionality. Google’s Core Web Vitals guidance ↗

The person behind the work

Work with Dalibor Druzinec

I run WPservice.pro from Zagreb, Croatia, through my business Ermada. I’ve worked professionally with WordPress since 2019, focusing on speed optimization, maintenance, and technical SEO.

My background is in civil engineering. These days, the structures I investigate are databases, templates, and the occasionally overambitious JavaScript bundle.

More about Dalibor ↗   View Upwork profile ↗

I also build WordPress performance tools

Speed Analyzer helps diagnose performance issues and produce reports. Code Unloader handles asset unloading. AI Assets Scanner identifies page-level CSS and JavaScript unloading opportunities.

That development work informs the service. Tools support the diagnosis; the website’s behaviour decides which changes stay.

If you need expert help, WPservice is at the top of the game when it comes to WordPress speed optimization.

Our WordPress site experienced a remarkable boost in page speed thanks to Dalibor’s code optimizations. He enhanced performance without compromising features, showcasing his considerable expertise.

Pin Adventure team

Dalibor was professional and delivered solid results. After a free initial assessment where he showed already great knowledge, he optimized the main pains related to my website core vitals in a day.

Andrea Rapanaro

My site was at 40% page speed score and we got it up to 96% after some optimizations and then some code change recommendations. Very happy with the results.

Jason Goldberg

Within just 3 days, the website transformed in a way that still leaves me amazed. Dalibor is exceptionally professional, dedicated, and communicative.

FAQ

Questions before we start

Do you need access before the free analysis?

No. Send the public website URL and a brief description of the problem first. WordPress or hosting access is requested only when the agreed work needs it.

What access will the optimization need?

Usually a temporary WordPress administrator account; hosting, SFTP, or CDN access may also be needed for the agreed changes. Use separate temporary accounts where possible, share credentials securely, and revoke access after handover when no longer needed.

Will you change the design or remove features?

Preserving the agreed design and functionality is the starting point. If a heavy slider, widget, plugin, or external service limits further improvement, we explain the trade-off before changing or removing it.

Will my website stay online?

The work is planned around keeping the website usable. We confirm backups and rollback options, use staging for higher-risk work where available, and agree on any maintenance window. A store’s live orders and customer data must be preserved.

How long does the work take?

Basic allows up to one day of work, Standard up to three, and Pro up to five. These are work limits, not guaranteed elapsed delivery times. Scheduling, access, approvals, and any third-party investigation affect completion.

Can you fix a slow WordPress dashboard too?

We can investigate it within the agreed scope. Page caching mainly helps public pages; a slow dashboard can involve plugins, queries, autoloaded data, scheduled jobs, or hosting resources and needs a separate diagnosis.

Will the improvement last?

The changes stay in place, but future plugin updates, new content, tracking tags, or hosting changes can affect performance. Your report explains what to watch; ongoing maintenance is a separate service.

Do you guarantee rankings or more conversions?

No. Faster, more stable pages can improve the visitor experience, but rankings and sales depend on much more than speed. We report technical results and explain their limits.
