Website speed optimization for slow sites and poor Core Web Vitals

A slow website loses visitors before they even see what you offer. We find out exactly what is slowing it down, explain the findings in plain words and carry out the fixes.

What Google measures and why it matters to you

Google assesses the user experience of a page with three measurements it calls Core Web Vitals. LCP (Largest Contentful Paint) shows how quickly the main content appears, usually the large image or the headline. INP (Interaction to Next Paint) shows how quickly the page responds when you tap a button or open a menu. CLS (Cumulative Layout Shift) measures how much the page jumps around while loading, for example when text moves because an image loaded above it.

The usual causes of a slow website are few and they repeat: heavy images that have not been compressed or are not in a modern format, too many plugins each loading their own files, cheap shared hosting that is slow to respond, and scripts that block the page from rendering, such as chat widgets, ad pixels and fonts that load first.

Our audit starts from real-user data where it exists, and from mobile measurements. We record what weighs down each key page and give you a written list of findings, ordered by impact, along with a fixed price for the fixes. Once we agree, we make the changes and measure again.

We do not promise a specific score or Google position, because both depend on factors outside the website as well. We do promise to find the real causes and show you, before and after, what changed.

Where speed is usually lost

These are the areas we check first, because that is where most problems are.

Heavy images

Photos at full resolution or in old formats. We compress them, convert them to WebP or AVIF and serve them at the right size.

Too many plugins

Every plugin loads its own files. We identify which ones weigh the site down and which can be removed or replaced.

Slow hosting

If the server is slow to respond, nothing else helps enough. We check response times and, if needed, suggest moving to our own managed servers.

Render-blocking scripts

Chat widgets, pixels, maps and fonts that load before the content. We defer them or load them only when needed.

Layout shifts

Images without dimensions and banners that appear suddenly cause poor CLS. We fix them so the page stays stable.

Before and after

Every fix comes with a new measurement, so you can see what changed instead of relying on promises.

How we work

From first call to live, in five steps

The same process whether it is a five-page website or a platform your whole company runs on. What changes is the depth of each step, not the order.

01
Discovery call
Thirty to sixty minutes on what you do, who your customers are and what the project has to achieve. We ask about the business problem first and the technology last. No charge, no commitment.
02
Proposal & fixed quote
A written document with the scope broken down line by line, the timeline, the price and what is explicitly not included. You know the full cost before you decide.
03
Design & structure
Wireframes and page structure first, then visual design. For applications, we map the data model and the workflow before writing a line of code — that is where projects are won or lost.
04
Development & review
We build in stages on a staging server you can access at any time. You review real screens as they are finished instead of waiting months for a reveal.
05
Launch & aftercare
Go-live, analytics and Search Console setup, training for your team, written documentation, and ongoing support. Most clients keep evolving their project with us for years.

Open it on a phone using mobile data rather than Wi-Fi. If the main content takes several seconds to appear or the page is slow to react to taps, there is probably a problem. The Core Web Vitals report in Google Search Console also shows which pages need improvement.

No, and it is wise to avoid anyone who does. The score also depends on third-party tools you may need, and Google rankings depend on many factors. What we commit to is fixing the causes we identify and showing you the measurements before and after.

Yes. Many of the speed problems we see are on WordPress and WooCommerce, usually because of plugins, heavy themes and hosting. We also audit custom websites and e-shops.

It depends on the size and platform of the website. After a short free call and a first look at your site, we give you a written quote with a fixed price.

Sometimes a site is so overloaded that fixing it costs almost as much as rebuilding. In that case we tell you honestly, with costs for both options, and you decide.
