sunwebgroup.com website review

10 images could be 1.8 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.6 s faster on a phone.

Your mobile performance score is 64 (desktop: 74). Pages that score under 90 lose visitors before the first paint.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 900 ms.

13 files are served with short cache lifetimes, so returning visitors download them again (91 KiB).

About 150 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

2 third-party services load with your homepage (Cookiebot and Azure Web Services), adding 4.2 MB and 96 ms of main-thread time.

Azure Web Services costs a phone 0 ms of main-thread work and 4.0 MB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

About 66 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Your largest element takes 8.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Visually, the page fills in at 7.8 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 8.3 s. Good is under 3.8 s.

The first text or image appears after 2.8 s on a phone. Good is under 1.8 s.

4 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 1.5 s to 1.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.7 MB in 60 requests on a phone: images 4.0 MB (42), scripts 617 KiB (13) and stylesheets 87 KiB (1). Under 2 MB keeps phones on slow connections fast.

sustainability-vertical-1-512x805.jpg weighs 624 KiB. On a phone connection a single image that size takes seconds.

13 images (3.8 MB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

14 images further down the page (3.7 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

2 images are downloaded at several times the size a phone draws them, for example IMG_2864-1024x681.png at 1,024 px wide, shown at 330 px. Resized copies would save about 42 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.34 g of CO₂e: 160.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Links must have discernible text: 17 elements on the page fail this check, rated serious by axe-core.

4 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

ARIA dialog and alertdialog nodes should have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

<html> element must have a valid value for the lang attribute: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 14 elements on the page fail this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

Alternative text of images should not be repeated as text: 5 elements on the page fail this check, rated minor by axe-core.

The page declares lang=“lang=”, which is not a usable language code, so screen readers and translation tools guess.

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

There is no <h1>, so neither visitors nor Google get a clear main headline.

The homepage links to 27 pages on sunwebgroup.com and 24 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

There is no https://www.sunwebgroup.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

https://www.sunwebgroup.com/feed has no <title>, so Google invents the link text in results.

https://www.sunwebgroup.com/our-brands, https://www.sunwebgroup.com/sustainability, https://www.sunwebgroup.com/newsroom, https://www.sunwebgroup.com/contact, https://www.sunwebgroup.com/newsroom/sunweb-group-appoints-jeroen-de-swart-as-new-ceo and https://www.sunwebgroup.com/newsroom/sunweb-group-appoints-alan-french-as-chief-product-technology-officer-cpto and 5 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.sunwebgroup.com/our-brands, https://www.sunwebgroup.com/sustainability, https://www.sunwebgroup.com/contact, https://www.sunwebgroup.com/sunweb-group-cookies-overview, https://www.sunwebgroup.com/cookie-policy and https://www.sunwebgroup.com/feed and 1 other have no <h1> headline, so visitors and search engines get no clear main topic.

https://www.sunwebgroup.com/our-brands has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 11 pages linked from your homepage and read each the way a search engine does.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 1,341 words of visible text.

Opening the homepage sets 1 cookie (measured from a US location before any click).

Loading the homepage contacts 3 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
