trio-lighting.com website review

11 images could be 3.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.5 s faster on a phone.

14 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.0 s.

Your mobile performance score is 52 (desktop: 71). Pages that score under 90 lose visitors before the first paint.

23 files are served with short cache lifetimes, so returning visitors download them again (426 KiB).

About 68 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.

trio.lighting costs a phone 158 ms of main-thread work and 404 KiB 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.

1 third-party service load with your homepage (trio.lighting), adding 404 KiB and 158 ms of main-thread time.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

2 long tasks block the main thread while loading, the longest for 77 ms. During a long task the page ignores taps.

About 54 KiB of JavaScript is downloaded but never used on this page.

39 KiB could be saved by minifying JavaScript.

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

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

5 KiB could be saved by minifying CSS.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

For real visitors the layout shifts by 0.46 (75th percentile). Good is under 0.1.

The layout shifts by 0.529 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Visually, the page fills in at 8.9 s (Speed Index). Good is under 3.4 s.

Your largest element takes 4.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Our new 2027 catalogs are here”.

The page becomes fully interactive after 8.2 s. Good is under 3.8 s.

Real visitors wait 880 ms for your server to start answering (75th percentile). Good is under 800 ms.

The first text or image appears after 2.1 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 111 ms to 108 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 1.7 s to 1.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.6 MB in 104 requests on a phone: images 4.7 MB (33), scripts 354 KiB (38) and fonts 354 KiB (6). Under 2 MB keeps phones on slow connections fast.

Grossmann-Image-LWS2026.jpg weighs 1.4 MB. On a phone connection a single image that size takes seconds.

2 images are downloaded at several times the size a phone draws them, for example Grossmann-Image-LWS2026.jpg at 1,754 px wide, shown at 294 px. Resized copies would save about 1.1 MB.

2 images (1.8 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.

By the Sustainable Web Design model, a visit to your homepage emits about 1.60 g of CO₂e: 192.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 buttons have no accessible name, so screen readers announce just “button”.

Links must have discernible text: 4 elements on the page fail this check, rated serious by axe-core.

14 images have no alt text, which hurts accessibility and image search.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Headings should not be empty: 2 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h3 → h6, h3 → h6 and h3 → h6), which makes the page harder to scan with a screen reader.

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 14 characters: “TRIO – Website”. Between 30 and 65 characters leaves room to say what you do and for whom.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

The homepage links to 34 pages on trio-lighting.com and 46 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://www.trio-lighting.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.trio-lighting.com/statements and https://www.trio-lighting.com/guarantee have no <title>, so Google invents the link text in results.

https://www.trio-lighting.com/home and / all use the title “TRIO – Website”, and 1 other title repeat too. Search engines can't tell which page to show for a search, so each competes with the others.

/, https://www.trio-lighting.com/catalogues, https://www.trio-lighting.com/features, https://www.trio-lighting.com/localization, https://www.trio-lighting.com/company and https://www.trio-lighting.com/statements and 8 others have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 7 pages by a URL that isn't their canonical one, for example /, whose canonical is https://www.trio-lighting.com/home. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://www.trio-lighting.com/features, https://www.trio-lighting.com/localization, https://www.trio-lighting.com/category/news, https://www.trio-lighting.com/faq and https://www.trio-lighting.com/user-agreement have no <h1> headline, so visitors and search engines get no clear main topic.

https://www.trio-lighting.com/features 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 15 pages linked from your homepage (of 18 found) and read each the way a search engine does.

3 of 12 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

6 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 401 ()”.

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 phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

There is no form on the homepage, so every lead has to click through to another page first.

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 280 words of visible text.

Opening the homepage sets 4 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 1 host run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
