spectrumled.pl website review

49 files are served with short cache lifetimes, so returning visitors download them again (5.8 MB).

10 images could be 3.9 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.4 s faster on a phone.

17 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.4 s.

About 218 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.2 s faster on a phone.

Your mobile performance score is 62 (desktop: 74). Pages that score under 90 lose visitors before the first paint.

Google Tag Manager costs a phone 383 ms of main-thread work and 496 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.

8 third-party services load with your homepage (Google Tag Manager, JSDelivr CDN and Cookie-Script.com and others), adding 948 KiB and 490 ms of main-thread time.

About 32 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

4 long tasks block the main thread while loading, the longest for 145 ms. During a long task the page ignores taps.

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

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.

Polyfills for old browsers add 5 KiB JavaScript that modern phones do not need.

3 KiB could be saved by minifying JavaScript.

2 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.

Your largest element takes 13.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “1 of 2”.

The page becomes fully interactive after 18.7 s. Good is under 3.8 s.

Visually, the page fills in at 6.6 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.2 s on a phone. Good is under 1.8 s.

Real visitors wait 2.9 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 1.2 s for your server to start answering (75th percentile). Good is under 800 ms.

5 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' tap response (inp) went from 95 ms to 102 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 1.8 s to 2.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 14.0 MB in 82 requests on a phone: images 11.4 MB (38), media 1.6 MB (2) and scripts 579 KiB (15). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 3.98 g of CO₂e: 477.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 tap target is too small or too close together to hit reliably with a finger.

All page content should be contained by landmarks: 26 elements on the page fail this check, rated moderate by axe-core.

13 visible links have no text or label, so screen readers cannot say where they go.

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

ARIA role should be appropriate for the element: 2 elements on the page fail this check, rated minor by axe-core.

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

Your title is 66 characters, so Google will cut it off around 60: “Oświetlenie LED, żarówki i lampy LED | Spectrum LED | Spectrum LED”.

Your meta description is 201 characters; Google truncates after about 160, so the end of your pitch is cut.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

There is no robots.txt at spectrumled.pl/robots.txt, the first file search crawlers ask for.

1 link has no real href, so search engines can't follow it.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 147 pages on spectrumled.pl and 14 external pages.

There is no https://spectrumled.pl/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://spectrumled.pl/spectrumled-katalog-oswietlenia-2026 has no <title>, so Google invents the link text in results.

/, https://spectrumled.pl/pl/program-bony-eksportowe, https://spectrumled.pl/pl/produkty, https://spectrumled.pl/pl/nowosci-produktowe, https://spectrumled.pl/pl/o-firmie and https://spectrumled.pl/pl/aktualnosci and 5 others all use the title “Oświetlenie LED, żarówki i lampy LED | Spectrum LED | Spectrum LED”. Search engines can't tell which page to show for a search, so each competes with the others.

https://spectrumled.pl/spectrumled-katalog-oswietlenia-2026 has no meta description, so Google writes the search snippet from whatever text it finds.

https://spectrumled.pl/pl/program-bony-eksportowe, https://spectrumled.pl/pl/produkty, https://spectrumled.pl/pl/nowosci-produktowe, https://spectrumled.pl/pl/o-firmie, https://spectrumled.pl/pl/aktualnosci and https://spectrumled.pl/pl/showroom and 5 others use the same meta description. A description written for each page earns more clicks.

https://spectrumled.pl/pl/program-bony-eksportowe, https://spectrumled.pl/spectrumled-katalog-oswietlenia-2026, https://spectrumled.pl/pl/produkty, https://spectrumled.pl/pl/nowosci-produktowe, https://spectrumled.pl/pl/o-firmie and https://spectrumled.pl/pl/aktualnosci and 8 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 108 found) and read each the way a search engine does.

9 of 35 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust 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 532 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics and Google Tag Manager (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 1 cookie (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.
