secretlab.eu website review

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 4.0 s.

About 902 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.5 s faster on a phone.

Your mobile performance score is 34. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 9.6 s on main-thread work while loading, 4.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Signyfyd, ZenDesk and Google Tag Manager and others), adding 1.8 MB and 1.7 s of main-thread time.

About 515 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 870 ms faster on a phone.

Signyfyd costs a phone 740 ms of main-thread work and 260 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.

11 images could be 540 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

ZenDesk costs a phone 331 ms of main-thread work and 477 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.

Google Tag Manager costs a phone 307 ms of main-thread work and 380 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.

20 long tasks block the main thread while loading, the longest for 321 ms. During a long task the page ignores taps.

The page has 2,179 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Klaviyo costs a phone 112 ms of main-thread work and 369 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.

23 files are served with short cache lifetimes, so returning visitors download them again (183 KiB).

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 31 KiB JavaScript that modern phones do not need.

9 KiB could be saved by minifying CSS.

6 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.

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 20.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Secretlab ATLAS”.

Visually, the page fills in at 17.5 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 35.3 s. Good is under 3.8 s.

Scripts block taps and scrolling for 1.7 s in total while the page loads. Good is under 200 ms.

Real visitors wait 3.3 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 161 ms to 203 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.8 s to 4.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.3 s (75th percentile). Good is under 1.8 s.

The layout shifts by 0.11 while loading, so content jumps under the reader's thumb. Good is under 0.1.

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

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

Your homepage downloads 45.8 MB in 356 requests on a phone: media 38.9 MB (5), scripts 3.3 MB (127) and images 1.7 MB (35). Under 2 MB keeps phones on slow connections fast.

features-magnus-pro-home-splash-poster-mobile-v2.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

3 images are downloaded at several times the size a phone draws them, for example features-magnus-pro-home-splash-poster-mobile-v2.jpg at 1,700 px wide, shown at 390 px. Resized copies would save about 234 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 12.99 g of CO₂e: 1558.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 element use ARIA attributes their role does not allow, which confuses screen readers.

1 dropdown has no label.

2 elements hidden from screen readers can still receive keyboard focus.

Interactive controls must not be nested: 2 elements on the page fail this check, rated serious by axe-core.

Heading levels should only increase by one: 1 element on the page fails this check, rated moderate by axe-core.

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

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

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

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

Elements with role="dialog" or role="alertdialog" do not have accessible names. (1 element).

Elements with visible text labels do not have matching accessible names. (3 elements).

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

Structured data found (Organization) but with 1 problem, for example “Organization: url points at a different host (https://secretlab.co)”.

10 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to only 2 pages on your own site, so visitors and crawlers find few routes into the rest of it.

2 links have no real href, so search engines can't follow them.

A phone browser shows 1,347 words, but the HTML your server sends has only 6. GPTBot, ClaudeBot and PerplexityBot read that HTML without running JavaScript, so they see an almost empty page. Server-side rendering or pre-rendering fixes it.

https://secretlab.eu/collections/promotions has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 1 page linked from your homepage and read each the way a search engine does.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

3 errors were logged to the browser console while the page loaded, for example “Invalid navigation declaration: Invalid element ID [node HTMLDivElement]”.

Large scripts ship without source maps.

1 image is served at too low a resolution for sharp phone screens.

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.

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 1,347 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Klaviyo (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 12 cookies (measured from a US location before any click).

Loading the homepage contacts 37 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
