spluss.com website review

The page has 8,477 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 4.0 s on main-thread work while loading, 2.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Intercom and Clarity and others), adding 1.5 MB and 885 ms of main-thread time.

Your mobile performance score is 60. Pages that score under 90 lose visitors before the first paint.

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

About 788 KiB of JavaScript is downloaded but never used on this page.

Google Tag Manager costs a phone 328 ms of main-thread work and 521 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.

Shopify costs a phone 84 ms of main-thread work and 458 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.

About 55 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.

11 long tasks block the main thread while loading, the longest for 188 ms. During a long task the page ignores taps.

22 files are served with short cache lifetimes, so returning visitors download them again (90 KiB).

7 images could be 111 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

8 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 50 ms faster on a phone.

8 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.

The page becomes fully interactive after 21.5 s. Good is under 3.8 s.

Your largest element takes 5.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Choose your ideal temperature—with RYMASKON®! Smart room au…”.

Visually, the page fills in at 6.4 s (Speed Index). Good is under 3.4 s.

Real visitors wait 2.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

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

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 453 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.5 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 140 ms to 148 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 2.6 s to 2.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 7.8 MB in 347 requests on a phone: media 3.4 MB (2), other files 1.8 MB (185) and scripts 1.6 MB (90). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 2.20 g of CO₂e: 263.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must contain particular children: 3 elements on the page fail this check, rated critical by axe-core.

1 button has no accessible name, so screen readers announce just “button”.

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

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

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

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

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (2 elements).

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

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

The homepage links to 408 pages on spluss.com and 7 external pages.

/collections/all, /policies/shipping-policy, /collections/sale, /collections/digitale-raumthermostate-rymaskon, /collections/wireless and /pages/jobs-career and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /collections/digitale-raumthermostate-rymaskon, whose canonical is /collections/digital-room-thermostats-rymaskon. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/collections/all, /policies/shipping-policy, /collections/sale, /collections/digitale-raumthermostate-rymaskon, /collections/wireless and /pages/jobs-career and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

/collections/all, /collections/sale, /collections/digitale-raumthermostate-rymaskon and /collections/wireless have 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 197 found) and read each the way a search engine does.

The page uses 1 deprecated browser API that will stop working in future browsers (“Synchronous `XMLHttpRequest` on the main thread is deprecated because of its detrimental effects to…”).

4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

2 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

spluss.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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

Social proof on the homepage: 21 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage carries about 1,491 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

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

Opening the homepage sets 18 cookies, 2 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 39 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
