desmi.com website review

23 files are served with short cache lifetimes, so returning visitors download them again (322 KiB).

The page has 3,300 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 741 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 960 ms faster on a phone.

Your mobile performance score is 73. Pages that score under 90 lose visitors before the first paint.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 950 ms.

7 third-party services load with your homepage (Google CDN, Cookiebot and Google Tag Manager and others), adding 1.6 MB and 612 ms of main-thread time.

Google CDN costs a phone 339 ms of main-thread work and 1.1 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 47 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 60 ms faster on a phone.

10 long tasks block the main thread while loading, the longest for 89 ms. During a long task the page ignores taps.

1 image could be 67 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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

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 14.0 s. Good is under 3.8 s.

Your largest element takes 5.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Child joyfully runs through water from an open fire hydrant…”.

Real visitors wait 3.2 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.1 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.4 s for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 4.5 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 129 ms to 152 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 2.9 s to 3.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.7 MB in 49 requests on a phone: scripts 1.5 MB (13), other files 350 KiB (2) and fonts 347 KiB (15). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.76 g of CO₂e: 91.2 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”.

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

Your title is 75 characters, so Google will cut it off around 60: “Pumps and systems for your critical flow processes | DESMI - Make life flow”.

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

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

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

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 346 pages on desmi.com and 13 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 /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.

We fetched 15 pages linked from your homepage (of 150 found) and read each the way a search engine does.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

HSTS is set, but max-age is 30 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.

desmi.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

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 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 951 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 Tag Manager (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

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

Loading the homepage contacts 8 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
