ciat.com website review

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.5 s.

About 210 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.

About 171 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.2 s faster on a phone.

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

5 files are served with short cache lifetimes, so returning visitors download them again (65 KiB).

5 third-party services load with your homepage (Google Tag Manager, Optanon and carriercms.com and others), adding 612 KiB and 242 ms of main-thread time.

Polyfills for old browsers add 9 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

5 long tasks block the main thread while loading, the longest for 92 ms. During a long task the page ignores taps.

3 images could be 31 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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 7.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “ciat-comfort-line-x-banner-en-h”.

The page becomes fully interactive after 7.7 s. Good is under 3.8 s.

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

For real visitors the layout shifts by 0.21 (75th percentile). Good is under 0.1.

Real visitors see the first content after 2.6 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.8 s for your server to start answering (75th percentile). Good is under 800 ms.

The layout shifts by 0.217 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Visually, the page fills in at 4.2 s (Speed Index). Good is under 3.4 s.

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

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.3 s to 2.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

abound-hvac-performance-ciat-h.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).

By the Sustainable Web Design model, a visit to your homepage emits about 0.28 g of CO₂e: 33.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 2 elements on the page fail this check, rated moderate by axe-core.

Document should not have more than one contentinfo landmark: 1 element on the page fails this check, rated moderate by axe-core.

Elements with visible text labels do not have matching accessible names. (1 element).

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

Your title is 69 characters, so Google will cut it off around 60: “European expert in air conditioning and heating systems | CIAT Europe”.

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

The homepage links to 89 pages on ciat.com and 8 external pages.

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 61 found) and read each the way a search engine does.

Opening https://ciat.com goes through 2 redirects before the homepage loads.

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.

ciat.com is registered until Dec 2026. Make sure auto-renew is on and the card on file is current.

ciat.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.

ciat.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.

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.

The homepage carries about 321 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 and Google Tag Manager (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 8 cookies (measured from a US location before any click).

Loading the homepage contacts 6 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
