isomat.eu website review

Your mobile performance score is 86 (desktop: 92). Pages that score under 90 lose visitors before the first paint.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 600 ms.

Google Tag Manager costs a phone 291 ms of main-thread work and 516 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 324 KiB of JavaScript is downloaded but never used on this page.

The page has 1,598 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

4 third-party services load with your homepage (Google Tag Manager, isomat.gr and Google/Doubleclick Ads and others), adding 670 KiB and 498 ms of main-thread time.

7 long tasks block the main thread while loading, the longest for 131 ms. During a long task the page ignores taps.

About 21 KiB of CSS is downloaded but never applied on this page.

2 images could be 17 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.

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.

Real visitors wait 2.1 s for your server to start answering (75th percentile). Good is under 800 ms.

The page becomes fully interactive after 12.5 s. Good is under 3.8 s.

Visually, the page fills in at 8.5 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 2.7 s (75th percentile). Good is under 1.8 s.

Scripts block taps and scrolling for 263 ms in total while the page loads. Good is under 200 ms.

7 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 3.6 s to 3.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

By the Sustainable Web Design model, a visit to your homepage emits about 0.56 g of CO₂e: 67.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

9 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.

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

Your title is 187 characters, so Google will cut it off around 60: “ISOMAT S.A. - Waterproofing Materials, Concrete And Mortar Additives, Polyurethane System…”.

Your meta description is 216 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.

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

The homepage links to 208 pages on isomat.eu and 64 external pages.

https://www.isomat.eu/useful-tools, https://www.isomat.eu/company/esg/sustainability/isomat-sustainable-future, https://www.isomat.eu/company/esg/sustainability/contribution-of-products-to-sustainable-structures, https://www.isomat.eu/company/esg/sustainability/certified-products and https://www.isomat.eu/company/esg/sustainability/integrated-system-solutions-green-building have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.isomat.eu/contact has no <h1> headline, so visitors and search engines get no clear main topic.

https://www.isomat.eu/company/esg/sustainability/integrated-system-solutions-green-building took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 66 found) and read each the way a search engine does.

12 of 41 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

Social proof on the homepage: 4 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

The homepage carries about 411 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.

Loading the homepage contacts 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
