dywidag.com website review

About 1.2 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 8.6 s faster on a phone.

5 images could be 481 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 2.5 s faster on a phone.

Your mobile performance score is 33. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.7 s on main-thread work while loading, 2.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (YouTube, Google CDN and Google Tag Manager and others), adding 2.9 MB and 1.5 s of main-thread time.

10 files are served with short cache lifetimes, so returning visitors download them again (81 KiB).

About 212 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 590 ms faster on a phone.

YouTube costs a phone 548 ms of main-thread work and 1,014 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.

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

Google CDN costs a phone 407 ms of main-thread work and 734 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 369 ms of main-thread work and 373 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.

13 long tasks block the main thread while loading, the longest for 335 ms. During a long task the page ignores taps.

Contentful costs a phone 0 ms of main-thread work and 561 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.

Polyfills for old browsers add 13 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

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 first text or image appears after 13.2 s on a phone. Good is under 1.8 s.

Your largest element takes 25.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “This site uses third-party website tracking technologies to…”.

The page becomes fully interactive after 25.9 s. Good is under 3.8 s.

Visually, the page fills in at 13.2 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 1.1 s in total while the page loads. Good is under 200 ms.

Real visitors wait 2.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.0 s (75th percentile). 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 122 ms to 134 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 2.1 s to 2.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.3 MB in 120 requests on a phone: scripts 2.4 MB (50), other files 1.0 MB (31) and images 533 KiB (20). Under 2 MB keeps phones on slow connections fast.

1 image further down the page (27 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.22 g of CO₂e: 146.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has 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 74 characters, so Google will cut it off around 60: “DYWIDAG | Innovative Infrastructure Solutions for Global Markets | DYWIDAG”.

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

Your meta description is 162 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 78 pages on dywidag.com and 0 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.

/projects, /downloads, /press and /products have no meta description, so Google writes the search snippet from whatever text it finds.

/contact has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 70 found) and read each the way a search engine does.

5 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

Chrome logged issues while loading the page (“Cookie”).

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.

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

dywidag.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.

dywidag.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.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 471 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 and Google Tag Manager (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 1 cookie, 1 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 25 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
