deprag.com website review

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

Your mobile performance score is 84 (desktop: 89). Pages that score under 90 lose visitors before the first paint.

6 images could be 756 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 200 ms faster on a phone.

About 79 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

About 54 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 300 ms).

2 long tasks block the main thread while loading, the longest for 254 ms. During a long task the page ignores taps.

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

3 files are served with short cache lifetimes, so returning visitors download them again (16 KiB).

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.

1 third-party service load with your homepage (VWO), adding 6 KiB and 0 ms of main-thread time.

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 4.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Real visitors wait 208 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors wait 1.3 s for your server to start answering (75th percentile). Good is under 800 ms.

The page becomes fully interactive after 4.6 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 210 ms to 207 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

deprag-italia-team-teaser.png weighs 557 KiB. On a phone connection a single image that size takes seconds.

csm_product-teaser-zufuehrtechnik_9c1991c4f1.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).

3 images (699 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

3 images further down the page (699 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

1 image is downloaded at several times the size a phone draws it, for example deprag-italia-team-teaser.png at 1,478 px wide, shown at 308 px. Resized copies would save about 339 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.36 g of CO₂e: 43.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 frame has no title, so screen-reader users cannot tell what it contains.

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

All page content should be contained by landmarks: 19 elements on the page fail this check, rated moderate by axe-core.

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

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.

6 visible links have no text or label, so screen readers cannot say where they go.

4 form fields have no label, so screen readers announce an empty box and autofill guesses.

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

The homepage links to 203 pages on deprag.com and 10 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.

/de and /de/index.html all use the title “DEPRAG › Weltweit führend in Technik & Innovation”, and 1 other title repeat too. Search engines can't tell which page to show for a search, so each competes with the others.

/en/index.html and /en use the same meta description. A description written for each page earns more clicks.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /en, whose canonical is /en/index.html. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 125 found) and read each the way a search engine does.

18 of 31 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

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

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

Opening https://deprag.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.

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

deprag.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.

deprag.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.

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.

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

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

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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

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 533 words of visible text.

deprag.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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.

Opening the homepage sets 11 cookies (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 1 host run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
