delkin.com website review

About 1.1 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 7.0 s faster on a phone.

56 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.5 s.

About 204 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.

A phone's processor spends 4.1 s on main-thread work while loading, 1.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

7 third-party services load with your homepage (Google Tag Manager, Google CDN and Other Google APIs/SDKs and others), adding 1.7 MB and 914 ms of main-thread time.

Your mobile performance score is 50 (desktop: 62). Pages that score under 90 lose visitors before the first paint.

Google Tag Manager costs a phone 468 ms of main-thread work and 938 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 CDN costs a phone 407 ms of main-thread work and 733 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 22 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

The page has 1,624 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

3 files are served with short cache lifetimes, so returning visitors download them again (4 KiB).

4 images could be 153 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

14 long tasks block the main thread while loading, the longest for 144 ms. During a long task the page ignores taps.

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.

Real visitors wait 6.3 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 5.7 s (75th percentile). Good is under 1.8 s.

Real visitors wait 2.3 s for your server to start answering (75th percentile). Good is under 800 ms.

The first text or image appears after 10.9 s on a phone. Good is under 1.8 s.

Your largest element takes 23.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 24.3 s. Good is under 3.8 s.

Visually, the page fills in at 11.3 s (Speed Index). Good is under 3.4 s.

Real visitors wait 329 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 135 ms to 328 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Scripts block taps and scrolling for 284 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 5.5 s to 6.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.6 MB in 194 requests on a phone: scripts 2.4 MB (83), images 2.2 MB (24) and stylesheets 377 KiB (71). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.60 g of CO₂e: 192.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

8 tap targets are too small or too close together to hit reliably with a finger.

1 element hidden from screen readers can still receive keyboard focus.

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

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

The skip-link target should exist and be focusable: 1 element on the page fails this check, rated moderate by axe-core.

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

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

Headings skip levels (h2 → h5 and h2 → h4), which makes the page harder to scan with a screen reader.

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

4 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 209 pages on delkin.com and 9 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.

/deutsche, /about-delkin, /about-delkin/delkin-difference, /about-delkin/partners, /about-delkin/built-to-order-in-the-united-states and /technology and 8 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 79 found) and read each the way a search engine does.

17 of 33 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Unexpected token ':'”.

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.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

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.

delkin.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.

delkin.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.

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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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.

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 507 words of visible text.

DMARC is set to p=none, so mail pretending to be delkin.com is still delivered. Reports are on, so moving to quarantine is the next step.

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). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 10 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 9 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
