deli.cards website review

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.7 s.

Your mobile performance score is 76. Pages that score under 90 lose visitors before the first paint.

14 files are served with short cache lifetimes, so returning visitors download them again (197 KiB).

About 73 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.

17 images could be 354 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

8 third-party services load with your homepage (Reviews.io, Clarity and Shopify and others), adding 457 KiB and 177 ms of main-thread time.

About 36 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

1 long task block the main thread while loading, the longest for 65 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

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

Real visitors wait 3.0 s for the largest content to appear (75th percentile). Good is under 2.5 s.

The page becomes fully interactive after 6.9 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 179 ms to 179 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 3.3 s to 3.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.4 MB in 159 requests on a phone: images 1.1 MB (35), other files 615 KiB (59) and scripts 492 KiB (47). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.69 g of CO₂e: 82.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA attributes must conform to valid values: 1 element on the page fails this check, rated critical by axe-core.

5 elements hidden from screen readers can still receive keyboard focus.

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

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

All page content should be contained by landmarks: 2 elements on the page fail 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.

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

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 25 characters: “Deli Cards von SCHEE GmbH”. Between 30 and 65 characters leaves room to say what you do and for whom.

No Open Graph image (also missing: og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 81 pages on deli.cards and 4 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

/customer_authentication/redirect has no <title>, so Google invents the link text in results.

/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/customer_authentication/redirect has no meta description, so Google writes the search snippet from whatever text it finds.

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

We fetched 15 pages linked from your homepage (of 45 found) and read each the way a search engine does.

18 of 62 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

1 link go through two or more redirects, for example https://deli.cards/customer_authentication/redirect?locale=en&region_country=DE.

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.

deli.cards 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.

deli.cards'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.

Social proof on the homepage: 1 testimonial or review block. Pairing it with named testimonials or customer logos makes it far more convincing.

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

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 385 words of visible text.

DMARC is set to p=none, so mail pretending to be deli.cards is still delivered. Add a report address, check the reports, then move to quarantine.

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.

Before a visitor clicks anything, the page loads Klaviyo and Microsoft Clarity (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 8 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 17 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
