Speed

1 to fix98

  • Use efficient cache lifetimes

    50 ms · 530 KiB

    25 files are served with short cache lifetimes, so returning visitors download them again (530 KiB).

  • Reduce unused CSS

    30 KiB

    About 30 KiB of CSS is downloaded but never applied on this page.

  • Legacy JavaScript

    10 KiB

    Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need.

  • 1 third-party service on the page

    1 third-party service load with your homepage (Cloudflare), adding 10 KiB and 6 ms of main-thread time.

  • Chained critical requests

    Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

3 checks passed

  • Mobile performance score: 98

    98/100

    Your mobile performance score is 98. That is in Google's “good” band (90 and up).

  • Main-thread work: 0.2 s

    A phone's processor spends 0.2 s on main-thread work while loading, 29 ms of it running JavaScript. That is comfortably low.

  • Server response: 28 ms

    28 ms

    Your server sent the HTML in 28 ms, well inside Google's 600 ms guideline.

Core Web Vitals

4 to fix67

  • Fails Core Web Vitals for real visitors

    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-user INP: 206 ms

    206 ms

    Real visitors wait 206 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

  • 16 images without width and height

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

  • First Contentful Paint: 1.8 s

    1.8 s

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

11 checks passed

  • Real-user LCP: 1.0 s

    1.0 s

    Real visitors wait 1.0 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Real-user CLS: 0.01

    0.01

  • Real-user FCP: 1.0 s

    1.0 s

    Real visitors see the first content after 1.0 s (75th percentile). Good is under 1.8 s.

  • Real-user TTFB: 498 ms

    498 ms

    Real visitors wait 498 ms for your server to start answering (75th percentile). Good is under 800 ms.

  • Tap response (INP) got 45% faster for real visitors

    -45%

    Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 312 ms to 179 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest content (LCP) got 10% faster for real visitors

    -10%

    Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.2 s to 1.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest Contentful Paint: 1.9 s

    1.9 s

    Your largest element renders in 1.9 s on a phone, inside Google's 2.5 s “good” threshold. The largest element is the text “Du bringst den Einsatz. Wir bringen die Jobs, die zu deinem…”.

  • Cumulative Layout Shift: 0.002

    0.002

    The layout barely moves while loading (CLS 0.002, good is under 0.1).

  • Speed Index: 1.9 s

    1.9 s

    Visually, the page fills in at 1.9 s (Speed Index), inside the 3.4 s “good” threshold.

  • Total Blocking Time: 0 ms

    0 ms

    Scripts block the page for only 0 ms while loading. Good is under 200 ms.

  • Time to Interactive: 1.9 s

    1.9 s

    The page is fully interactive after 1.9 s.

Images and page weight

100

  • 1 image below the first screen load straight away

    1 image further down the page (20 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

  • About 0.2 g of CO₂ per visit

    0.16 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.16 g of CO₂e: 19.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 checks passed

  • Page weight: 586 KiB in 27 requests

    586 KiB

    Your homepage downloads 586 KiB in 27 requests on a phone: fonts 390 KiB (6), images 99 KiB (16) and HTML 49 KiB (1). That is a lean page.

  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • Images are sized for phones

    No image is downloaded at more than three times the size it is drawn on a phone.

Accessibility

1 to fixGoogle 9397

  • 1 tap target too small

    1 tap target is too small or too close together to hit reliably with a finger.

  • Headings skip levels

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

2 checks passed

  • Every image has alt text

    All 60 images in the HTML carry an alt attribute.

  • 37 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 39 WCAG 2.2 A/AA and best-practice rules on the phone render: 37 passed and 2 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

4 to fixGoogle 9282

  • Title is long (76 characters)

    Your title is 76 characters, so Google will cut it off around 60: “Zenjob | Flexible Nebenjobs für Studierende | Moderner Personaldienstleister”.

  • 2 H1 headlines

    There are 2 <h1> headlines (“Personal, personalisiert.” and “Dein Einsatz. Dein Job.”). One clear main headline is easier for people and search engines.

  • No XML sitemap

    No XML sitemap at https://www.zenjob.com/sitemap_index.xml, so Google discovers your pages only by following links.

  • 4 links crawlers can't follow

    4 links have no real href, so search engines can't follow them.

  • 318 internal links, 34 external

    The homepage links to 318 pages on zenjob.com and 34 external pages.

5 checks passed

  • Meta description: 135 characters

    Your meta description is 135 characters: “Zenjob ist die Job-App für Nebenjobs & Studentenjobs. Wir bringen Unternehmen, die Personal suchen & motivierte Mitarbe…”.

  • Canonical URL set

    The canonical URL is https://www.zenjob.com/de/.

  • Structured data in place

    Structured data found: BreadcrumbList, ImageObject, Organization, WebPage and WebSite.

  • Open Graph tags complete

    Open Graph tags are complete, so shared links show a title, description and image.

  • robots.txt in place

    robots.txt is in place and points crawlers to your sitemap.

AI search readiness

100

  • No llms.txt

    There is no https://www.zenjob.com/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.

3 checks passed

  • AI answer engines may read the site

    Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.

  • Organization data: 4 of 6 facts

    Your Organization JSON-LD gives name, url, logo and sameAs (social profiles); description and contact details would complete it.

  • Text is in the HTML

    Your server sends the page's text in the HTML (1,589 words), so crawlers that don't run JavaScript still read it.

Other pages

100

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 75 found) and read each the way a search engine does.

7 checks passed

  • Linked pages load

    All 15 pages we checked loaded without an error.

  • Canonical URLs point to themselves

    No page we checked hands its ranking to a different URL.

  • Every page has a meta description

    All 15 pages that loaded have a meta description.

  • Titles are unique

    Every page we checked has its own title.

  • Every page has an H1

    Each page we checked has a main headline.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 15 pages that loaded have a <title>.

Best practices

Google 100100
3 checks passed

  • No console errors

    No JavaScript errors were logged while the page loaded on a phone.

  • Tap targets are thumb-sized

    9 of 10 tappable elements near the top are at least 24 px.

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

3 to fix67

  • No call to action on the first screen

    On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

  • Thin social proof

    Social proof on the homepage: 6 customer or partner logos. Pairing it with named testimonials or customer logos makes it far more convincing.

  • No direct contact details

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

  • No risk reducer

    No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

  • About 1,140 words of copy

    The homepage carries about 1,140 words of visible text.

3 checks passed

  • 5 calls to action

    The homepage has 5 calls to action, for example “Call Center”.

  • 3 short forms

    3 short forms (1 field at most) are right on the homepage.

  • Analytics in place

    Analytics detected: Google Tag Manager and Cloudflare Web Analytics.

Privacy and tracking

  • No consent tool detected

    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.

  • 1 other company contacted

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

1 checks passed

  • No known trackers before consent

    No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).

Security, domain, email and software versions

The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at zenjob.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
