tu-chemnitz.de website review

25 images could be 523 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 750 ms faster on a phone.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 700 ms.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 550 ms).

About 36 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.

25 files are served with short cache lifetimes, so returning visitors download them again (62 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.

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 209 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors wait 1.2 s for your server to start answering (75th percentile). Good is under 800 ms.

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

Your largest element takes 2.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “3 persons looking into the camera”. Most of its time is resource load duration (1.2 s).

Visually, the page fills in at 3.6 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 130 ms to 130 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 1.0 s to 1.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

11 images (575 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.

16 images further down the page (555 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 EFRE-ESF_en.png at 1,235 px wide, shown at 390 px. Resized copies would save about 5 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.29 g of CO₂e: 34.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Your meta description is only 31 characters: “Technische Universität Chemnitz”. 70 to 160 characters is enough to sell the click.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

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

No XML sitemap at https://www.tu-chemnitz.de/sitemap.xml, so Google discovers your pages only by following links.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 116 pages on tu-chemnitz.de and 26 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 https://www.tu-chemnitz.de/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.

https://www.tu-chemnitz.de/tu/wtc/index.html.en is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://www.tu-chemnitz.de/tu/wtc/index.html.en has no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://www.tu-chemnitz.de/career-service/jobboerse/index.php, whose canonical is https://www.tu-chemnitz.de/career-service/jobboerse. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://www.tu-chemnitz.de/studium/index.php.en took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 100 found) and read each the way a search engine does.

3 of 15 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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 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.

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.

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.
