tdcnet.dk website review

39 files are served with short cache lifetimes, so returning visitors download them again (493 KiB).

6 images could be 1.1 MB 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.

Your mobile performance score is 73. Pages that score under 90 lose visitors before the first paint.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 700 ms.

About 114 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 460 ms faster on a phone.

3 third-party services load with your homepage (jQuery CDN, Bootstrap CDN and JSDelivr CDN), adding 56 KiB and 88 ms of main-thread time.

9 KiB could be saved by minifying JavaScript.

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

Your largest element takes 5.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Ny forside - DK”.

Visually, the page fills in at 5.1 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.4 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 5.5 s. Good is under 3.8 s.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 148 ms to 156 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.3 s to 1.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.1 MB in 52 requests on a phone: images 1.6 MB (12), fonts 243 KiB (2) and scripts 174 KiB (35). Under 2 MB keeps phones on slow connections fast.

6 images (570 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.60 g of CO₂e: 72.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 buttons have no accessible name, so screen readers announce just “button”.

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.

3 frames have no title, so screen-reader users cannot tell what they contain.

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

2 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.

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

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

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

There are 6 <h1> headlines (“Seneste nyt”, “Forbindelsen er TDC NET” and “Kan 5G hjælpe naturen?”). One clear main headline is easier for people and search engines.

Open Graph is missing og:description, so shared links fall back to guesses.

The homepage links to 76 pages on tdcnet.dk and 7 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://tdcnet.dk/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://tdcnet.dk/presse/danmarks-bedste-mobilnet-for-11-aar-i-traek-stationaert-og-paa-farten and https://tdcnet.dk/presse/foerste-televirksomhed-i-virksomhedsberedskabet-tdc-net-er-med-til-at-styrke-danmarks-beredskab are marked noindex but linked from your homepage. If they are meant to be found, remove the noindex.

https://tdcnet.dk/investor-relations has no meta description, so Google writes the search snippet from whatever text it finds.

https://tdcnet.dk/infrastruktur and https://tdcnet.dk/om-os/hvem-er-tdc-net use the same meta description. A description written for each page earns more clicks.

https://tdcnet.dk/partner/international and https://tdcnet.dk/fiber/udbydere have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 35 found) and read each the way a search engine does.

23 of 75 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.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

Social proof on the homepage: 5 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

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 1,644 words of visible text.

Before a visitor clicks anything, the page loads 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 2 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 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
