viacloud.nl website review

32 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.3 s.

Your mobile performance score is 75. Pages that score under 90 lose visitors before the first paint.

6 third-party services load with your homepage (Google Tag Manager, Google CDN and Other Google APIs/SDKs and others), adding 1.4 MB and 678 ms of main-thread time.

About 622 KiB of JavaScript is downloaded but never used on this page.

Google Tag Manager costs a phone 363 ms of main-thread work and 553 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 266 ms of main-thread work and 743 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.

A phone's processor spends 2.4 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 1,709 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 250 ms).

11 long tasks block the main thread while loading, the longest for 136 ms. During a long task the page ignores taps.

About 33 KiB of CSS is downloaded but never applied on this page.

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

4 KiB could be saved by minifying JavaScript.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 117 ms to 115 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 3.6 s to 3.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.5 MB in 110 requests on a phone: scripts 1.4 MB (38), other files 362 KiB (11) and images 261 KiB (15). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.71 g of CO₂e: 84.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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: 31 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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

4 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.

Headings skip levels (h2 → h4, h1 → h4 and h1 → h4), which makes the page harder to scan with a screen reader.

Elements with visible text labels do not have matching accessible names. (1 element).

There are 5 <h1> headlines (“#1 in Network, Security, Forensic and Wireshark T…”, “01” and “02”). One clear main headline is easier for people and search engines.

Structured data found (Article, ImageObject, Person and WebPage) but with 1 problem, for example “WebSite: missing name”.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

9 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 77 pages on viacloud.nl and 3 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.

https://tcpiptraining.com/news has no meta description, so Google writes the search snippet from whatever text it finds.

https://tcpiptraining.com/trainingen-courses, https://tcpiptraining.com/news, https://tcpiptraining.com/contact, https://tcpiptraining.com/trainingen-courses/tcp-ip-analysis-with-wireshark, https://tcpiptraining.com/trainingen-courses/network-forensics-analysis and https://tcpiptraining.com/trainingen-courses/workshop-cyber-security-network-forensics-analysis and 6 others have no <h1> headline, so visitors and search engines get no clear main topic.

https://tcpiptraining.com/news took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 30 found) and read each the way a search engine does.

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: 2 trust badges. 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 586 words of visible text.

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 4 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 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
