koenig-solutions.com website review

Your mobile performance score is 45 (desktop: 91). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

The page has 7,562 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 6.4 s on main-thread work while loading, 2.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 1.2 MB of JavaScript is downloaded but never used on this page.

6 third-party services load with your homepage (Google CDN, Other Google APIs/SDKs and jQuery CDN and others), adding 1.2 MB and 846 ms of main-thread time.

Google CDN costs a phone 705 ms of main-thread work and 1.1 MB 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.

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

About 52 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.

17 long tasks block the main thread while loading, the longest for 266 ms. During a long task the page ignores taps.

7 images could be 71 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.

10 KiB could be saved by minifying CSS.

32 KiB could be saved by minifying JavaScript.

1 file is served with short cache lifetimes, so returning visitors download them again (11 KiB).

Desktop scores 91 but mobile only 45. A gap that wide usually means heavy scripts and images that hit phones hardest.

Polyfills for old browsers add 8 KiB JavaScript that modern phones do not need.

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.

The page becomes fully interactive after 11.6 s. Good is under 3.8 s.

The layout shifts by 0.354 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Visually, the page fills in at 6.7 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 740 ms in total while the page loads. Good is under 200 ms.

Real visitors wait 2.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 364 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors see the first content after 2.1 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.6 s for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 4.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Cybersecurity Skills”. Most of its time is element render delay (2.1 s).

2 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 412 ms to 471 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 3.0 s to 3.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.4 MB in 89 requests on a phone: scripts 1.2 MB (16), other files 391 KiB (12) and fonts 301 KiB (5). Under 2 MB keeps phones on slow connections fast.

1 image (63 KiB) is 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 0.67 g of CO₂e: 80.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Interactive controls must not be nested: 4 elements on the page fail this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 26 elements on the page fail this check, rated moderate by axe-core.

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

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

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

Structured data found (Organization, WebPage and WebSite) but with 2 problems, for example “Organization: sameAs is not an absolute URL ("https://www.facebook.com/ KoenigSolutions/")”.

The homepage links to 1,160 pages on koenig-solutions.com and 22 external pages.

There is no https://www.koenig-solutions.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.

https://www.koenig-solutions.com/ec-council-training-certification-courses declares the homepage as its canonical URL, which tells Google it is a copy of the homepage and keeps it out of search results. A site-wide template setting usually causes this.

/ and https://www.koenig-solutions.com/ec-council-training-certification-courses all use the title “Online IT Course and Certification Company - Koenig Solutions”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.koenig-solutions.com/microsoft-training-certification-courses, https://www.koenig-solutions.com/cisco-training-certification-courses, https://www.koenig-solutions.com/koenig-originals-course, https://www.koenig-solutions.com/aws-training, https://www.koenig-solutions.com/pecb-training-certification-courses and https://www.koenig-solutions.com/vmware-training-certification-courses and 7 others have no <h1> headline, so visitors and search engines get no clear main topic.

https://www.koenig-solutions.com/koenig-originals-course and https://www.koenig-solutions.com/oracle-training-certification-courses took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 199 found) and read each the way a search engine does.

23 of 53 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Synchronous `XMLHttpRequest` on the main thread is deprecated because of its detrimental effects to…”).

1 error was logged to the browser console while the page loaded, for example “Cannot read properties of undefined (reading 'register')”.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

The homepage carries about 3,169 words of visible text.

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.
