crossknowledge.com website review

48 files are served with short cache lifetimes, so returning visitors download them again (2.0 MB).

8 third-party services load with your homepage (Google Tag Manager, Hubspot and Osano CMP and others), adding 632 KiB and 951 ms of main-thread time.

Your mobile performance score is 70. Pages that score under 90 lose visitors before the first paint.

Google Tag Manager costs a phone 544 ms of main-thread work and 369 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 2.9 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

11 long tasks block the main thread while loading, the longest for 280 ms. During a long task the page ignores taps.

The page has 1,575 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 199 KiB of JavaScript is downloaded but never used on this page.

2 images could be 119 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 29 KiB of CSS is downloaded but never applied on this page.

Polyfills for old browsers add 24 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 14.2 s. Good is under 3.8 s.

Visually, the page fills in at 8.4 s (Speed Index). Good is under 3.4 s.

For real visitors the layout shifts by 0.20 (75th percentile). Good is under 0.1.

Real visitors wait 911 ms for your server to start answering (75th percentile). Good is under 800 ms.

The first text or image appears after 2.9 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 443 ms in total while the page loads. Good is under 200 ms.

Your largest element takes 2.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Where learning drives future workforce capability”. Most of its time is element render delay (2.4 s).

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

Your homepage downloads 2.8 MB in 85 requests on a phone: images 1.7 MB (38), scripts 766 KiB (19) and fonts 194 KiB (9). Under 2 MB keeps phones on slow connections fast.

18 images further down the page (1.1 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

7 images are downloaded at several times the size a phone draws them, for example integration-and-apis-1200x900-1.png at 1,200 px wide, shown at 258 px. Resized copies would save about 233 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.81 g of CO₂e: 96.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must be contained by particular parents: 4 elements on the page fail this check, rated critical by axe-core.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

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

1 element hidden from screen readers can still receive keyboard focus.

Some lists contain elements other than list items, which screen readers announce wrongly.

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

1 visible link has no text or label, so screen readers cannot say where it goes.

Headings skip levels (h3 → h5 and h3 → h6), which makes the page harder to scan with a screen reader.

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

The homepage links to 174 pages on crossknowledge.com and 23 external pages.

There is no /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.

/learning-platform/crossknowledge-avatar is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

We fetched 15 pages linked from your homepage (of 67 found) and read each the way a search engine does.

56 of 73 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Unexpected end of input”.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

crossknowledge.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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 1,415 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, HubSpot and Microsoft Clarity (measured from a US location before any click). A consent tool (Osano) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 12 cookies (measured from a US location before any click).

Loading the homepage contacts 22 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
