ccjk.com website review

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 650 ms.

About 21 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.

About 279 KiB of JavaScript is downloaded but never used on this page.

Google Tag Manager costs a phone 210 ms of main-thread work and 315 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.

The page has 1,924 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

tidio.co costs a phone 68 ms of main-thread work and 515 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.

5 third-party services load with your homepage (Google Tag Manager, tidio.co and Clarity and others), adding 882 KiB and 348 ms of main-thread time.

4 files are served with short cache lifetimes, so returning visitors download them again (54 KiB).

3 long tasks block the main thread while loading, the longest for 159 ms. During a long task the page ignores taps.

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

1 image could be 4 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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 see the first content after 3.1 s (75th percentile). Good is under 1.8 s.

The page becomes fully interactive after 8.2 s. Good is under 3.8 s.

Real visitors wait 3.2 s for the largest content to appear (75th percentile). Good is under 2.5 s.

For real visitors the layout shifts by 0.16 (75th percentile). Good is under 0.1.

Real visitors wait 1.7 s for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 4.0 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 145 ms to 149 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 3.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.8 MB in 85 requests on a phone: images 2.8 MB (52), scripts 830 KiB (16) and fonts 135 KiB (3). Under 2 MB keeps phones on slow connections fast.

3 images further down the page (857 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 home_banner_bg.webp at 3,840 px wide, shown at 390 px. Resized copies would save about 63 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.09 g of CO₂e: 130.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Form elements should have a visible label: 4 elements on the page fail this check, rated serious by axe-core.

ARIA input fields must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

Links must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

2 images have no alt text, which hurts accessibility and image search.

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

ARIA role should be appropriate for the element: 4 elements on the page fail this check, rated minor by axe-core.

Elements marked as presentational should be consistently ignored: 4 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h1 → h5, h2 → h6 and h2 → h6), which makes the page harder to scan with a screen reader.

Structured data found (BreadcrumbList, Organization, Product and WebPage) but with 1 problem, for example “Product: no offers (price) block”.

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

6 links have no real href, so search engines can't follow them.

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

The homepage links to 130 pages on ccjk.com and 10 external pages.

Your robots.txt lets ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User), Claude (Claude-User) and Perplexity (PerplexityBot) read the homepage but closes other sections to them, so answers about those pages can't cite you.

We fetched 15 pages linked from your homepage (of 69 found) and read each the way a search engine does.

5 of 7 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 “Failed to load resource: net::ERR_FAILED”.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

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.

ccjk.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

ccjk.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.

Your longest form asks for 8 fields (0 required). Every extra field lowers completion.

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 1,618 words of visible text.

DMARC is set to p=none, so mail pretending to be ccjk.com is still delivered. Reports are on, so moving to quarantine is the next step.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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 and Microsoft Clarity (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 21 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.
