gancube.com website review

Not measured in this review.

• Fails Core Web Vitals for real visitors

  Real Chrome users on phones do not pass Google's Core Web Vitals on your site (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

• Real-user INP: 259 ms

  259 ms

  Real visitors wait 259 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

• Tap response (INP) got 36% slower for real visitors

  +36%

  Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 179 ms to 250 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

• Largest content (LCP) held steady for real visitors

  +8%

  Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.8 s to 2.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

• Page weight: 9.4 MB

  9.4 MB

  Your homepage downloads 9.4 MB on a phone, 6.5 MB of it images (69%). Under 2 MB keeps phones on slow connections fast.

• 2 images over 500 KB

  2 images weigh 1.1 MB together. On a phone connection a single image that size takes seconds.

  Elements (2)

• 3 images in older formats

  3 images (1.4 MB) 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.

  Elements (3)

• An image on the first screen is lazy-loaded

  GAN17_banner_1.webp is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

  Elements (1)

• 2 images far larger than shown

  40 KiB

  2 images are downloaded at several times the size a phone draws them, for example GAN17_jurassic_mb.webp at 1,200 px wide, shown at 390 px. Resized copies would save about 40 KiB.

  Elements (2)

• About 2.7 g of CO₂ per visit

  2.68 g

  By the Sustainable Web Design model, a visit to your homepage emits about 2.68 g of CO₂e: 321.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

• Links must have discernible text (3 elements)

  Links must have discernible text: 3 elements on the page fail this check, rated serious by axe-core.

  Elements (3)

• 3 tap targets too small

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

  Elements (3)

• Frames without titles

  1 frame has no title, so screen-reader users cannot tell what it contains.

  Elements (1)

• Interactive controls must not be nested (1 element)

  Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

  Elements (1)

• All page content should be contained by landmarks (1 element)

  All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

  Elements (1)

• 3 form fields without a label

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

  View source

• Headings skip levels

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

  View source

• Title is long (70 characters)

  Your title is 70 characters, so Google will cut it off around 60: “Speed Cubes, Smart Cubes for World Champion | GANCUBE Official Website”.

  View source

• Meta description is long (209 characters)

  Your meta description is 209 characters; Google truncates after about 160, so the end of your pitch is cut.

  View source

• Structured data has 1 problem

  Structured data found (Organization and WebSite) but with 1 problem, for example “Organization: sameAs is an empty list”.

  View source

• 420 internal links, 22 external

  The homepage links to 420 pages on gancube.com and 22 external pages.

• No llms.txt

  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.

• 1 page without an H1

  /collections/all has no <h1> headline, so visitors and search engines get no clear main topic.

• 15 internal pages checked

  We fetched 15 pages linked from your homepage (of 115 found) and read each the way a search engine does.

• 6 JavaScript errors while loading

  6 errors were logged to the browser console while the page loaded, for example “Plyr is not defined”.

• 1 broken external link

  1 link to other sites is dead, for example https://apps.apple.com/app/id1524781423 (404).

• Short HSTS lifetime

  HSTS is set, but max-age is 91 days; one year is the recommended minimum.

• No Referrer-Policy

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

• No Permissions-Policy

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

• Deprecated X-XSS-Protection

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

• No security.txt

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

• DNSSEC is off

  gancube.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 risk reducer

  No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

• About 1,082 words of copy

  The homepage carries about 1,082 words of visible text.

• Email authentication score: 90/100

  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.

• 5 trackers load before any consent

  5

  Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel 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.

• 19 cookies set on arrival

  19

  Opening the homepage sets 19 cookies, 1 of them by other companies (measured from a US location before any click).

• No consent tool detected

  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.

• 43 other companies contacted

  Loading the homepage contacts 43 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
