arkcrystals.com website review

About 655 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.9 s faster on a phone.

13 files are served with short cache lifetimes, so returning visitors download them again (184 KiB).

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.

Your mobile performance score is 59. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Intercom, Shopify and pop-convert.com and others), adding 1.1 MB and 460 ms of main-thread time.

The page has 2,465 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 2.4 s on main-thread work while loading, 804 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Shopify costs a phone 93 ms of main-thread work and 495 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.

About 20 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

3 long tasks block the main thread while loading, the longest for 82 ms. During a long task the page ignores taps.

Polyfills for old browsers add 9 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.

3 KiB could be saved by minifying JavaScript.

Your largest element takes 23.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Where Physics Touches Lives Every drop, every breath, every…”.

The page becomes fully interactive after 23.8 s. Good is under 3.8 s.

The first text or image appears after 5.4 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 7.3 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 112 ms to 104 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 4.5 MB in 229 requests on a phone: other files 2.9 MB (120), scripts 1.3 MB (71) and fonts 103 KiB (4). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.28 g of CO₂e: 154.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Headings skip levels (h2 → h5 and h2 → h4), which makes the page harder to scan with a screen reader.

Your title is 68 characters, so Google will cut it off around 60: “ARK Crystals | Biotechnology for ultimate wellbeing – ARK Technology”.

There are 2 <h1> headlines (“” and “Where Physics Touches Lives”). One clear main headline is easier for people and search engines.

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

The homepage links to 13 pages on arkcrystals.com and 4 external pages.

Your Organization JSON-LD is missing logo, description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

/pages/about and /collections/ark-technology have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 7 pages linked from your homepage and read each the way a search engine does.

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

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.

Social proof on the homepage: 16 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

There is no form on the homepage, so every lead has to click through to another page first.

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 828 words of visible text.

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

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, Meta Pixel and Microsoft Clarity and 2 mores (measured from a US location before any click). A consent tool (CookieYes) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 21 cookies (measured from a US location before any click).

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