naturecan.tw website review

A phone's processor spends 23.5 s on main-thread work while loading, 6.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Shopify costs a phone 1.8 s of main-thread work and 1.1 MB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

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

typeform.com costs a phone 1.1 s of main-thread work and 699 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Your mobile performance score is 32. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

The page has 8,237 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Shopify, typeform.com and Klaviyo and others), adding 2.6 MB and 4.1 s of main-thread time.

20 long tasks block the main thread while loading, the longest for 695 ms. During a long task the page ignores taps.

34 images could be 582 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Klaviyo costs a phone 515 ms of main-thread work and 309 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.

26 files are served with short cache lifetimes, so returning visitors download them again (364 KiB).

Reviews.io costs a phone 445 ms of main-thread work and 356 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 476 KiB of JavaScript is downloaded but never used on this page.

About 59 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

13 KiB could be saved by minifying JavaScript.

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.

The page becomes fully interactive after 31.5 s. Good is under 3.8 s.

Scripts block taps and scrolling for 3.2 s in total while the page loads. Good is under 200 ms.

Your largest element takes 6.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Main tw 99購物節-Mobile.png__PID:9a4fa44b-a90d-4c16-82ea-37eab…”.

Visually, the page fills in at 10.4 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.3 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.5 s to 1.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 7.7 MB in 645 requests on a phone: images 4.1 MB (225), scripts 2.0 MB (239) and other files 869 KiB (142). Under 2 MB keeps phones on slow connections fast.

Main_TW-11.11_SALE-Mobile.png 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).

9 images (303 KiB) 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.

By the Sustainable Web Design model, a visit to your homepage emits about 2.17 g of CO₂e: 260.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Scrollable region must have keyboard access: 41 elements on the page fail this check, rated serious by axe-core.

Elements must only use permitted ARIA attributes: 34 elements on the page fail this check, rated serious by axe-core.

All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

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

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

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

Your meta description is only 61 characters: “Naturecan是來自英國的專業營養保健品牌，提供元性的商品, 從營養保健、美容保養到健身補給，多款高品質商品供您選擇。”. 70 to 160 characters is enough to sell the click.

There are 2 <h1> headlines (“Naturecan TW” and “我適合什麼產品？”). One clear main headline is easier for people and search engines.

The homepage links to 165 pages on naturecan.tw and 2 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), 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.

Your homepage links to https://www.naturecan.tw/products/anti-ageing-longevity-bundle, https://www.naturecan.tw/products/glp-1-bundle and https://www.naturecan.tw/products/gut-health-bundle, which answer with an error. Visitors hit a dead end and search engines drop them.

https://www.naturecan.tw/collections/all has no meta description, so Google writes the search snippet from whatever text it finds.

https://www.naturecan.tw/collections/all, https://www.naturecan.tw/collections/naturecan-products, https://www.naturecan.tw/collections, https://www.naturecan.tw/products/silica-supplement-bloosil, https://www.naturecan.tw/products/longevity-powder-mix and https://www.naturecan.tw/products/glp-1-supplement and 6 others have no <h1> headline, so visitors and search engines get no clear main topic.

https://www.naturecan.tw/products/zinc-supplement, https://www.naturecan.tw/products/urolithin-a, https://www.naturecan.tw/products/apigenin-supplement and https://www.naturecan.tw/products/magnesium-gummies took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 75 found) and read each the way a search engine does.

6 of 27 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

3 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

3 errors were logged to the browser console while the page loaded, for example “Cannot read properties of null (reading 'getElementsByTagName')”.

Chrome logged issues while loading the page (“Cookie”).

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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 370 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Klaviyo (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 14 cookies, 2 of them by other companies (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 30 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
