aiwin.com.tw website review

11 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.0 s.

About 271 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.4 s faster on a phone.

A phone's processor spends 4.3 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 63. Pages that score under 90 lose visitors before the first paint.

4 images could be 77 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 350 ms faster on a phone.

The page has 2,081 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

10 long tasks block the main thread while loading, the longest for 190 ms. During a long task the page ignores taps.

2 third-party services load with your homepage (Google Tag Manager and Google Analytics), adding 179 KiB and 139 ms of main-thread time.

About 76 KiB of JavaScript is downloaded but never used on this page.

19 files are served with short cache lifetimes, so returning visitors download them again (39 KiB).

Polyfills for old browsers add 12 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.

Your largest element takes 5.0 s to render on a phone. Google's threshold for “good” is 2.5 s.

Visually, the page fills in at 7.2 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 8.6 s. Good is under 3.8 s.

Real visitors see the first content after 2.0 s (75th percentile). Good is under 1.8 s.

The first text or image appears after 2.7 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 337 ms in total while the page loads. Good is under 200 ms.

Your homepage downloads 4.4 MB in 91 requests on a phone: media 2.3 MB (3), images 766 KiB (21) and scripts 620 KiB (41). Under 2 MB keeps phones on slow connections fast.

1 image is downloaded at several times the size a phone draws it, for example industry-semiconductor-tech.jpg at 1,024 px wide, shown at 169 px. Resized copies would save about 54 KiB.

1 image (72 KiB) is 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 1.25 g of CO₂e: 149.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Elements must only use permitted ARIA attributes: 1 element on the page fails this check, rated serious by axe-core.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

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

Elements with visible text labels do not have matching accessible names. (1 element).

The homepage links to 67 pages on aiwin.com.tw and 10 external pages.

We fetched 15 pages linked from your homepage (of 31 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

Social proof on the homepage: 24 customer or partner logos. Pairing it with named testimonials or customer logos makes it far more convincing.

The homepage shows no opening hours. If customers visit or call, show when.

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

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 539 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (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 3 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 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
