40 images could be 4.6 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 3.3 s faster on a phone.

About 1.1 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 5.8 s faster on a phone.

Your mobile performance score is 40. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.5 s on main-thread work while loading, 2.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page goes through 1 redirect before it starts loading, costing about 901 ms. Link and advertise the final URL directly.

Polyfills for old browsers add 40 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 350 ms faster on a phone.

ZenDesk costs a phone 97 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.

10 files are served with short cache lifetimes, so returning visitors download them again (200 KiB).

8 third-party services load with your homepage (ZenDesk, Klaviyo and Facebook and others), adding 610 KiB and 269 ms of main-thread time.

19 long tasks block the main thread while loading, the longest for 211 ms. During a long task the page ignores taps.

About 54 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.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

The HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.

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.

5 KiB could be saved by minifying JavaScript.

4 KiB could be saved by minifying CSS.

The first text or image appears after 8.4 s on a phone. Good is under 1.8 s.

Your largest element takes 53.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “為 iPhone 18 Pro 而生”.

The page becomes fully interactive after 54.1 s. Good is under 3.8 s.

Visually, the page fills in at 13.9 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 602 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 2.0 s to 2.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

9 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 145 ms to 145 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 13.1 MB in 365 requests on a phone: images 6.0 MB (72), scripts 3.1 MB (173) and other files 2.4 MB (80). Under 2 MB keeps phones on slow connections fast.

2 images are downloaded at several times the size a phone draws them, for example tw_homepage_banner_double11_sm.jpg at 2,250 px wide, shown at 390 px. Resized copies would save about 340 KiB.

1 image further down the page (123 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 3.70 g of CO₂e: 444.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is only 26 characters: “犀牛盾｜官方網站 – 犀牛盾 RHINOSHIELD”. Between 30 and 65 characters leaves room to say what you do and for whom.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

Your meta description is 175 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

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

Large scripts ship without source maps.

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 testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 63 words of visible text; thin pages give Google and first-time buyers little to go on.

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.

Before a visitor clicks anything, the page loads Google Ads, Google Tag Manager, Klaviyo, Meta Pixel and TikTok Pixel (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 15 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 28 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
