hydragun.hk website review

About 314 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.7 s faster on a phone.

11 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.6 s.

13 files are served with short cache lifetimes, so returning visitors download them again (197 KiB).

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

A phone's processor spends 3.1 s on main-thread work while loading, 1.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Shopify costs a phone 73 ms of main-thread work and 595 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.

8 third-party services load with your homepage (Facebook, Clarity and Klaviyo and others), adding 892 KiB and 405 ms of main-thread time.

5 long tasks block the main thread while loading, the longest for 142 ms. During a long task the page ignores taps.

3 images could be 128 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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

Polyfills for old browsers add 31 KiB JavaScript that modern phones do not need.

About 13 KiB of CSS is downloaded but never applied on this page.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

4 KiB could be saved by minifying CSS.

Your largest element takes 10.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Man using Hydragun Atom Mini Massage Gun”.

The first text or image appears after 3.8 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 10.1 s. Good is under 3.8 s.

Visually, the page fills in at 6.6 s (Speed Index). Good is under 3.4 s.

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

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.

640x920_mobile_banner_male_atom_v2-min.jpg 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).

1 image is downloaded at several times the size a phone draws it, for example 640x920_mobile_banner_male_atom_v2-min.jpg at 1,281 px wide, shown at 390 px. Resized copies would save about 19 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.53 g of CO₂e: 63.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

21 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 2 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.

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

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

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

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

Your meta description is only 25 characters: “高端康復科技和產品能讓大家緩解疼痛，加速恢復健康。”. 70 to 160 characters is enough to sell the click.

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

5 links have no real href, so search engines can't follow them.

The homepage links to 33 pages on hydragun.hk and 28 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.

https://www.hydragun.hk/pages/contact, https://www.hydragun.hk/policies/terms-of-service and https://www.hydragun.hk/pages/shipping-and-returns have no meta description, so Google writes the search snippet from whatever text it finds.
