kobrekim.com website review

About 342 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.8 s faster on a phone.

16 files are served with short cache lifetimes, so returning visitors download them again (326 KiB).

8 third-party services load with your homepage (Google Tag Manager, Facebook and Hotjar and others), adding 946 KiB and 1.1 s of main-thread time.

Your mobile performance score is 54. Pages that score under 90 lose visitors before the first paint.

Google Tag Manager costs a phone 430 ms of main-thread work and 490 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.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 300 ms.

Facebook costs a phone 265 ms of main-thread work and 224 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.

12 long tasks block the main thread while loading, the longest for 268 ms. During a long task the page ignores taps.

A phone's processor spends 2.4 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

1 image could be 40 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

Polyfills for old browsers add 26 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 50 ms faster on a phone.

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 9.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Hong Kong Office”.

The page becomes fully interactive after 11.2 s. Good is under 3.8 s.

Scripts block taps and scrolling for 809 ms in total while the page loads. Good is under 200 ms.

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 4.0 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 77 ms to 73 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.6 s to 1.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

1 image (55 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 0.33 g of CO₂e: 39.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 buttons have no accessible name, so screen readers announce just “button”.

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

3 form fields have no label, so screen readers announce an empty box and autofill guesses.

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

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

The homepage links to 161 pages on kobrekim.com and 2 external pages.

There is no https://kobrekim.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

https://kobrekim.com/zh-hans has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage (of 54 found) and read each the way a search engine does.

4 of 16 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

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

Social proof on the homepage: 3 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

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

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

The homepage carries about 526 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and HubSpot and 3 mores (measured from a US location before any click). A consent tool (HubSpot cookie banner) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 19 cookies (measured from a US location before any click).

Loading the homepage contacts 33 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
