ksmartech.com website review

41 files are served with short cache lifetimes, so returning visitors download them again (6.3 MB).

About 540 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.9 s faster on a phone.

9 images could be 1.2 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Your mobile performance score is 61. Pages that score under 90 lose visitors before the first paint.

6 third-party services load with your homepage (kakaocdn.net, Google Tag Manager and Kakao and others), adding 4.4 MB and 331 ms of main-thread time.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 600 ms.

About 85 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

JSDelivr CDN costs a phone 0 ms of main-thread work and 3.7 MB 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.

YouTube costs a phone 0 ms of main-thread work and 464 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.

3 long tasks block the main thread while loading, the longest for 69 ms. During a long task the page ignores taps.

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

Your largest element takes 29.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “K smartech”.

The page becomes fully interactive after 30.2 s. Good is under 3.8 s.

Visually, the page fills in at 10.0 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.1 s on a phone. Good is under 1.8 s.

8 images 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.

Your homepage downloads 10.0 MB in 45 requests on a phone: images 4.7 MB (26), fonts 3.7 MB (5) and scripts 1.4 MB (10). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 2.83 g of CO₂e: 340.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

All page content should be contained by landmarks: 5 elements on the page fail this check, rated moderate by axe-core.

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

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

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

Your title is only 25 characters: “케이스마텍 | 암호키 보안 전문기업 KEY4C”. Between 30 and 65 characters leaves room to say what you do and for whom.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

Structured data found (Organization) but with 1 problem, for example “Organization: sameAs is an empty list”.

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

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

There is no https://www.ksmartech.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.

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 81 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 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 2 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 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
