ktc.co.th website review

Google Tag Manager costs a phone 3.5 s of main-thread work and 1.9 MB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

106 files are served with short cache lifetimes, so returning visitors download them again (1.0 MB).

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

Your mobile performance score is 37. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 9.5 s on main-thread work while loading, 6.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Facebook and Hotjar and others), adding 2.3 MB and 4.1 s of main-thread time.

About 1,015 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

20 long tasks block the main thread while loading, the longest for 743 ms. During a long task the page ignores taps.

Facebook costs a phone 322 ms of main-thread work and 233 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.

The page has 1,652 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

4 images could be 207 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 24 KiB JavaScript that modern phones do not need.

About 12 KiB of CSS is downloaded but never applied on this page.

8 KiB could be saved by minifying CSS.

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.

Scripts block taps and scrolling for 3.9 s in total while the page loads. Good is under 200 ms.

The page becomes fully interactive after 21.7 s. Good is under 3.8 s.

Visually, the page fills in at 11.9 s (Speed Index). Good is under 3.4 s.

Your largest element takes 6.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “สำหรับพัฒนาประสิทธิภาพการทำงานเว็บไซต์ เพื่อมอบประสบการณ์กา…”.

Real visitors wait 256 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 202 ms to 330 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The first text or image appears after 1.9 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.3 s to 2.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.5 MB in 145 requests on a phone: scripts 2.8 MB (97), images 439 KiB (22) and fonts 99 KiB (4). Under 2 MB keeps phones on slow connections fast.

1 image (80 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 0.99 g of CO₂e: 118.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

All page content should be contained by landmarks: 64 elements on the page fail this check, rated moderate by axe-core.

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

Alternative text of images should not be repeated as text: 12 elements on the page fail this check, rated minor by axe-core.

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

There is no robots.txt at ktc.co.th/robots.txt, the first file search crawlers ask for.

The homepage links to 113 pages on ktc.co.th and 0 external pages.

https://www.ktc.co.th/about and https://www.ktc.co.th/careers all use the title “KTC : บริษัท บัตรกรุงไทย จำกัด (มหาชน)”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.ktc.co.th/about, https://www.ktc.co.th/careers and https://www.ktc.co.th/ushop use the same meta description. A description written for each page earns more clicks.

https://www.ktc.co.th/about, https://www.ktc.co.th/investor-relations, https://www.ktc.co.th/sustainability-development, https://www.ktc.co.th/careers, https://www.ktc.co.th/loan/ktc-cash and https://www.ktc.co.th/ktc-p-berm and 1 other have 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.

https://www.ktc.co.th/about/announcement, https://www.ktc.co.th/loan/ktc-cash, https://www.ktc.co.th/ktc-p-berm, https://www.ktc.co.th/rewards, https://www.ktc.co.th/installment and https://www.ktc.co.th/ktcmobile took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 70 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://www.ktc.co.th/upload/KTC-Home-page-Mobile-banner-9OCT-1100x1692.webp.

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

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 57 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 Analytics, Google Tag Manager, Hotjar and Meta 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 13 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 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
