vnpay.vn website review

66 files are served with short cache lifetimes, so returning visitors download them again (6.8 MB).

About 1.3 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 5.3 s faster on a phone.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 4.7 s.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 1.9 s).

About 278 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.2 s faster on a phone.

12 images could be 2.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

8 third-party services load with your homepage (edgevnpay.vn, Google Tag Manager and TikTok and others), adding 8.0 MB and 1.1 s of main-thread time.

edgevnpay.vn costs a phone 475 ms of main-thread work and 7.1 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.

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

Google Tag Manager costs a phone 325 ms of main-thread work and 513 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.

48 KiB could be saved by minifying CSS.

A phone's processor spends 2.4 s on main-thread work while loading, 1.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

11 long tasks block the main thread while loading, the longest for 139 ms. During a long task the page ignores taps.

Polyfills for old browsers add 72 KiB JavaScript that modern phones do not need.

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

Visually, the page fills in at 16.9 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 36.6 s. Good is under 3.8 s.

Real visitors wait 3.0 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.1 s (75th percentile). Good is under 1.8 s.

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 207 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 211 ms to 225 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 8.0 MB in 98 requests on a phone: images 3.3 MB (22), scripts 2.6 MB (47) and stylesheets 824 KiB (4). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 2.27 g of CO₂e: 271.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

2 tap targets are too small or too close together to hit reliably with a finger.

Your meta description is 168 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 25 pages on vnpay.vn and 15 external pages.

There is no https://vnpay.vn/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://vnpay.vn/ve-chung-toi and https://vnpay.vn/lien-he use the same meta description. A description written for each page earns more clicks.

https://vnpay.vn/lien-he 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.

https://vnpay.vn/tin-tuc, https://vnpay.vn/lien-he and https://vnpay.vn/uu-dai-1-trieu-khi-mo-tai-khoan-vietabank-093n0809lk96 took over 3 s to send their HTML from our server.

We fetched 8 pages linked from your homepage and read each the way a search engine does.

5 of 19 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 “Connecting to 'https://analytics-ipv6.tiktokw.us/ipv6/enrich_ipv6' violates the following Content Security Policy direc…”.

13 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

Chrome logged issues while loading the page (“Content security policy”).

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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

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.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 977 words of visible text.

Before a visitor clicks anything, the page loads 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 5 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 3 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
