vinchin.com website review

142 files are served with short cache lifetimes, so returning visitors download them again (3.3 MB).

About 445 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.4 s faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 1.6 s).

16 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

26 images could be 1.3 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Your mobile performance score is 65 (desktop: 36). Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, reddit and LiveChat and others), adding 1.2 MB and 545 ms of main-thread time.

About 76 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.

Google Tag Manager costs a phone 361 ms of main-thread work and 530 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.

LiveChat costs a phone 38 ms of main-thread work and 587 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.

14 KiB could be saved by minifying CSS.

8 KiB could be saved by minifying JavaScript.

6 long tasks block the main thread while loading, the longest for 132 ms. During a long task the page ignores taps.

Polyfills for old browsers add 11 KiB JavaScript that modern phones do not need.

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.

Real visitors wait 4.1 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 3.5 s (75th percentile). Good is under 1.8 s.

Real visitors wait 2.4 s for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 15.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Vinchin Backup & Recovery Next-Generation Data Protection P…”.

The page becomes fully interactive after 19.6 s. Good is under 3.8 s.

Visually, the page fills in at 7.3 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' tap response (inp) went from 176 ms to 195 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.3 MB in 182 requests on a phone: images 3.1 MB (92), scripts 1.4 MB (49) and fonts 712 KiB (5). Under 2 MB keeps phones on slow connections fast.

2 images are downloaded at several times the size a phone draws them, for example nst-distributor-cover.png at 3,126 px wide, shown at 360 px. Resized copies would save about 539 KiB.

17 images (1.6 MB) are 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.

6 images further down the page (750 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.50 g of CO₂e: 180.3 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.

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

1 link inside paragraphs relies on colour alone to stand out.

All page content should be contained by landmarks: 27 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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

Your title is 68 characters, so Google will cut it off around 60: “Vinchin Backup & Recovery | VM Backup, VM Migration and DR | Vinchin”.

Your meta description is 247 characters; Google truncates after about 160, so the end of your pitch is cut.

Structured data found (Organization, Service, SoftwareApplication and VideoObject) but with 4 problems, for example “WebSite: missing name”.

No XML sitemap at https://www.vinchin.com/sitemap.xml, so Google discovers your pages only by following links.

6 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

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

Your hreflang tags are invalid, so Google may show the wrong language version.

The homepage links to 148 pages on vinchin.com and 13 external pages.

We fetched 15 pages linked from your homepage (of 112 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=56376817&tm=gtm002&Ver=2&mid=586db77a-98f6-42a6-a6fd-053cf8052e15&bo=1&sid=a15d82c0cafd11f1a0459787aec4beb5&vid=a15d8820cafd11f192321f47eab43c59&vids=1&msclkid=N&pi=91.

4 of 15 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

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.

The homepage shows no opening hours. If customers visit or call, show when.

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 1,322 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Microsoft Ads and Reddit 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 16 cookies, 4 of them by other companies (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 18 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
