vcc.co website review

33 images could be 10.9 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 14.1 s faster on a phone.

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.4 s.

About 608 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.4 s faster on a phone.

About 393 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.9 s faster on a phone.

6 files are served with short cache lifetimes, so returning visitors download them again (289 KiB).

Your mobile performance score is 55 (desktop: 66). Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, web.app and watermelon.ai and others), adding 1,020 KiB and 569 ms of main-thread time.

Polyfills for old browsers add 73 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 400 ms faster on a phone.

62 KiB could be saved by minifying JavaScript.

Google Tag Manager costs a phone 251 ms of main-thread work and 323 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.

A phone's processor spends 2.2 s on main-thread work while loading, 810 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 1,805 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

web.app costs a phone 98 ms of main-thread work and 315 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.

4 long tasks block the main thread while loading, the longest for 208 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 200 ms).

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 4.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 3.4 s (75th percentile). Good is under 1.8 s.

Your largest element takes 33.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 36.5 s. Good is under 3.8 s.

The first text or image appears after 5.1 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 8.2 s (Speed Index). Good is under 3.4 s.

Real visitors wait 1.7 s for your server to start answering (75th percentile). Good is under 800 ms.

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' largest content (lcp) went from 4.6 s to 4.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 16.1 MB in 130 requests on a phone: images 12.7 MB (54), fonts 1.4 MB (13) and scripts 1.3 MB (33). Under 2 MB keeps phones on slow connections fast.

8 images weigh 7.0 MB together. On a phone connection a single image that size takes seconds.

12 images are downloaded at several times the size a phone draws them, for example ChatGPT-Image-17-sept-2026-01_58_30-p.m.png at 1,536 px wide, shown at 340 px. Resized copies would save about 4.5 MB.

17 images (9.1 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.

SOUND-1.png is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 4.55 g of CO₂e: 546.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

40 elements hidden from screen readers can still receive keyboard focus.

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

18 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 3 elements on the page fail this check, rated moderate by axe-core.

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

Headings skip levels (h1 → h5 and h1 → h4), which makes the page harder to scan with a screen reader.

There are 11 <h1> headlines (“Powered by unmatched expertise and capabilities, …”, “Murata EOL Replacement” and “Industries We Serve”). One clear main headline is easier for people and search engines.

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

The homepage links to 104 pages on vcc.co and 5 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

https://vcc.co/product-category/sound-devices and https://vcc.co/product-category/switches use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 44 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://chatwidget-css.web.app/assets/widget-button.module.css?v=18d526b18b5cf311' from or…”.

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

1 image is served at too low a resolution for sharp phone screens.

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 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 457 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, 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 9 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 20 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
