vilros.com website review

A phone's processor spends 4.8 s on main-thread work while loading, 1.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,429 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 1.4 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

8 third-party services load with your homepage (Shopify, voiceflow.com and Google CDN and others), adding 2.3 MB and 986 ms of main-thread time.

26 files are served with short cache lifetimes, so returning visitors download them again (1.1 MB).

Your mobile performance score is 62. Pages that score under 90 lose visitors before the first paint.

8 images could be 146 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

Shopify costs a phone 288 ms of main-thread work and 808 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.

voiceflow.com costs a phone 162 ms of main-thread work and 582 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.

Google CDN costs a phone 137 ms of main-thread work and 333 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.

cloudfront.net costs a phone 112 ms of main-thread work and 387 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.

5 long tasks block the main thread while loading, the longest for 246 ms. During a long task the page ignores taps.

12 files block the first paint until they finish downloading. Deferring or inlining them could save about 100 ms.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 44 KiB JavaScript that modern phones do not need.

About 27 KiB of CSS is downloaded but never applied on this page.

14 KiB could be saved by minifying JavaScript.

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.

3 KiB JavaScript is shipped twice across bundles.

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.

The page becomes fully interactive after 21.5 s. Good is under 3.8 s.

Visually, the page fills in at 9.7 s (Speed Index). Good is under 3.4 s.

Your largest element takes 5.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Real visitors wait 280 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 209 ms to 256 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 1.9 s (75th percentile). Good is under 1.8 s.

The first text or image appears after 2.2 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 295 ms in total while the page loads. Good is under 200 ms.

Your homepage downloads 4.8 MB in 350 requests on a phone: scripts 2.7 MB (150), other files 880 KiB (117) and images 786 KiB (22). Under 2 MB keeps phones on slow connections fast.

raspberry-pi-tall.jpg 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).

1 image (76 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 1.36 g of CO₂e: 163.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 frame has no title, so screen-reader users cannot tell what it contains.

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

All page content should be contained by landmarks: 9 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.

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

Elements with visible text labels do not have matching accessible names. (3 elements).

Your title is 75 characters, so Google will cut it off around 60: “Raspberry Pi Store | Raspberry Pi 5 | Raspberry Pi 4 | Arduino – Vilros.com”.

Your meta description is 260 characters; Google truncates after about 160, so the end of your pitch is cut.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

Your <h1> is empty.

The homepage links to 170 pages on vilros.com and 7 external pages.

https://vilros.com/collections/raspberry-pi-boards, https://vilros.com/collections/raspberry-pi-all-power-supplies, https://vilros.com/collections/raspberry-pi-all-cases, https://vilros.com/collections/pimoroni, https://vilros.com/collections/adafruit and https://vilros.com/collections/argon-fourty and 3 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://vilros.com/collections/cables-wires took over 3 s to send its HTML from our server.

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

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

3 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://d1npnstlfekkfz.cloudfront.net/zipify-oneclickupsell-single.bfbdb0cfc9f155eb.css' f…”.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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 534 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 4 mores (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 28 cookies, 1 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 48 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
