prenetics.com website review

21 images could be 6.1 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 8.7 s faster on a phone.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.0 s.

About 306 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.6 s faster on a phone.

8 third-party services load with your homepage (website-files.com, Google Optimize and cloudfront.net and others), adding 8.8 MB and 251 ms of main-thread time.

Your mobile performance score is 57 (desktop: 78). Pages that score under 90 lose visitors before the first paint.

website-files.com costs a phone 83 ms of main-thread work and 8.5 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.

About 58 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

2 files are served with short cache lifetimes, so returning visitors download them again (15 KiB).

3 long tasks block the main thread while loading, the longest for 115 ms. During a long task the page ignores taps.

12 KiB could be saved by minifying CSS.

6 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.

Your largest element takes 19.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “NASDAQ: PRE Prenetics. The company behind IM8”.

The page becomes fully interactive after 19.3 s. Good is under 3.8 s.

Visually, the page fills in at 8.9 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.8 s on a phone. Good is under 1.8 s.

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

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 11.4 MB in 63 requests on a phone: images 8.3 MB (38), media 2.3 MB (1) and scripts 668 KiB (12). Under 2 MB keeps phones on slow connections fast.

69422445c4bb73dc80e67511_IM8_DB_HERO_1248-min (1)-p-500.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).

4 images (152 KiB) 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.

By the Sustainable Web Design model, a visit to your homepage emits about 3.24 g of CO₂e: 388.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

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

ARIA input fields must have an accessible name: 2 elements on the page fail this check, rated serious by axe-core.

All page content should be contained by landmarks: 11 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.

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

The robots meta tag says “noindex”: Google is told not to list this page at all.

Google's crawler is blocked from indexing this page.

Your title is 67 characters, so Google will cut it off around 60: “Prenetics | The World's Fastest Growing Consumer Healthcare Company”.

Structured data found (Corporation) but with 1 problem, for example “Corporation: url is not an absolute URL ("/")”.

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.

The homepage links to 8 pages on prenetics.com and 21 external pages.

There is no /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.

Your homepage links to /btc, which answers with an error. Visitors hit a dead end and search engines drop it.

/about-us, /contact-us and /resources use the same meta description. A description written for each page earns more clicks.

/about-us and /contact-us have no <h1> headline, so visitors and search engines get no clear main topic.

/contact-us and /resources 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.

We fetched 4 pages linked from your homepage and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

Large scripts ship without source maps.

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.

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.

The homepage carries about 859 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 3 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 12 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
