ngbiotech.com website review

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

6 images could be 1.0 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 3.2 s faster on a phone.

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

Your mobile performance score is 65 (desktop: 80). Pages that score under 90 lose visitors before the first paint.

About 121 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.

Cookiebot costs a phone 345 ms of main-thread work and 155 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 2.1 s on main-thread work while loading, 854 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

2 third-party services load with your homepage (Cookiebot and Google Tag Manager), adding 333 KiB and 345 ms of main-thread time.

8 long tasks block the main thread while loading, the longest for 149 ms. During a long task the page ignores taps.

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

About 27 KiB of JavaScript is downloaded but never used on this page.

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.

4 KiB could be saved by minifying JavaScript.

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

The page becomes fully interactive after 15.2 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.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 2.7 s to 3.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.8 s (75th percentile). Good is under 1.8 s.

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

Visually, the page fills in at 5.5 s (Speed Index). Good is under 3.4 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 205 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 90 ms to 88 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Banner-homepage-3.png weighs 1.3 MB. On a phone connection a single image that size takes seconds.

Your homepage downloads 3.7 MB in 51 requests on a phone: images 2.9 MB (13), scripts 593 KiB (23) and stylesheets 126 KiB (6). Under 2 MB keeps phones on slow connections fast.

10 images (2.8 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.

3.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 1.05 g of CO₂e: 126.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA dialog and alertdialog nodes should have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

Main landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one main landmark: 1 element on the page fails this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

Headings skip levels (h3 → h5), which makes the page harder to scan with a screen reader.

No meta description, so Google writes its own snippet from whatever text it finds.

There is no <h1>, so neither visitors nor Google get a clear main headline.

No Open Graph image (also missing: og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

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

The homepage links to 65 pages on ngbiotech.com and 18 external pages.

https://www.ngbiotech.com/about-us, https://www.ngbiotech.com/products, https://www.ngbiotech.com/antimicrobial-resistance, https://www.ngbiotech.com/ng-test-carba-5, https://www.ngbiotech.com/ng-test-ctx-m-multi and https://www.ngbiotech.com/ng-test-mcr-1 and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 25 found) 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: the server responded with a status of 404 ()”.

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.

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 277 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Loading the homepage contacts 3 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
