nvnmarine.com website review

About 193 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 44. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

7 third-party services load with your homepage (Google CDN, Clarity and Other Google APIs/SDKs and others), adding 562 KiB and 520 ms of main-thread time.

Google CDN costs a phone 210 ms of main-thread work and 296 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 2.3 s on main-thread work while loading, 1.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

6 long tasks block the main thread while loading, the longest for 200 ms. During a long task the page ignores taps.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

6 files are served with short cache lifetimes, so returning visitors download them again (50 KiB).

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.

Your largest element takes 9.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

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

The page becomes fully interactive after 9.2 s. Good is under 3.8 s.

The layout shifts by 0.315 while loading, so content jumps under the reader's thumb. Good is under 0.1.

For real visitors the layout shifts by 0.23 (75th percentile). Good is under 0.1.

Visually, the page fills in at 4.6 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 272 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 117 ms to 112 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.5 MB in 225 requests on a phone: other files 964 KiB (149), scripts 634 KiB (43) and images 542 KiB (14). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.71 g of CO₂e: 85.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

<dt> and <dd> elements must be contained by a <dl>: 8 elements on the page fail this check, rated serious by axe-core.

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

1 form field has no label, so screen readers announce an empty box and autofill guesses.

1 visible link has no text or label, so screen readers cannot say where it goes.

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

Elements with visible text labels do not have matching accessible names. (9 elements).

The homepage links to 90 pages on nvnmarine.com and 5 external pages.

There is no https://nvnmarine.com/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.

https://nvnmarine.com/pages/about-us and https://nvnmarine.com/pages/contact-us have no meta description, so Google writes the search snippet from whatever text it finds.

https://nvnmarine.com/collections has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 53 found) and read each the way a search engine does.

The homepage carries about 829 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Microsoft Ads and 1 more (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 13 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 26 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
