16lab.net website review

About 761 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.6 s faster on a phone.

35 files are served with short cache lifetimes, so returning visitors download them again (394 KiB).

14 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.6 s.

Your mobile performance score is 43. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (YouTube, Google Tag Manager and Google Analytics and others), adding 1.4 MB and 590 ms of main-thread time.

YouTube costs a phone 402 ms of main-thread work and 1,013 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.

About 132 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 400 ms).

5 long tasks block the main thread while loading, the longest for 130 ms. During a long task the page ignores taps.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

5 KiB could be saved by minifying JavaScript.

1 image could be 4 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Your largest element takes 13.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “OZONTM”.

The layout shifts by 1 while loading, so content jumps under the reader's thumb. Good is under 0.1.

The page becomes fully interactive after 13.9 s. Good is under 3.8 s.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 3.9 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 227 ms in total while the page loads. Good is under 200 ms.

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.

1 image (31 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 0.56 g of CO₂e: 67.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

All page content should be contained by landmarks: 6 elements on the page fail this check, rated moderate by axe-core.

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

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

Your title is only 5 characters: “16Lab”. Between 30 and 65 characters leaves room to say what you do and for whom.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

Open Graph is missing og:description, so shared links fall back to guesses.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 17 pages on 16lab.net and 0 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.

There is no https://16lab.net/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://16lab.net/2024/02/06/16lab-selected-to-the-jetro-beyond-japan-program-in-austin-tx_en/1742, https://16lab.net/about, https://16lab.net/news, https://16lab.net/join-the-family, https://16lab.net/press-kits and https://16lab.net/company-values and 1 other have no meta description, so Google writes the search snippet from whatever text it finds.

https://16lab.net/join-the-family, https://16lab.net/press-kits, https://16lab.net/company-values and https://16lab.net/contact-us 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 7 pages linked from your homepage and read each the way a search engine does.

5 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

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 (Not Found)”.

Chrome logged issues while loading the page (“Cookie”).

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.

The homepage has only about 133 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

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 5 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 11 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
