atslab.com website review

16 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.3 s.

About 1.4 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

Your mobile performance score is 80. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Cookiebot, Cloudflare CDN and d41.co and others), adding 820 KiB and 576 ms of main-thread time.

6 files are served with short cache lifetimes, so returning visitors download them again (100 KiB).

Cookiebot costs a phone 442 ms of main-thread work and 157 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.

6 images could be 454 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

The page has 2,831 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 2.3 s on main-thread work while loading, 988 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Google Tag Manager costs a phone 0 ms of main-thread work and 309 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 197 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 200 ms).

5 long tasks block the main thread while loading, the longest for 120 ms. During a long task the page ignores taps.

Polyfills for old browsers add 31 KiB JavaScript that modern phones do not need.

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.

2 KiB could be saved by minifying CSS.

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 34.3 s. Good is under 3.8 s.

The first text or image appears after 3.3 s on a phone. Good is under 1.8 s.

Real visitors wait 2.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Visually, the page fills in at 5.6 s (Speed Index). Good is under 3.4 s.

Your largest element takes 3.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We use cookies to personalise content and ads, to provide s…”. Most of its time is element render delay (2.3 s).

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 91 ms to 96 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 3.2 s to 3.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 20.9 MB in 222 requests on a phone: media 11.6 MB (4), images 5.9 MB (25) and scripts 3.1 MB (169). Under 2 MB keeps phones on slow connections fast.

3 images weigh 4.6 MB together. On a phone connection a single image that size takes seconds.

3 images are downloaded at several times the size a phone draws them, for example Section4-Corrosion.webp at 1,200 px wide, shown at 98 px. Resized copies would save about 330 KiB.

6 images further down the page (465 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 5.92 g of CO₂e: 710.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 dropdown has no label.

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

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

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

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

The homepage links to 158 pages on atslab.com and 6 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

/solutions, /calibration, /engineering, /forensics, /inspection and /testing-and-analysis and 2 others have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 6 pages by a URL that isn't their canonical one, for example /calibration, whose canonical is /calibration/%EF%BF%BDtegory%. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/training/reliability took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 141 found) and read each the way a search engine does.

4 of 11 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

6 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

Large scripts ship without source maps.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

atslab.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

atslab.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

Social proof on the homepage: 1 testimonial or review block. Pairing it with named testimonials or customer logos makes it far more convincing.

Your longest form asks for 44 fields (21 required). Every extra field lowers completion.

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 532 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

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.

Opening the homepage sets 1 cookie (measured from a US location before any click).

Loading the homepage contacts 14 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
