acdlabs.com website review

About 758 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.5 s faster on a phone.

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

Your mobile performance score is 53. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, Google CDN and Clarity and others), adding 1.5 MB and 839 ms of main-thread time.

About 173 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 710 ms faster on a phone.

8 images could be 537 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Google Tag Manager costs a phone 434 ms of main-thread work and 545 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.

Google CDN costs a phone 291 ms of main-thread work and 741 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.

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

168 KiB could be saved by minifying JavaScript.

12 long tasks block the main thread while loading, the longest for 122 ms. During a long task the page ignores taps.

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

17 KiB could be saved by minifying CSS.

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.

Real visitors see the first content after 3.0 s (75th percentile). Good is under 1.8 s.

The first text or image appears after 7.1 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 18.2 s. Good is under 3.8 s.

Your largest element takes 7.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “This web site is being migrated and pages will be redirecte…”.

Visually, the page fills in at 9.9 s (Speed Index). Good is under 3.4 s.

Real visitors wait 3.2 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 378 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

For real visitors the layout shifts by 0.11 (75th percentile). Good is under 0.1.

Real visitors wait 1.3 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 226 ms in total while the page loads. Good is under 200 ms.

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

Your homepage downloads 6.6 MB in 103 requests on a phone: media 2.5 MB (2), images 1.6 MB (24) and scripts 1.6 MB (36). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.86 g of CO₂e: 223.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

<svg> elements with an img or image role must have alternative text: 9 elements on the page fail this check, rated serious by axe-core.

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

5 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.

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

Headings skip levels (h1 → h4, h2 → h5 and h2 → h5), which makes the page harder to scan with a screen reader.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 178 pages on acdlabs.com and 11 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.

/solutions and /technical-support have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 119 found) and read each the way a search engine does.

6 of 13 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 403 ()”.

http://acdlabs.com does not redirect to https, so some visitors land on the insecure version.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

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

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

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

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

acdlabs.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.

acdlabs.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.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

Social proof on the homepage: 13 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage shows no opening hours. If customers visit or call, show when.

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 1,006 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 Ads, Google Analytics, Google Tag Manager, LinkedIn Insight and Microsoft Clarity (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 27 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 25 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
