advancedtech.com website review

24 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.9 s.

About 359 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.4 s faster on a phone.

25 files are served with short cache lifetimes, so returning visitors download them again (325 KiB).

Your mobile performance score is 45 (desktop: 73). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google Tag Manager, Facebook and osano.com and others), adding 1.1 MB and 997 ms of main-thread time.

Google Tag Manager costs a phone 307 ms of main-thread work and 536 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.

Polyfills for old browsers add 29 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

9 long tasks block the main thread while loading, the longest for 152 ms. During a long task the page ignores taps.

About 22 KiB of CSS is downloaded but never applied on this page.

Desktop scores 73 but mobile only 45. A gap that wide usually means heavy scripts and images that hit phones hardest.

8 KiB could be saved by minifying JavaScript.

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

The page becomes fully interactive after 22.4 s. Good is under 3.8 s.

The first text or image appears after 4.5 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 8.7 s (Speed Index). Good is under 3.4 s.

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

Scripts block taps and scrolling for 515 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 171 ms to 201 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 3.1 s to 3.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.7 MB in 133 requests on a phone: scripts 1.2 MB (49), fonts 1.2 MB (6) and images 192 KiB (27). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.76 g of CO₂e: 91.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA attributes must conform to valid values: 1 element on the page fails this check, rated critical by axe-core.

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

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

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

Headings skip levels (h1 → h6, h2 → h6 and h2 → h4), which makes the page harder to scan with a screen reader.

The homepage links to 128 pages on advancedtech.com and 8 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.

We fetched 15 pages linked from your homepage (of 58 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Uncaught (in promise) Error: Qualified: invalid visitor state”.

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

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

1 link go through two or more redirects, for example https://instagram.com/advancedtechnologyservicesinc.

X-XSS-Protection is set to “1; mode=block;”; the header is deprecated and can introduce bugs. Use 0 or remove it.

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

advancedtech.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.

advancedtech.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.

Social proof on the homepage: 7 customer or partner logos. Pairing it with named testimonials or customer logos makes it far more convincing.

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 791 words of visible text.

Your SPF record doesn't end in -all or ~all, so it doesn't stop other servers sending as you: “v=spf1 redirect=8x70cfiz._spf._d.mim.ec”.

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 (Osano) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 7 cookies (measured from a US location before any click).

Loading the homepage contacts 13 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
