adastec.com website review

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.8 s.

7 third-party services load with your homepage (website-files.com, Google Tag Manager and cloudfront.net and others), adding 12.6 MB and 363 ms of main-thread time.

website-files.com costs a phone 224 ms of main-thread work and 12.3 MB 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.

Your mobile performance score is 76 (desktop: 84). Pages that score under 90 lose visitors before the first paint.

4 long tasks block the main thread while loading, the longest for 184 ms. During a long task the page ignores taps.

About 29 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.

6 KiB could be saved by minifying CSS.

About 126 KiB of JavaScript is downloaded but never used on this page.

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

1 file is served with short cache lifetimes, so returning visitors download them again (2 KiB).

The page becomes fully interactive after 67.3 s. Good is under 3.8 s.

Visually, the page fills in at 11.9 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 0.9 s to 1.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your largest element takes 3.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “ADASTEC’s SAE Level-4 Automated Driving Software Platform e…”.

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

The first text or image appears after 2.4 s on a phone. Good is under 1.8 s.

Your homepage downloads 12.6 MB in 29 requests on a phone: other files 11.9 MB (5), scripts 363 KiB (9) and images 222 KiB (6). Under 2 MB keeps phones on slow connections fast.

602274a9649c994f0bf41578_Adastec_Logo_FeMale (1).svg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image is downloaded at several times the size a phone draws it, for example 600d67e9c5671b826d03cb8c_CIRCLE SEGMENT-08-p-500.png at 374 px wide, shown at 118 px. Resized copies would save about 5 KiB.

3 images (141 KiB) are 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.

3 images further down the page (141 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 3.58 g of CO₂e: 429.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 tap targets are too small or too close together to hit reliably with a finger.

<html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 11 elements on the page fail this check, rated moderate by axe-core.

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

The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is only 13 characters: “ADASTEC Corp.”. 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.

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

There is no robots.txt at adastec.com/robots.txt, the first file search crawlers ask for.

The homepage links to 11 pages on adastec.com and 18 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 /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.

/company-contact and /company-docs have no <h1> headline, so visitors and search engines get no clear main topic.

/photos, /company-contact and /company-docs 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 8 pages linked from your homepage and read each the way a search engine does.

1 link to other sites is dead, for example https://www.karsan.com/en (404).

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.

2 links go through two or more redirects, for example http://dutchautomatedmobility.com/.

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.

adastec.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.

adastec.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.

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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

Social proof on the homepage: 18 customer or partner logos. Pairing it with named testimonials or customer logos makes it far more convincing.

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

There is no form on the homepage, so every lead has to click through to another page first.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 278 words of visible text.

adastec.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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 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 3 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 8 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
