americonplus.com website review

29 files are served with short cache lifetimes, so returning visitors download them again (571 KiB).

9 images could be 263 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.4 s faster on a phone.

27 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

Your mobile performance score is 64 (desktop: 81). Pages that score under 90 lose visitors before the first paint.

About 109 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

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

7 long tasks block the main thread while loading, the longest for 254 ms. During a long task the page ignores taps.

The page has 2,442 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 2.1 s on main-thread work while loading, 558 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 221 KiB of JavaScript is downloaded but never used on this page.

6 third-party services load with your homepage (51.la, bdstatic.com and 34.150.86.132 and others), adding 134 KiB and 33 ms of main-thread time.

11 KiB could be saved by minifying CSS.

11 KiB could be saved by minifying JavaScript.

Polyfills for old browsers add 7 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.

Your largest element takes 9.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “聚鑫汇”.

The page becomes fully interactive after 9.9 s. Good is under 3.8 s.

The first text or image appears after 3.6 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 5.4 s (Speed Index). Good is under 3.4 s.

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

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.

Your homepage downloads 3.6 MB in 95 requests on a phone: images 2.5 MB (52), scripts 534 KiB (22) and fonts 266 KiB (2). Under 2 MB keeps phones on slow connections fast.

bg5_new.jpg 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 zfzd_qrcode.png at 1,920 px wide, shown at 115 px. Resized copies would save about 118 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.01 g of CO₂e: 121.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 frame has no title, so screen-reader users cannot tell what it contains.

Some lists contain elements other than list items, which screen readers announce wrongly.

All page content should be contained by landmarks: 15 elements on the page fail this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

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

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

Your title is only 17 characters: “聚鑫汇-创新物联科技,点亮美好生活”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

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

The homepage links to 127 pages on americonplus.com and 18 external pages.

Your Organization JSON-LD is missing logo, 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.

/wisdom_life/smart_light_environment.html, /wisdom_life/smart_audio_visual.html, /wisdom_life/smart_security.html, /smart_management/smart_campus.html, /innovation_technology/innovating.html and /about.html and 9 others use the same meta description. A description written for each page earns more clicks.

/wisdom_life/smart_light_environment.html, /wisdom_life/smart_audio_visual.html, /wisdom_life/smart_security.html, /smart_management/smart_campus.html, /innovation_technology/innovating.html and /about.html and 9 others 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.

/service/contact.html and /investor/notice.html took over 3 s to send their HTML from our server.

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

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

2 images are served at too low a resolution for sharp phone screens.

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.

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.

americonplus.com was registered in Oct 2026 through Realtime Register B.V.. Spam filters and search engines treat brand-new domains more cautiously, so expect email and rankings to take a few months to settle.

americonplus.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.

americonplus.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.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 60 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.

americonplus.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.

americonplus.com has no SPF record, so mail servers can't tell which servers may send email as you. Your mail lands in spam more often, and anyone can send mail pretending to be you.

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.

americonplus.com has no MX record, so it receives no email. SPF -all and DMARC reject still matter: they stop others sending mail as you.

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.

Opening the homepage sets 4 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 7 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
