amx.com website review

14 files are served with short cache lifetimes, so returning visitors download them again (20.3 MB).

15 images could be 20.6 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 100.8 s faster on a phone.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 4.7 s.

About 730 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.6 s faster on a phone.

About 250 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.2 s faster on a phone.

7 third-party services load with your homepage (Google Tag Manager, harmanpro.com and jQuery CDN and others), adding 22.5 MB and 568 ms of main-thread time.

harmanpro.com costs a phone 125 ms of main-thread work and 22.0 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 53. Pages that score under 90 lose visitors before the first paint.

7 long tasks block the main thread while loading, the longest for 127 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

The HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.

Polyfills for old browsers add 8 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.

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 107.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “2025 Install Brochures”.

Visually, the page fills in at 22.4 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 107.5 s. Good is under 3.8 s.

The first text or image appears after 5.6 s on a phone. Good is under 1.8 s.

Real visitors wait 2.9 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.7 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.7 s for your server to start answering (75th percentile). Good is under 800 ms.

29 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 278 ms to 232 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 22.6 MB in 53 requests on a phone: images 21.0 MB (32), scripts 1.2 MB (11) and stylesheets 270 KiB (2). Under 2 MB keeps phones on slow connections fast.

6 images weigh 19.6 MB together. On a phone connection a single image that size takes seconds.

6 images are downloaded at several times the size a phone draws them, for example AMX_MU-3300_ProductPhoto_front_original_(1)_original.png at 8,272 px wide, shown at 290 px. Resized copies would save about 17.2 MB.

11 images (20.7 MB) 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.

AMX_MU-3300_ProductPhoto_front_original_(1)_original.png 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).

By the Sustainable Web Design model, a visit to your homepage emits about 6.40 g of CO₂e: 767.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 tap target is too small or too close together to hit reliably with a finger.

All page content should be contained by landmarks: 7 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

Alternative text of images should not be repeated as text: 8 elements on the page fail this check, rated minor by axe-core.

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

No meta description, so Google writes its own snippet from whatever text it finds.

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

Your title is 71 characters, so Google will cut it off around 60: “AMX Audio Video Control Systems | English (US) | Professional Solutions”.

38 links have no real href, so search engines can't follow them.

The homepage links to 176 pages on amx.com and 24 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.

/en-US/product_families/encoding-decoding, /en-US/product_families/n2600-series-4k60, /en-US/product_families/n2400-series-4k60, /en-US/product_families/n2300-series-4k30, /en-US/product_families/n1000-series-hd and /en-US/product_families/n3300-series-4k60 and 1 other have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 154 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://adn.harmanpro.com/assets/amx-56facf790bc9a9035cac790c03824a37c755074101001828fe85d…”.

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

Opening https://amx.com goes through 2 redirects before the homepage loads.

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.

amx.com is registered until Jan 2027. Make sure auto-renew is on and the card on file is current.

amx.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.

amx.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.

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

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.

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 651 words of visible text.

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, Google Tag Manager and HubSpot (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 7 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 15 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
