aertech.com website review

28 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.5 s.

7 files are served with short cache lifetimes, so returning visitors download them again (129 KiB).

Your mobile performance score is 40 (desktop: 91). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (hsappstatic.net, Google Tag Manager and Hubspot and others), adding 1.5 MB and 1.4 s of main-thread time.

About 589 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 900 ms faster on a phone.

hsappstatic.net costs a phone 638 ms of main-thread work and 694 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 Tag Manager costs a phone 499 ms of main-thread work and 467 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.

14 long tasks block the main thread while loading, the longest for 495 ms. During a long task the page ignores taps.

3 images could be 303 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

A phone's processor spends 3.9 s on main-thread work while loading, 2.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Polyfills for old browsers add 27 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

About 31 KiB of CSS is downloaded but never applied on this page.

Desktop scores 91 but mobile only 40. A gap that wide usually means heavy scripts and images that hit phones hardest.

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 12.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “2022-04-26-aer-brand-promo-08-youtube-2022-05-04-10-39-33-s…”.

The first text or image appears after 6.5 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 16.7 s. Good is under 3.8 s.

Visually, the page fills in at 7.6 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 727 ms in total while the page loads. Good is under 200 ms.

15 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 2.5 MB in 120 requests on a phone: scripts 1.5 MB (44), images 624 KiB (23) and fonts 222 KiB (8). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.71 g of CO₂e: 85.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

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

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

Your meta description is 234 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 80 pages on aertech.com and 14 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.

Your homepage links to /pcb-rework, which answers with an error. Visitors hit a dead end and search engines drop it.

/electronics-remanufacturing and /electronics-lifecycle-management-plm use the same meta description. A description written for each page earns more clicks.

/nashville, /quality, /history, /electronics-remanufacturing, /test-engineering and /electronics-lifecycle-management-plm and 4 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 24 found) and read each the way a search engine does.

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

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

Chrome logged issues while loading the page (“Cookie”).

1 link from your homepage to your own site is broken, for example https://aertech.com/pcb-rework/ (404).

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.

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.

1 link go through two or more redirects, for example http://dealers.aertech.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.

aertech.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.

aertech.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.

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

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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

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 753 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 and HubSpot (measured from a US location before any click). A consent tool (HubSpot cookie banner) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 10 cookies (measured from a US location before any click).

Loading the homepage contacts 21 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
