ztsystems.com website review

7 images could be 3.3 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 3.0 s faster on a phone.

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

Your mobile performance score is 68. Pages that score under 90 lose visitors before the first paint.

About 444 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

7 third-party services load with your homepage (Google CDN, Cloudflare CDN and Google Tag Manager and others), adding 1.0 MB and 471 ms of main-thread time.

About 72 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

Google CDN costs a phone 282 ms of main-thread work and 734 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.

5 long tasks block the main thread while loading, the longest for 89 ms. During a long task the page ignores taps.

2 files are served with short cache lifetimes, so returning visitors download them again (50 KiB).

Polyfills for old browsers add 10 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 9.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Sanmina-ZT-Hero-Image-10-27-25”.

The page becomes fully interactive after 14.8 s. Good is under 3.8 s.

Visually, the page fills in at 6.2 s (Speed Index). Good is under 3.4 s.

Real visitors wait 830 ms for your server to start answering (75th percentile). Good is under 800 ms.

1 image 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 71 ms to 70 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.2 MB in 68 requests on a phone: images 4.0 MB (22), scripts 1,017 KiB (21) and fonts 654 KiB (7). Under 2 MB keeps phones on slow connections fast.

2 images weigh 2.4 MB together. On a phone connection a single image that size takes seconds.

5 images are downloaded at several times the size a phone draws them, for example 2021028jkd_JC_0007_f.jpg at 2,500 px wide, shown at 300 px. Resized copies would save about 2.6 MB.

7 images (3.5 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.

4 images further down the page (2.9 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

about-sec-bg.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).

By the Sustainable Web Design model, a visit to your homepage emits about 1.75 g of CO₂e: 209.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must be contained by particular parents: 12 elements on the page fail this check, rated critical by axe-core.

1 button has no accessible name, so screen readers announce just “button”.

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

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

1 element hidden from screen readers can still receive keyboard focus.

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 18 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.

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.

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

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

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

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

The homepage links to 35 pages on ztsystems.com and 10 external pages.

Your Organization JSON-LD is missing 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.

There is no https://ztsystems.com/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.

https://ztsystems.com/job-listing has no <title>, so Google invents the link text in results.

https://ztsystems.com/sanmina-completes-acquisition-of-zt-systems-data-center-infrastructure-manufacturing-business-from-amd, https://ztsystems.com/amd-to-significantly-expand-data-center-ai-systems-capabilities-with-acquisition-of-hyperscale-solutions-provider-zt-systems, https://ztsystems.com/zt-systems-announces-acx200-solutions, https://ztsystems.com/csr and https://ztsystems.com/privacy-policy have no meta description, so Google writes the search snippet from whatever text it finds.

https://ztsystems.com/job-listing has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage and read each the way a search engine does.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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 402 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager (measured from a US location before any click). A consent tool (CookieYes) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 2 cookies (measured from a US location before any click).

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