nsi-mi.com website review

147 files block the first paint until they finish downloading. Deferring or inlining them could save about 17.9 s.

About 662 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.0 s faster on a phone.

432 KiB could be saved by minifying CSS.

19 files are served with short cache lifetimes, so returning visitors download them again (751 KiB).

6 third-party services load with your homepage (Azure Web Services, Google Tag Manager and Optanon and others), adding 4.1 MB and 682 ms of main-thread time.

Your mobile performance score is 50. Pages that score under 90 lose visitors before the first paint.

Azure Web Services costs a phone 336 ms of main-thread work and 3.4 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.

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.

1 image could be 341 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Google Tag Manager costs a phone 188 ms of main-thread work and 301 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.

Polyfills for old browsers add 20 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

6 KiB could be saved by minifying JavaScript.

7 long tasks block the main thread while loading, the longest for 100 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

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.

Real visitors wait 1.9 s for your server to start answering (75th percentile). Good is under 800 ms.

The first text or image appears after 12.5 s on a phone. Good is under 1.8 s.

Your largest element takes 23.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 24.0 s. Good is under 3.8 s.

Visually, the page fills in at 12.5 s (Speed Index). Good is under 3.4 s.

Real visitors wait 3.4 s for the largest content to appear (75th percentile). Good is under 2.5 s.

For real visitors the layout shifts by 0.14 (75th percentile). Good is under 0.1.

Real visitors see the first content after 2.9 s (75th percentile). Good is under 1.8 s.

The layout shifts by 0.146 while loading, so content jumps under the reader's thumb. Good is under 0.1.

7 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 88 ms to 89 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 3.9 s to 3.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.3 MB in 193 requests on a phone: stylesheets 2.1 MB (146), scripts 1.2 MB (20) and images 767 KiB (11). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.21 g of CO₂e: 145.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

Headings should not be empty: 8 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h2 → h4, h2 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.

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

Your title is only 19 characters: “NSI-MI Technologies”. 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.

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

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

No XML sitemap at https://www.edax.com/sitemap.xml, so Google discovers your pages only by following links.

7 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 185 pages on nsi-mi.com and 13 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.

https://www.nsi-mi.com/contact-us/request-for-info-or-quote, https://www.nsi-mi.com/applications, https://www.nsi-mi.com/applications/automotive, https://www.nsi-mi.com/applications/general-antenna-testing, https://www.nsi-mi.com/applications/precision-positioning and https://www.nsi-mi.com/system-solutions/far-field-systems/compact-range-systems/radome-measurement-systems and 9 others 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.

4 of 16 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

6 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://ametekcdn2.azureedge.net/-/media/base-themes/core-libraries/styles/mediaelementpla…”.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust 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 646 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

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

Opening the homepage sets 6 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.
