tnsi.com website review

19 images could be 1.7 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 2.4 s faster on a phone.

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.5 s.

About 674 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

Your mobile performance score is 56 (desktop: 63). Pages that score under 90 lose visitors before the first paint.

About 172 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and Optanon and others), adding 1.5 MB and 605 ms of main-thread time.

16 files are served with short cache lifetimes, so returning visitors download them again (157 KiB).

Google CDN costs a phone 233 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.

Google Tag Manager costs a phone 229 ms of main-thread work and 375 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.

A phone's processor spends 2.2 s on main-thread work while loading, 1.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 1,782 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

25 KiB could be saved by minifying JavaScript.

14 KiB could be saved by minifying CSS.

7 long tasks block the main thread while loading, the longest for 131 ms. During a long task the page ignores taps.

Polyfills for old browsers add 9 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.

The page becomes fully interactive after 22.3 s. Good is under 3.8 s.

Your largest element takes 7.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Infrastructure-as-a-Service to Enable Mission-Critical Tran…”.

The first text or image appears after 3.8 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 1.9 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.2 s for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 5.6 s (Speed Index). Good is under 3.4 s.

The layout shifts by 0.151 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 130 ms to 137 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 2.4 s to 2.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.3 MB in 142 requests on a phone: images 2.8 MB (44), scripts 1.6 MB (35) and other files 419 KiB (38). Under 2 MB keeps phones on slow connections fast.

15 images (2.5 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.

13 images further down the page (1.6 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

5 images are downloaded at several times the size a phone draws them, for example data-flow-min2.jpeg at 1,366 px wide, shown at 390 px. Resized copies would save about 445 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.50 g of CO₂e: 179.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

All page content should be contained by landmarks: 21 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.

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

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

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h1 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.

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

Structured data found (Corporation and SiteNavigationElement) but with 1 problem, for example “Corporation: sameAs is an empty list”.

The homepage links to 214 pages on tnsi.com and 147 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://tnsi.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.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://tnsi.com/tns-acquires-netnumber-press-release, whose canonical is https://tnsi.com/resource/com/tns-acquires-netnumber-press-release. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 99 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://id.rlcdn.com/464526.gif.

18 of 32 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

3 errors were logged to the browser console while the page loaded, for example “Error with Permissions-Policy header: Parse of permissions policy failed because of errors reported by structured heade…”.

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 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 912 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and The Trade Desk (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 12 cookies, 3 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 32 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
