marsint.com website review

71 files are served with short cache lifetimes, so returning visitors download them again (3.8 MB).

5 images could be 2.3 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 4.3 s faster on a phone.

35 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.5 s.

Your mobile performance score is 48 (desktop: 87). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

7 third-party services load with your homepage (Google CDN, YouTube and Google Tag Manager and others), adding 2.5 MB and 1.3 s of main-thread time.

About 1.2 MB of JavaScript is downloaded but never used on this page.

Google CDN costs a phone 546 ms of main-thread work and 1.1 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.

YouTube costs a phone 472 ms of main-thread work and 979 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 3.3 s on main-thread work while loading, 1.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 157 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 200 ms).

14 long tasks block the main thread while loading, the longest for 193 ms. During a long task the page ignores taps.

Desktop scores 87 but mobile only 48. 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.

Your largest element takes 11.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Expert Designers and Manufacturer of Mechanical and Electri…”. Most of its time is resource load delay (5.6 s).

Visually, the page fills in at 16.7 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 29.5 s. Good is under 3.8 s.

Scripts block taps and scrolling for 521 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.6 s on a phone. Good is under 1.8 s.

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 6.7 MB in 109 requests on a phone: images 3.3 MB (13), scripts 2.3 MB (39) and fonts 364 KiB (6). Under 2 MB keeps phones on slow connections fast.

engineers-1.png weighs 584 KiB. On a phone connection a single image that size takes seconds.

1 image (584 KiB) is 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.

By the Sustainable Web Design model, a visit to your homepage emits about 1.90 g of CO₂e: 227.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 dropdown has no label.

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

Form elements should have a visible label: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 15 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.

4 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.

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

There are 2 <h1> headlines (“Electronics Manufacturing and Product Design” and “Expert Designers and Manufacturer of Mechanical a…”). One clear main headline is easier for people and search engines.

The homepage links to 34 pages on marsint.com and 8 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://www.marsint.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.

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

5 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

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

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

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.

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.

The homepage carries about 499 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics and Google Tag Manager (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 4 cookies, 1 of them by other companies (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 13 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
