sicma21.com website review

7 third-party services load with your homepage (Google Tag Manager, Facebook and Google Maps and others), adding 1.7 MB and 1.2 s of main-thread time.

Google Tag Manager costs a phone 891 ms of main-thread work and 1.3 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 1,003 KiB of JavaScript is downloaded but never used on this page.

Your mobile performance score is 69 (desktop: 64). Pages that score under 90 lose visitors before the first paint.

3 images could be 70 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 500 ms faster on a phone.

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.

25 files block the first paint until they finish downloading. Deferring or inlining them could save about 350 ms.

5 files are served with short cache lifetimes, so returning visitors download them again (293 KiB).

A phone's processor spends 2.9 s on main-thread work while loading, 1.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 1,565 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

15 long tasks block the main thread while loading, the longest for 233 ms. During a long task the page ignores taps.

Polyfills for old browsers add 30 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.

Real visitors see the first content after 3.0 s (75th percentile). Good is under 1.8 s.

Real visitors wait 2.1 s for your server to start answering (75th percentile). Good is under 800 ms.

The page becomes fully interactive after 16.6 s. Good is under 3.8 s.

Scripts block taps and scrolling for 710 ms in total while the page loads. Good is under 200 ms.

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

The first text or image appears after 2.7 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 4.8 s (Speed Index). Good is under 3.4 s.

Your largest element takes 3.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Soluciones globales para la mejora industrial”.

1 image have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 139 ms to 162 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 3.2 s to 3.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.4 MB in 142 requests on a phone: scripts 1.9 MB (60), fonts 192 KiB (6) and images 176 KiB (6). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.69 g of CO₂e: 83.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 buttons have no accessible name, so screen readers announce just “button”.

11 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: 8 elements on the page fail this check, rated moderate by axe-core.

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.

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

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

ARIA role should be appropriate for the element: 2 elements on the page fail this check, rated minor by axe-core.

Elements marked as presentational should be consistently ignored: 2 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h3 → h6), 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.

The homepage links to 129 pages on sicma21.com and 11 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.sicma21.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 (of 38 found) and read each the way a search engine does.

9 of 28 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 image is served at too low a resolution for sharp phone screens.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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

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 768 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Meta Pixel (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 7 cookies (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.
