semantix.com website review

About 665 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.9 s faster on a phone.

The page has 3,098 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 63. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and Other Google APIs/SDKs and others), adding 2.2 MB and 592 ms of main-thread time.

Google CDN costs a phone 415 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.

About 63 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

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

17 KiB could be saved by minifying JavaScript.

A phone's processor spends 2.4 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

site.com costs a phone 12 ms of main-thread work and 657 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.

15 files are served with short cache lifetimes, so returning visitors download them again (130 KiB).

14 KiB could be saved by minifying CSS.

9 long tasks block the main thread while loading, the longest for 103 ms. During a long task the page ignores taps.

Polyfills for old browsers add 17 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 wait 4.2 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 3.3 s (75th percentile). Good is under 1.8 s.

Real visitors wait 2.4 s for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 12.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We and our business partners use technologies, including co…”.

The page becomes fully interactive after 18.2 s. Good is under 3.8 s.

Visually, the page fills in at 8.7 s (Speed Index). Good is under 3.4 s.

Real visitors wait 227 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

9 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 156 ms to 150 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 2.3 s to 2.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.3 MB in 83 requests on a phone: scripts 2.1 MB (35), other files 406 KiB (8) and images 370 KiB (22). Under 2 MB keeps phones on slow connections fast.

1 image (56 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 0.95 g of CO₂e: 113.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

<svg> elements with an img or image role must have alternative text: 1 element on the page fails this check, rated serious by axe-core.

Document should not have more than one banner landmark: 1 element on the page fails 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.

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

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

Elements marked as presentational should be consistently ignored: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h1 → h3, h2 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.

Structured data found (BreadcrumbList, Corporation, Organization and WebPage) but with 1 problem, for example “Organization: missing name”.

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

The homepage links to 177 pages on semantix.com and 4 external pages.

There is no /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 67 found) and read each the way a search engine does.

4 of 13 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://transperfect.my.site.com/ESWChatTeamENG1745842500139/assets/styles/bootstrap.min.c…”.

The homepage carries about 1,055 words of visible text.

Before a visitor clicks anything, the page loads 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.

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