gnatus.com.br website review

About 769 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.9 s faster on a phone.

17 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.8 s.

Your mobile performance score is 44. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 5.8 s on main-thread work while loading, 2.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and Facebook and others), adding 2.0 MB and 1.6 s of main-thread time.

14 files are served with short cache lifetimes, so returning visitors download them again (538 KiB).

2 images could be 764 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 153 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.

Google CDN costs a phone 525 ms of main-thread work and 742 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 401 ms of main-thread work and 330 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 long tasks block the main thread while loading, the longest for 360 ms. During a long task the page ignores taps.

callpage.io costs a phone 131 ms of main-thread work and 368 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 40 KiB JavaScript that modern phones do not need. 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 150 ms).

18 KiB could be saved by minifying JavaScript.

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.

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 image “Home Page Produtos Odontológicos”.

The page becomes fully interactive after 21.6 s. Good is under 3.8 s.

Visually, the page fills in at 11.4 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 874 ms in total while the page loads. Good is under 200 ms.

Real visitors wait 3.2 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.2 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.6 s for your server to start answering (75th percentile). Good is under 800 ms.

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

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 153 ms to 176 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.6 s to 2.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.1 MB in 134 requests on a phone: scripts 2.0 MB (57), images 1.3 MB (14) and other files 501 KiB (43). Under 2 MB keeps phones on slow connections fast.

2 images (266 KiB) 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.

By the Sustainable Web Design model, a visit to your homepage emits about 1.16 g of CO₂e: 139.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 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: 3 elements on the page fail this check, rated moderate by axe-core.

Main landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one main 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.

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

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

Alternative text of images should not be repeated as text: 9 elements on the page fail this check, rated minor by axe-core.

Headings should not be empty: 5 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h1 → h4 and h2 → h5), which makes the page harder to scan with a screen reader.

Elements with visible text labels do not have matching accessible names. (1 element).

The homepage links to 147 pages on gnatus.com.br and 18 external pages.

We fetched 15 pages linked from your homepage (of 66 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 401 ()”.

3 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

1 link go through two or more redirects, for example https://www.gnatus.com.br/equipamento-odontologico/equipamentos/biosseguranca/camaras-de-cons/.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

gnatus.com.br has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

gnatus.com.br's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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.

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.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

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.

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 859 words of visible text.

DMARC is set to p=none, so mail pretending to be gnatus.com.br is still delivered. Reports are on, so moving to quarantine is the next step.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Microsoft Clarity and 1 more (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 28 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 31 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
