Compare side by sideOne score from every part of this review. How it works
Speed
1 third-party service on the page
1 third-party service load with your homepage (Cloudflare), adding 10 KiB and 10 ms of main-thread time.
Legacy JavaScript
10 KiBPolyfills for old browsers add 10 KiB JavaScript that modern phones do not need.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.
Use efficient cache lifetimes
4 KiB1 file is served with short cache lifetimes, so returning visitors download them again (4 KiB).

Mobile performance score: 100
100/100Your mobile performance score is 100. That is in Google's “good” band (90 and up).
Main-thread work: 0.1 s
A phone's processor spends 0.1 s on main-thread work while loading, 16 ms of it running JavaScript. That is comfortably low.
Server response: 2 ms
2 msYour server sent the HTML in 2 ms, well inside Google's 600 ms guideline.
Core Web Vitals
Not enough real-visitor data yet
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.
6 checks passed

First Contentful Paint: 0.8 s

Images and page weight
About 0.01 g of CO₂ per visit
0.01 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.01 g of CO₂e: 0.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
1 checks passed
Page weight: 19 KiB in 3 requests
19 KiBYour homepage downloads 19 KiB in 3 requests on a phone: scripts 10 KiB (1), HTML 8 KiB (1) and other files 1 KiB (1). That is a lean page.
Accessibility
49 text elements with low contrast
49 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
No main landmark
The page has no <main> landmark, so screen-reader users cannot jump straight to the content.
All page content should be contained by landmarks (1 element)
All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.
1 checks passed
26 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 29 WCAG 2.2 A/AA and best-practice rules on the phone render: 26 passed and 3 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
No social preview image
No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.
No X (Twitter) card tag
No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 48 pages on dotnetwork.com.br and 0 external pages.

Served over HTTPS
The homepage is served over HTTPS (dotnetwork.com.br).
Valid certificate (33 days left)
The certificate from Google Trust Services · WE1 verifies for dotnetwork.com.br and is valid for another 33 days.
http:// redirects to https
http://dotnetwork.com.br redirects to the secure version.
HTTP/2 and HTTP/3

All 40 links work
All 40 links checked from your homepage (40 internal, 0 external) answered without errors; 15 did not answer within 5 s.
Domain and trust
DNSSEC is off
dotnetwork.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.
3 checks passed
Domain is 2 years old
2 yearsdotnetwork.com.br was registered in Jan 2024. An established domain carries more trust with email providers and search engines.
Certificate issuers are restricted
CAA records allow only ssl.com, pki.goog, comodoca.com and letsencrypt.org to issue certificates for dotnetwork.com.br, so a mis-issued certificate from anyone else is refused.
Registered until Jan 2028
dotnetwork.com.br is registered until Jan 2028.
Content and conversion
No call to action on the first screen
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 calls to action
We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.
No social proof
No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.
No direct contact details
No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.
No form on the homepage
There is no form on the homepage, so every lead has to click through to another page first.
No risk reducer
No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
