h3.com website review

51 files are served with short cache lifetimes, so returning visitors download them again (2.4 MB).

3 images could be 1.5 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 3.9 s faster on a phone.

25 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.3 s.

Your mobile performance score is 67 (desktop: 93). Pages that score under 90 lose visitors before the first paint.

About 60 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 320 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 300 ms).

About 44 KiB of JavaScript is downloaded but never used on this page.

1 third-party service load with your homepage (cdn-cookieyes.com), adding 30 KiB and 24 ms of main-thread time.

Desktop scores 93 but mobile only 67. A gap that wide usually means heavy scripts and images that hit phones hardest.

Polyfills for old browsers add 9 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.

3 KiB could be saved by minifying CSS.

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

Your largest element takes 9.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 9.3 s. Good is under 3.8 s.

Visually, the page fills in at 6.1 s (Speed Index). Good is under 3.4 s.

Real visitors wait 2.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.7 s (75th percentile). Good is under 1.8 s.

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 90 ms to 90 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 2.5 s to 2.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

MOBILE-VERSAO-NOVA-754x1024.png weighs 907 KiB. On a phone connection a single image that size takes seconds.

Your homepage downloads 2.5 MB in 61 requests on a phone: images 2.1 MB (8), scripts 187 KiB (23) and stylesheets 103 KiB (22). Under 2 MB keeps phones on slow connections fast.

2 images (1.2 MB) 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 0.70 g of CO₂e: 84.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

8 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.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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

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

Your title is only 9 characters: “HOME - H3”. Between 30 and 65 characters leaves room to say what you do and for whom.

There are 2 <h1> headlines (“NOT SO FAST FOOD” and “TRUE FOOD”). One clear main headline is easier for people and search engines.

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

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 17 pages on h3.com and 8 external pages.

Your Organization JSON-LD is missing name, logo, sameAs (social profiles) 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 /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.

/ementa, /onde and /contactos have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 3 pages linked from your homepage and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_TUNNEL_CONNECTION_FAILED”.

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

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

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

h3.com 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.

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 analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

There is no form on the homepage, so every lead has to click through to another page first.

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 341 words of visible text.

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.

Opening the homepage sets 1 cookie (measured from a US location before any click).

Loading the homepage contacts 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
