unoenergy.it website review

The page has 47,780 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 49. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

About 251 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 820 ms faster on a phone.

5 long tasks block the main thread while loading, the longest for 876 ms. During a long task the page ignores taps.

8 images could be 205 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

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.

cookiebot.eu costs a phone 111 ms of main-thread work and 320 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.

3 third-party services load with your homepage (cookiebot.eu, Google/Doubleclick Ads and Google Analytics), adding 322 KiB and 111 ms of main-thread time.

About 13 KiB of CSS is downloaded but never applied on this page.

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 8.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Sicuro 24”.

The first text or image appears after 3.8 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 8.9 s. Good is under 3.8 s.

Visually, the page fills in at 6.3 s (Speed Index). Good is under 3.4 s.

Real visitors wait 306 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Scripts block taps and scrolling for 525 ms in total while the page loads. Good is under 200 ms.

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

By the Sustainable Web Design model, a visit to your homepage emits about 0.38 g of CO₂e: 45.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 visible link has no text or label, so screen readers cannot say where it goes.

The homepage links to 69 pages on unoenergy.it and 25 external pages.

There is no https://www.unoenergy.it/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.

https://www.unoenergy.it/casa/luce/luce-sicuro-24 and https://www.unoenergy.it/casa/gas/casa-calore-sicuro-24 are marked noindex but linked from your homepage. If they are meant to be found, remove the noindex.

https://www.unoenergy.it/casa/luce/luce-sicuro-24 and https://www.unoenergy.it/casa/gas/casa-calore-sicuro-24 have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 53 found) and read each the way a search engine does.

Large scripts ship without source maps.

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 customer or partner logo. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 1,053 words of visible text.

Before a visitor clicks anything, the page loads Google Ads and Google Analytics (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Loading the homepage contacts 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
