leonardodavinci.it website review

About 188 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 900 ms faster on a phone.

Your mobile performance score is 71 (desktop: 93). Pages that score under 90 lose visitors before the first paint.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 800 ms.

Google Tag Manager costs a phone 310 ms of main-thread work and 311 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.

About 29 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

3 third-party services load with your homepage (Google Tag Manager, Cookiebot and Google Analytics), adding 466 KiB and 374 ms of main-thread time.

3 long tasks block the main thread while loading, the longest for 204 ms. During a long task the page ignores taps.

1 file is served with short cache lifetimes, so returning visitors download them again (33 KiB).

7 KiB could be saved by minifying CSS.

6 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.

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 4.1 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 3.2 s (75th percentile). Good is under 1.8 s.

Real visitors wait 2.6 s for your server to start answering (75th percentile). Good is under 800 ms.

The page becomes fully interactive after 13.3 s. Good is under 3.8 s.

Your largest element takes 5.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Utilizziamo i cookie per personalizzare contenuti ed annunc…”. Most of its time is element render delay (3.7 s).

Visually, the page fills in at 6.6 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 136 ms to 151 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 3.9 s to 4.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 16.6 MB in 44 requests on a phone: media 12.1 MB (4), images 3.2 MB (22) and fonts 851 KiB (7). Under 2 MB keeps phones on slow connections fast.

1 image is downloaded at several times the size a phone draws it, for example Leonardo-da-Vinci_focusSANGIO-17-1.webp at 708 px wide, shown at 192 px. Resized copies would save about 29 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 4.71 g of CO₂e: 565.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 24 characters: “Home - Leonardo da Vinci”. Between 30 and 65 characters leaves room to say what you do and for whom.

No Open Graph image (also missing: og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://www.leonardodavinci.it/sitemap.xml, so Google discovers your pages only by following links.

The homepage links to 36 pages on leonardodavinci.it and 5 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://leonardodavinci.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://leonardodavinci.it/en and https://leonardodavinci.it/de all use the title “Home - Leonardo da Vinci”. Search engines can't tell which page to show for a search, so each competes with the others.

https://leonardodavinci.it/leonardo-wine-lover, https://leonardodavinci.it/sangiovese, https://leonardodavinci.it/impronta, https://leonardodavinci.it/taccuino, https://leonardodavinci.it/en and https://leonardodavinci.it/de and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 20 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Error with Permissions-Policy header: Parse of permissions policy failed because of errors reported by structured heade…”.

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.

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

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 679 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (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.

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

Loading the homepage contacts 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
