istao.it website review

118 files are served with short cache lifetimes, so returning visitors download them again (3.4 MB).

23 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.5 s.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 1.4 s).

12 images could be 493 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 550 ms faster on a phone.

Your mobile performance score is 77 (desktop: 82). Pages that score under 90 lose visitors before the first paint.

A phone's processor spends 2.7 s on main-thread work while loading, 792 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 50 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

About 181 KiB of JavaScript is downloaded but never used on this page.

2 third-party services load with your homepage (iubenda and Google Fonts), adding 210 KiB and 60 ms of main-thread time.

Polyfills for old browsers add 23 KiB JavaScript that modern phones do not need.

10 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Visually, the page fills in at 7.2 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.9 s on a phone. Good is under 1.8 s.

Your largest element takes 3.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

25 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 90 ms to 103 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.6 MB in 131 requests on a phone: images 2.8 MB (70), scripts 437 KiB (24) and fonts 233 KiB (6). Under 2 MB keeps phones on slow connections fast.

12 images (862 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.

7 images further down the page (372 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.03 g of CO₂e: 123.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

28 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

1 element hidden from screen readers can still receive keyboard focus.

1 link inside paragraphs relies on colour alone to stand out.

15 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 32 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.

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.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

5 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.

Headings skip levels (h1 → h3, h4 → h6 and h1 → h3), which makes the page harder to scan with a screen reader.

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

Your title is only 12 characters: “Home - ISTAO”. Between 30 and 65 characters leaves room to say what you do and for whom.

There are 2 <h1> headlines (“NEWS” and “I numeri ISTAO”). One clear main headline is easier for people and search engines.

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

4 links have no real href, so search engines can't follow them.

The homepage links to 68 pages on istao.it and 14 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://istao.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://istao.it/dalla-fondazione, https://istao.it/organi-statutari, https://istao.it/presidente, https://istao.it/organigramma, https://istao.it/essere-soci and https://istao.it/villa-favorita 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 48 found) and read each the way a search engine does.

2 of 9 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 image is served at too low a resolution for sharp phone screens.

Chrome logged issues while loading the page (“Mixed content”).

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: 47 customer or partner logos. 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.

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

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 476 words of visible text.

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

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