serlinolab.it website review

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

Your mobile performance score is 64. Pages that score under 90 lose visitors before the first paint.

About 279 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 470 ms faster on a phone.

8 third-party services load with your homepage (Clarity, alia-prod.com and Shopify and others), adding 1.6 MB and 507 ms of main-thread time.

19 files are served with short cache lifetimes, so returning visitors download them again (261 KiB).

About 62 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 310 ms faster on a phone.

A phone's processor spends 3.3 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 2,703 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Shopify costs a phone 62 ms of main-thread work and 967 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 long tasks block the main thread while loading, the longest for 83 ms. During a long task the page ignores taps.

Polyfills for old browsers add 39 KiB JavaScript that modern phones do not need.

1 image could be 9 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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.

Real visitors wait 604 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Your largest element takes 17.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 25.4 s. Good is under 3.8 s.

Visually, the page fills in at 8.2 s (Speed Index). Good is under 3.4 s.

Real visitors wait 3.5 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 232 ms to 286 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The first text or image appears after 2.4 s on a phone. Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 2.2 s to 2.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.4 MB in 298 requests on a phone: fonts 1.8 MB (9), scripts 1.2 MB (132) and other files 882 KiB (127). Under 2 MB keeps phones on slow connections fast.

square-web_optimized_434b56ea-ab13-4455-82a6-7f7877006834.we weighs 1,017 KiB. On a phone connection a single image that size takes seconds.

4 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.

1 image further down the page (1,017 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.23 g of CO₂e: 148.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

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

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

Your meta description is 231 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 38 pages on serlinolab.it and 6 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description 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.

https://serlinolab.it/pages/storia-del-serlinolab, https://serlinolab.it/policies/privacy-policy and https://serlinolab.it/policies/terms-of-service have no meta description, so Google writes the search snippet from whatever text it finds.

https://serlinolab.it/products/kit-completo-uomo, https://serlinolab.it/products/skincare-set-definitivo, https://serlinolab.it/products/kit-maxi, https://serlinolab.it/products/kit-giorno-notte, https://serlinolab.it/pages/storia-del-serlinolab and https://serlinolab.it/products/crema-viso-anti-eta-abbonamento and 3 others have no <h1> headline, so visitors and search engines get no clear main topic.

https://serlinolab.it/products/kit-completo-uomo, https://serlinolab.it/products/skincare-set-definitivo, https://serlinolab.it/products/kit-maxi, https://serlinolab.it/products/kit-giorno-notte, https://serlinolab.it/products/crema-viso-anti-eta-abbonamento and https://serlinolab.it/products/contorno-occhi-abbonamento have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage (of 17 found) and read each the way a search engine does.

4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_SOCKET_NOT_CONNECTED”.

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 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 612 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 3 mores (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 28 cookies, 1 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 52 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
