siaemic.com website review

72 files are served with short cache lifetimes, so returning visitors download them again (10.8 MB).

36 images could be 7.5 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 7.5 s faster on a phone.

18 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.6 s.

Your mobile performance score is 61 (desktop: 63). Pages that score under 90 lose visitors before the first paint.

About 21 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 120 ms faster on a phone.

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.

2 KiB could be saved by minifying CSS.

Your largest element takes 12.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “MOBILE”. Most of its time is resource load delay (6.7 s).

Visually, the page fills in at 13.3 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 12.1 s. Good is under 3.8 s.

The first text or image appears after 2.8 s on a phone. Good is under 1.8 s.

29 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 96 ms to 88 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 2.6 s to 2.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 10.8 MB in 73 requests on a phone: images 10.6 MB (41), scripts 126 KiB (18) and stylesheets 47 KiB (13). Under 2 MB keeps phones on slow connections fast.

12 images weigh 7.6 MB together. On a phone connection a single image that size takes seconds.

18 images are downloaded at several times the size a phone draws them, for example 6_sfondo_per_apparati_e_scritte.png at 1,900 px wide, shown at 362 px. Resized copies would save about 5.5 MB.

22 images (9.5 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.

Mobile.png is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 3.07 g of CO₂e: 368.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

6 tap targets are too small or too close together to hit reliably with a finger.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

The robots meta tag says “noindex, nofollow”: Google is told not to list this page at all.

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

Google's crawler is blocked from indexing this page.

Your title is only 21 characters: “SIAE MICROELETTRONICA”. Between 30 and 65 characters leaves room to say what you do and for whom.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

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

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

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 164 pages on siaemic.com and 7 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://www.siaemic.com/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.

If they are meant to be found, remove the noindex.

We fetched 15 pages linked from your homepage (of 81 found) and read each the way a search engine does.

30 of 46 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

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.

The homepage shows no opening hours. If customers visit or call, show when.

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

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 624 words of visible text.

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

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.
