tannico.nl website review

A phone's processor spends 5.4 s on main-thread work while loading, 2.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,556 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 73. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Shopify, posthog.com and Klaviyo and others), adding 2.3 MB and 650 ms of main-thread time.

About 545 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 650 ms.

Shopify costs a phone 283 ms of main-thread work and 1.3 MB 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.

16 files are served with short cache lifetimes, so returning visitors download them again (355 KiB).

Klaviyo costs a phone 101 ms of main-thread work and 322 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 80 ms. During a long task the page ignores taps.

About 51 KiB of CSS is downloaded but never applied on this page.

1 image could be 45 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 44 KiB JavaScript that modern phones do not need.

27 KiB could be saved by minifying JavaScript.

17 KiB JavaScript is shipped twice across bundles.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

2 KiB could be saved by minifying CSS.

The page becomes fully interactive after 19.4 s. Good is under 3.8 s.

Visually, the page fills in at 9.3 s (Speed Index). Good is under 3.4 s.

Your largest element takes 4.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “€ 30 korting op alles”.

1 image 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' tap response (inp) went from 111 ms to 113 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.5 s to 1.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.3 MB in 587 requests on a phone: scripts 1.8 MB (180), other files 1.7 MB (340) and fonts 318 KiB (3). Under 2 MB keeps phones on slow connections fast.

w46-natale-com.jpg 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 1.22 g of CO₂e: 146.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 tap target is 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.

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

Structured data found (Organization and WebSite) but with 1 problem, for example “Organization: url points at a different host (https://www.tannico.it)”.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 665 pages on tannico.nl and 7 external pages.

https://www.tannico.nl/en is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

We fetched 15 pages linked from your homepage (of 196 found) and read each the way a search engine does.

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

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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.

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.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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 382 words of visible text.

Before a visitor clicks anything, the page loads Criteo, Google Ads, Google Analytics, Google Tag Manager and Klaviyo and 3 mores (measured from a US location before any click). A consent tool (iubenda) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 27 cookies (measured from a US location before any click).

Loading the homepage contacts 43 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
