tannico.ch website review

A phone's processor spends 7.1 s on main-thread work while loading, 3.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,261 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Shopify, posthog.com and Klaviyo and others), adding 2.3 MB and 1.1 s of main-thread time.

Your mobile performance score is 65. Pages that score under 90 lose visitors before the first paint.

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.

Shopify costs a phone 507 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.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 600 ms.

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

Klaviyo costs a phone 149 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.

About 51 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.

16 long tasks block the main thread while loading, the longest for 118 ms. During a long task the page ignores taps.

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.

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.

The page becomes fully interactive after 21.6 s. Good is under 3.8 s.

Visually, the page fills in at 8.3 s (Speed Index). Good is under 3.4 s.

Your largest element takes 4.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Ausgezeichnete Weine 2026”.

Scripts block taps and scrolling for 389 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.2 MB in 585 requests on a phone: scripts 1.8 MB (180), other files 1.7 MB (341) and fonts 318 KiB (3). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.18 g of CO₂e: 142.0 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.

Your meta description is 173 characters; Google truncates after about 160, so the end of your pitch is cut.

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 622 pages on tannico.ch and 7 external pages.

https://www.tannico.ch/en, https://www.tannico.ch/collections/selezione-permanente-biodinamici-e-naturali/sconto-attivo, https://www.tannico.ch/collections/vini-premiati-in-offerta, https://www.tannico.ch/collections/vini-vini-sotto-i-10-euro/sconto-attivo, https://www.tannico.ch/collections/selezioni-i-migliori-vini-sotto-i-20-euro/sconto-attivo and https://www.tannico.ch/collections/vini-vini-sotto-i-50-euro/sconto-attivo and 2 others are marked noindex but linked from your homepage. If they are meant to be found, remove the noindex.

https://www.tannico.ch/collections/all-our-promo-2, https://www.tannico.ch/collections/selezione-permanente-biodinamici-e-naturali/sconto-attivo, https://www.tannico.ch/collections/vini-premiati-in-offerta, https://www.tannico.ch/collections/vini-vini-sotto-i-10-euro/sconto-attivo, https://www.tannico.ch/collections/selezioni-i-migliori-vini-sotto-i-20-euro/sconto-attivo and https://www.tannico.ch/collections/vini-vini-sotto-i-50-euro/sconto-attivo and 1 other have no <h1> headline, so visitors and search engines get no clear main topic.

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

15 of 34 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.

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 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 279 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 25 cookies (measured from a US location before any click).

Loading the homepage contacts 39 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
