stemma.fi website review

13 images could be 267 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.0 s faster on a phone.

The page has 3,279 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 (Lucky Orange, Google Tag Manager and Klaviyo and others), adding 1.2 MB and 857 ms of main-thread time.

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

8 long tasks block the main thread while loading, the longest for 519 ms. During a long task the page ignores taps.

About 391 KiB of JavaScript is downloaded but never used on this page.

A phone's processor spends 3.7 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Lucky Orange costs a phone 347 ms of main-thread work and 103 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.

Google Tag Manager costs a phone 270 ms of main-thread work and 334 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.

Shopify costs a phone 30 ms of main-thread work and 394 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.

11 files are served with short cache lifetimes, so returning visitors download them again (30 KiB).

Polyfills for old browsers add 28 KiB JavaScript that modern phones do not need.

About 17 KiB of CSS is downloaded but never applied on this page.

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.

The page becomes fully interactive after 16.2 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 160 ms to 202 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your largest element takes 3.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Scripts block taps and scrolling for 458 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 4.8 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.3 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.2 MB in 266 requests on a phone: scripts 1.1 MB (71), images 1.0 MB (52) and other files 876 KiB (117). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.91 g of CO₂e: 109.5 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”.

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

Document should not have more than one banner landmark: 1 element on the page fails this check, rated moderate by axe-core.

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.

60 form fields have no label, so screen readers announce an empty box and autofill guesses.

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

Alternative text of images should not be repeated as text: 22 elements on the page fail this check, rated minor by axe-core.

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

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

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

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

The homepage links to 208 pages on stemma.fi and 4 external pages.

/pages/tuotemerkit has no meta description, so Google writes the search snippet from whatever text it finds.

/pages/stemma-paikallinen-verkkokauppasi has no <h1> headline, so visitors and search engines get no clear main topic.

/pages/maksutavat-ja-rahoitus, /pages/stemma-paikallinen-verkkokauppasi, /pages/tuotemerkit, /collections/nojatuolit, /products/lahjakortti-stemma-fi-verkkokauppaan and /collections/kotimaiset-tuotteet and 8 others took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 171 found) and read each the way a search engine does.

3 images failed to load on a phone, for example https://beacon.krxd.net/event.gif?event_id=OjlW6BOg&event_type=default&pixel_audience_id=ros.

41 of 101 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

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

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.

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 483 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and LinkedIn Insight and 2 mores (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 12 cookies, 2 of them by other companies (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.

Loading the homepage contacts 33 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
