lab.fi website review

Your mobile performance score is 86. Pages that score under 90 lose visitors before the first paint.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 800 ms.

2 images could be 82 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 650 ms faster on a phone.

18 files are served with short cache lifetimes, so returning visitors download them again (77 KiB).

About 36 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.

1 long task block the main thread while loading, the longest for 90 ms. During a long task the page ignores taps.

3 third-party services load with your homepage (piwik.pro, JSDelivr CDN and Google Fonts), adding 234 KiB and 66 ms of main-thread time.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

About 27 KiB of JavaScript is downloaded but never used 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.

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.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.1 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 834 ms for your server to start answering (75th percentile). Good is under 800 ms.

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 “Student of LAB University of Applied Sciences.”.

The page becomes fully interactive after 3.9 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 120 ms to 128 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

5 images further down the page (195 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.20 g of CO₂e: 23.5 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: 8 elements on the page fail this check, rated moderate by axe-core.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

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), so links shared on LinkedIn, Slack or Facebook show no preview picture.

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

The homepage links to 104 pages on lab.fi and 11 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://lab.fi/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.

We fetched 15 pages linked from your homepage (of 61 found) and read each the way a search engine does.

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 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.

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 575 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.

Loading the homepage contacts 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
