ttl.fi website review

Your mobile performance score is 79 (desktop: 96). Pages that score under 90 lose visitors before the first paint.

About 140 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 750 ms faster on a phone.

27 files are served with short cache lifetimes, so returning visitors download them again (131 KiB).

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

About 83 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 280 ms faster on a phone.

3 third-party services load with your homepage (cookiepro.com, Matomo and Cloudflare CDN), adding 298 KiB and 154 ms of main-thread time.

Polyfills for old browsers add 9 KiB JavaScript that modern phones do not need. 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 60 ms. During a long task the page ignores taps.

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

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 “Naisoletettu hymyil”.

The page becomes fully interactive after 5.0 s. Good is under 3.8 s.

The first text or image appears after 2.1 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 3.8 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.2 s to 1.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

By the Sustainable Web Design model, a visit to your homepage emits about 0.26 g of CO₂e: 31.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Structured data found (Organization, WebPage and WebSite) but with 1 problem, for example “WebPage: breadcrumb is an empty list”.

The homepage links to 164 pages on ttl.fi and 5 external pages.

There is no https://www.ttl.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.

Your homepage links to https://www.ttl.fi/node/883ec687-c4c8-42bc-9f9b-f5a62f7f8d73, which answers with an error. Visitors hit a dead end and search engines drop it.

https://www.ttl.fi/tutkimus/hankkeet has no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://www.ttl.fi/tutkimus/hankkeet, whose canonical is https://www.ttl.fi/en/research/projects. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 136 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.

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 273 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 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
