Speed

6 to fix62
  • Reduce unused JavaScript

    2.0 s · 247 KiB

    About 247 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.0 s faster on a phone.

  • Render-blocking requests

    2.0 s

    3 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.0 s.

  • 3,435 HTML elements

    The page has 3,435 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • Improve image delivery

    800 ms · 287 KiB

    5 images could be 287 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 800 ms faster on a phone.

  • Mobile performance score: 62

    62/100

    Your mobile performance score is 62 (desktop: 95). Pages that score under 90 lose visitors before the first paint.

  • Reduce unused CSS

    300 ms · 96 KiB

    About 96 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

  • 4 third-party services on the page

    4 third-party services load with your homepage (Google Tag Manager, zeppelin-group.com and VWO and others), adding 713 KiB and 431 ms of main-thread time.

  • Use efficient cache lifetimes

    150 ms · 40 KiB

    3 files are served with short cache lifetimes, so returning visitors download them again (40 KiB).

  • 6 long tasks on the main thread

    6 long tasks block the main thread while loading, the longest for 109 ms. During a long task the page ignores taps.

  • Phones get a much slower page than desktops

    Desktop scores 95 but mobile only 62. A gap that wide usually means heavy scripts and images that hit phones hardest.

  • Legacy JavaScript

    7 KiB

    Polyfills for old browsers add 7 KiB JavaScript that modern phones do not need.

  • Chained critical requests

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

  • Forced reflow

    Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

2 checks passed
  • Main-thread work: 1.1 s

    A phone's processor spends 1.1 s on main-thread work while loading, 443 ms of it running JavaScript. That is comfortably low.

  • Server response: 1 ms

    1 ms

    Your server sent the HTML in 1 ms, well inside Google's 600 ms guideline.

Core Web Vitals

9 to fix100
  • Fails Core Web Vitals for real visitors

    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.

  • Largest Contentful Paint: 8.9 s

    8.9 s

    Your largest element takes 8.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Experience windows anew.”.

  • Time to Interactive: 8.9 s

    8.9 s

    The page becomes fully interactive after 8.9 s. Good is under 3.8 s.

  • Largest content (LCP) got 53% slower for real visitors

    +53%

    Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 1.6 s to 2.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Real-user TTFB: 875 ms

    875 ms

    Real visitors wait 875 ms for your server to start answering (75th percentile). Good is under 800 ms.

  • First Contentful Paint: 2.9 s

    2.9 s

    The first text or image appears after 2.9 s on a phone. Good is under 1.8 s.

  • Speed Index: 4.6 s

    4.6 s

    Visually, the page fills in at 4.6 s (Speed Index). Good is under 3.4 s.

  • 15 images without width and height

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

  • Cumulative Layout Shift: 0.108

    0.108

    The layout shifts by 0.108 while loading, so content jumps under the reader's thumb. Good is under 0.1.

  • Tap response (INP) held steady for real visitors

    +6%

    Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 157 ms to 166 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

5 checks passed
  • Real-user LCP: 2.3 s

    2.3 s

    Real visitors wait 2.3 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Real-user INP: 164 ms

    164 ms

    Real visitors wait 164 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

  • Real-user CLS: 0.02

    0.02

    For real visitors the layout shifts by 0.02 (75th percentile). Good is under 0.1.

  • Real-user FCP: 1.6 s

    1.6 s

    Real visitors see the first content after 1.6 s (75th percentile). Good is under 1.8 s.

  • Total Blocking Time: 162 ms

    162 ms

    Scripts block the page for only 162 ms while loading. Good is under 200 ms.

Images and page weight

3 to fix73
  • 8 images in older formats

    8 images (576 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

  • 7 images below the first screen load straight away

    7 images further down the page (366 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

  • 1 image far larger than shown

    18 KiB

    1 image is downloaded at several times the size a phone draws it, for example finstral-check-kit-en-ebenen.png at 400 px wide, shown at 120 px. Resized copies would save about 18 KiB.

  • About 0.5 g of CO₂ per visit

    0.50 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.50 g of CO₂e: 59.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 checks passed
  • Page weight: 1.8 MB in 36 requests

    1.8 MB

    Your homepage downloads 1.8 MB in 36 requests on a phone: images 976 KiB (20), scripts 562 KiB (9) and other files 95 KiB (3). That is a lean page.

Accessibility

8 to fixGoogle 7888
  • Images must have alternative text (8 elements)

    Images must have alternative text: 8 elements on the page fail this check, rated critical by axe-core.

  • 9 text elements with low contrast

    9 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

  • <html> element must have a lang attribute (1 element)

    <html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.

  • Scrollable region must have keyboard access (1 element)

    Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

  • All page content should be contained by landmarks (72 elements)

    All page content should be contained by landmarks: 72 elements on the page fail this check, rated moderate by axe-core.

  • Zoom is disabled

    The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

  • 5 links without text

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

  • No page language

    The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

  • Headings skip levels

    Headings skip levels (h2 → h6), which makes the page harder to scan with a screen reader.

1 checks passed
  • 42 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 50 WCAG 2.2 A/AA and best-practice rules on the phone render: 42 passed and 8 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

6 to fixGoogle 6971
  • No meta description

    No meta description, so Google writes its own snippet from whatever text it finds.

  • No H1 headline

    There is no <h1>, so neither visitors nor Google get a clear main headline.

  • Structured data has 1 problem

    Structured data found (Organization and WebSite) but with 1 problem, for example “WebSite: missing name”.

  • No social preview image

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

  • 6 links crawlers can't follow

    6 links have no real href, so search engines can't follow them.

  • 5 links with vague text

    5 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

  • No X (Twitter) card tag

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

  • 62 internal links, 11 external

    The homepage links to 62 pages on finstral.com and 11 external pages.

4 checks passed
  • Title: 47 characters

    Your title is a healthy 47 characters: “Windows, entry doors and glass walls - Finstral”.

  • Canonical URL set

    The canonical URL is https://www.finstral.com/en/information/index/1-0.html.

  • robots.txt in place

    robots.txt is in place and points crawlers to your sitemap.

  • XML sitemap found

    Your XML sitemap is reachable at https://www.finstral.com/sitemap.xml.

AI search readiness

100
4 checks passed
  • AI answer engines may read the site

    Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.

  • Organization data: 4 of 6 facts

    Your Organization JSON-LD gives name, url, logo and contact details; sameAs (social profiles) and description would complete it.

  • Text is in the HTML

    Your server sends the page's text in the HTML (485 words), so crawlers that don't run JavaScript still read it.

  • llms.txt published

    The site publishes /llms.txt (25 KiB, 0 links), a plain-text guide to the site for AI tools.

Other pages

2 to fix90
  • 8 pages without a meta description

    /en/company/company/10-0.html, /en/references/references/310-0.html, /en/architect-service/architect-service/12-0.html, /en/partner-programme/partner-programme/60-0.html, /en/contact/dealer-search/31-0.html and /fr/home/1-0.html and 2 others have no meta description, so Google writes the search snippet from whatever text it finds.

  • 9 pages without an H1

    /en/partner-programme/partner-programme/60-0.html, /de/home/1-0.html, /it/home/1-0.html, /fr/home/1-0.html, /es/home/1-0.html and /pt/home/1-0.html and 3 others have no <h1> headline, so visitors and search engines get no clear main topic.

  • 1 page slow to respond

    /pt/home/1-0.html took over 3 s to send its HTML from our server.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 40 found) and read each the way a search engine does.

5 checks passed
  • Linked pages load

    All 15 pages we checked loaded without an error.

  • Canonical URLs point to themselves

    No page we checked hands its ranking to a different URL.

  • Titles are unique

    Every page we checked has its own title.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 15 pages that loaded have a <title>.

Best practices

2 to fixGoogle 9687
  • 21 small tap targets

    21 of 40 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

  • 3 JavaScript errors while loading

    3 errors were logged to the browser console while the page loaded, for example “Error: <path> attribute d: Expected path command, "…,0,0,0,47.2,109Z6Z".”.

1 checks passed
  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

4 to fix50
  • No call to action on the first screen

    On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

  • No calls to action

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

  • No social proof

    No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

  • Local business without LocalBusiness data

    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 opening hours

    The homepage shows no opening hours. If customers visit or call, show when.

  • No form on the homepage

    There is no form on the homepage, so every lead has to click through to another page first.

  • No map or directions link

    There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

  • No risk reducer

    No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

  • About 690 words of copy

    The homepage carries about 690 words of visible text.

3 checks passed
  • Analytics in place

    Analytics detected: Google Tag Manager.

  • Direct contact links

    Visitors can reach you directly: 2 phone links and 0 email links.

  • Phone number on the homepage

    Your phone number is on the homepage as a tap-to-call link.

Privacy and tracking

  • 1 tracker load before any consent

    1

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

  • 11 cookies set on arrival

    11

    Opening the homepage sets 11 cookies (measured from a US location before any click).

  • 5 other companies contacted

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

1 checks passed
  • Consent tool: Cookiebot

    A consent management tool (Cookiebot) loads with the page.
