Speed

4 to fix86

  • Mobile performance score: 86

    86/100

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

  • Render-blocking requests

    850 ms

    3 files block the first paint until they finish downloading. Deferring or inlining them could save about 850 ms.

  • Reduce unused CSS

    300 ms · 61 KiB

    About 61 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.

  • 1,705 HTML elements

    The page has 1,705 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • Improve image delivery

    13 KiB

    1 image could be 13 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • 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.

2 checks passed

  • Main-thread work: 0.4 s

    A phone's processor spends 0.4 s on main-thread work while loading, 83 ms of it running JavaScript. That is comfortably low.

  • Server response: 132 ms

    132 ms

    Your server sent the HTML in 132 ms, well inside Google's 600 ms guideline.

Core Web Vitals

2 to fix100

  • Largest Contentful Paint: 4.1 s

    4.1 s

    Your largest element takes 4.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “NTP - Werken aan een duurzame leefomgeving”.

  • Time to Interactive: 4.1 s

    4.1 s

    The page becomes fully interactive after 4.1 s. Good is under 3.8 s.

  • Tap response (INP) held steady for real visitors

    -3%

    Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 135 ms to 128 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest content (LCP) held steady for real visitors

    +8%

    Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 0.8 s to 0.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

9 checks passed

    1.4 s

    Real visitors wait 1.4 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Real-user INP: 129 ms

  • Real-user CLS: 0.00

    0.00

  • Speed Index: 2.6 s

    2.6 s

    Visually, the page fills in at 2.6 s (Speed Index), inside the 3.4 s “good” threshold.

  • Cumulative Layout Shift: 0.001

    0.001

    The layout barely moves while loading (CLS 0.001, good is under 0.1).

  • Total Blocking Time: 0 ms

    0 ms

    Scripts block the page for only 0 ms while loading. Good is under 200 ms.

Images and page weight

100

  • 1 image in older formats

    1 image (32 KiB) is 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.

  • About 0.3 g of CO₂ per visit

    0.33 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.33 g of CO₂e: 40.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 checks passed

  • Page weight: 1.2 MB in 19 requests

    1.2 MB

    Your homepage downloads 1.2 MB in 19 requests on a phone: fonts 955 KiB (8), stylesheets 93 KiB (3) and scripts 64 KiB (6). That is a lean page.

  • Images load when needed

    Images below the first screen wait until the visitor scrolls to them.

  • Images are sized for phones

    No image is downloaded at more than three times the size it is drawn on a phone.

Accessibility

3 to fixGoogle 9195

  • 1 button without a name

    1 button has no accessible name, so screen readers announce just “button”.

  • 16 text elements with low contrast

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

  • All page content should be contained by landmarks (16 elements)

    All page content should be contained by landmarks: 16 elements on the page fail this check, rated moderate by axe-core.

2 checks passed

  • Every image has alt text

    All 33 images in the HTML carry an alt attribute.

  • 46 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 49 WCAG 2.2 A/AA and best-practice rules on the phone render: 46 passed and 3 failed. 3 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

Google 100100

  • 225 internal links, 11 external

    The homepage links to 225 pages on ntp.nl and 11 external pages.

8 checks passed

  • Meta description: 149 characters

    Your meta description is 149 characters: “NTP is een regionale aannemer en actief op het gebied van wegen, bodem, water, energie en advies ✔️ Samen werken aan to…”.

  • One H1 headline

    Your main headline reads: “Bouwen aan een toekomstbestendige leefomgeving”.

  • Title: 62 characters

    Your title is a healthy 62 characters: “NTP is dé aannemer voor wegen, bodem, water, energie en advies”.

  • Canonical URL set

    The canonical URL is https://ntp.nl/.

  • Structured data in place

    Structured data found: BreadcrumbList, ImageObject, Organization, WebPage and WebSite.

  • Open Graph tags complete

    Open Graph tags are complete, so shared links show a title, description and image.

  • 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://ntp.nl/sitemap_index.xml.

AI search readiness

100

  • No llms.txt

    There is no https://ntp.nl/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.

3 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 sameAs (social profiles); description and contact details would complete it.

  • Text is in the HTML

    Your server sends the page's text in the HTML (1,069 words), so crawlers that don't run JavaScript still read it.

Other pages

1 to fix95

  • 5 pages without a meta description

    https://ntp.nl/disciplines, https://ntp.nl/wegen, https://ntp.nl/bodem, https://ntp.nl/bodem/grondbank and https://ntp.nl/bodem/ijzerschermen have no meta description, so Google writes the search snippet from whatever text it finds.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 95 found) and read each the way a search engine does.

6 checks passed

  • Linked pages load

  • Every page has an H1

    Each page we checked has a main headline.

  • 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>.

  • Mobile viewport set

Content and conversion

3 to fix69

  • 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 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 map 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 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 386 words of copy

    The homepage carries about 386 words of visible text.

5 checks passed

  • 18 calls to action

    The homepage has 18 calls to action, for example “Neem contact op” and “Contact”.

  • 2 short forms

    2 short forms (6 fields at most) are right on the homepage, asking for an email.

  • Analytics in place

    Analytics detected: Google Tag Manager.

  • Direct contact links

    Visitors can reach you directly: 10 phone links and 5 email links.

  • Phone number on the homepage

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

Privacy and tracking

  • 1 cookie set on arrival

    1

    Opening the homepage sets 1 cookie (measured from a US location before any click).

  • No consent tool detected

    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.

1 checks passed

  • No known trackers before consent

    No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).

Security, domain, email and software versions

The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at ntp.nl, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
