Speed

8 to fix54
  • Mobile performance score: 54

    54/100

    Your mobile performance score is 54. Pages that score under 90 lose visitors before the first paint.

  • Reduce unused JavaScript

    600 ms · 374 KiB

    About 374 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.

  • Font display

    650 ms

    Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 650 ms).

  • Use efficient cache lifetimes

    599 KiB

    6 files are served with short cache lifetimes, so returning visitors download them again (599 KiB).

  • 12 long tasks on the main thread

    12 long tasks block the main thread while loading, the longest for 454 ms. During a long task the page ignores taps.

  • Render-blocking requests

    450 ms

    1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 450 ms.

  • Reduce unused CSS

    300 ms · 100 KiB

    About 100 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.

  • Main-thread work: 3.9 s

    A phone's processor spends 3.9 s on main-thread work while loading, 2.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • 7 third-party services on the page

    7 third-party services load with your homepage (cookiebot.eu, Mopinion and XiTi and others), adding 285 KiB and 326 ms of main-thread time.

  • Improve image delivery

    34 KiB

    2 images could be 34 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • Legacy JavaScript

    12 KiB

    Polyfills for old browsers add 12 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.

  • Minify CSS

    3 KiB

    3 KiB could be saved by minifying CSS.

1 checks passed
  • Server response: 4 ms

    4 ms

    Your server sent the HTML in 4 ms, well inside Google's 600 ms guideline.

Core Web Vitals

4 to fix100
  • Time to Interactive: 14.1 s

    14.1 s

    The page becomes fully interactive after 14.1 s. Good is under 3.8 s.

  • Total Blocking Time: 1.7 s

    1.7 s

    Scripts block taps and scrolling for 1.7 s in total while the page loads. Good is under 200 ms.

  • Largest Contentful Paint: 4.2 s

    4.2 s

    Your largest element takes 4.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “homepage header 7”.

  • Speed Index: 6.0 s

    6.0 s

    Visually, the page fills in at 6.0 s (Speed Index). Good is under 3.4 s.

  • Tap response (INP) held steady for real visitors

    +3%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 114 ms to 117 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest content (LCP) held steady for real visitors

    -1%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.7 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

8 checks passed

    Real Chrome users on phones pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)).

  • Real-user LCP: 1.1 s

  • Real-user INP: 106 ms

    106 ms

  • Real-user FCP: 1.0 s

    1.0 s

    Real visitors see the first content after 1.0 s (75th percentile). Good is under 1.8 s.

  • Real-user TTFB: 551 ms

    551 ms

  • First Contentful Paint: 1.2 s

    1.2 s

    The first text or image appears after 1.2 s, inside the 1.8 s “good” threshold.

  • Cumulative Layout Shift: 0

    0

    The layout barely moves while loading (CLS 0, good is under 0.1).

Images and page weight

100
  • About 0.5 g of CO₂ per visit

    0.47 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.47 g of CO₂e: 56.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 checks passed
  • Page weight: 1.6 MB in 45 requests

    1.6 MB

    Your homepage downloads 1.6 MB in 45 requests on a phone: scripts 964 KiB (11), fonts 393 KiB (7) and images 191 KiB (13). That is a lean page.

  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • 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

4 to fixGoogle 9295
  • ARIA dialog and alertdialog nodes should have an accessible name (1 element)

    ARIA dialog and alertdialog nodes should have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

  • All page content should be contained by landmarks (4 elements)

    All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.

  • Landmarks should have a unique role or role/label/title (i.e. accessible name) combination (1 element)

    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.

  • 1 link without text

    1 visible link has no text or label, so screen readers cannot say where it goes.

  • Headings skip levels

    Headings skip levels (h1 → h4), which makes the page harder to scan with a screen reader.

2 checks passed
  • Every image has alt text

    All 23 images in the HTML carry an alt attribute.

  • 48 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 53 WCAG 2.2 A/AA and best-practice rules on the phone render: 48 passed and 5 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

3 to fixGoogle 9290
  • Structured data has 2 problems

    Structured data found (Organization) but with 2 problems, for example “Organization: logo is not an absolute URL ("/_resources/themes/default/images/logo.png?m=1793704095…”.

  • No XML sitemap

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

  • 1 link crawlers can't follow

    1 link has no real href, so search engines can't follow it.

  • 110 internal links, 9 external

    The homepage links to 110 pages on feenstra.com and 9 external pages.

6 checks passed
  • Meta description: 155 characters

    Your meta description is 155 characters: “Dé landelijke expert in installatie en onderhoud van verwarming, koeling, ventilatie, zonne-energie & opslag. Cv-ketel …”.

  • One H1 headline

    Your main headline reads: “Thuis, daar draait het om.”.

  • Title: 36 characters

    Your title is a healthy 36 characters: “Feenstra. Thuis, daar draait het om.”.

  • Canonical URL set

    The canonical URL is https://www.feenstra.com/.

  • 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.

AI search readiness

1 to fix88
  • Organization data is thin (3 of 6 facts)

    Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

  • No llms.txt

    There is no /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.

2 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.

  • Text is in the HTML

    Your server sends the page's text in the HTML (628 words), so crawlers that don't run JavaScript still read it.

Other pages

100
  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 47 found) and read each the way a search engine does.

7 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.

  • Every page has a meta description

    All 15 pages that loaded have a meta description.

  • Titles are unique

    Every page we checked has its own title.

  • 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>.

Best practices

Google 100100
  • Missing source maps

    Large scripts ship without source maps.

3 checks passed
  • No console errors

    No JavaScript errors were logged while the page loaded on a phone.

  • Tap targets are thumb-sized

    27 of 30 tappable elements near the top are at least 24 px.

  • Mobile viewport set

    The page declares a mobile viewport.

Security and trust

1 to fix94
  • No HSTS header

    No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

  • No X-Content-Type-Options

    X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

  • No Referrer-Policy

    No Referrer-Policy header, so full URLs can leak to the sites you link to.

  • No Permissions-Policy

    No Permissions-Policy header to switch off camera, microphone and location for embedded content.

  • No security.txt

    There is no /.well-known/security.txt telling researchers how to report a security problem to you.

7 checks passed
  • Served over HTTPS

    The homepage is served over HTTPS (feenstra.com).

  • Valid certificate (80 days left)

    The certificate from Sectigo Limited · Sectigo Public Server Authentication CA DV R36 verifies for feenstra.com and is valid for another 80 days.

  • Protected from clickjacking

    X-Frame-Options or a frame-ancestors policy stops other sites framing yours.

  • Content-Security-Policy set

    A Content-Security-Policy is set, the main browser-side defence against injected scripts.

  • http:// redirects to https

    http://feenstra.com redirects to the secure version.

  • HTTP/2 and HTTP/3

    The server speaks HTTP/2 and advertises HTTP/3, so browsers load many files over one connection.

  • All 46 links work

    All 46 links checked from your homepage (40 internal, 6 external) answered without errors.

Domain and trust

4 checks passed
  • Domain is 28 years old

    28 years

    feenstra.com was registered in Aug 1998 through Ascio Technologies, Inc. Danmark - Filial af Ascio technologies, Inc. USA. An established domain carries more trust with email providers and search engines.

  • Certificate issuers are restricted

    CAA records allow only digicert.com, letsencrypt.org, pki.goog and sectigo.com to issue certificates for feenstra.com, so a mis-issued certificate from anyone else is refused.

  • DNSSEC is on

    feenstra.com's DNS answers are signed (DNSSEC), so they can't be forged on the way to visitors.

  • Registered until Aug 2027

    feenstra.com is registered until Aug 2027.

Content and conversion

5 to fix69
  • 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 phone number on the homepage

    A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

  • Thin social proof

    Social proof on the homepage: a star rating. Pairing it with named testimonials or customer logos makes it far more convincing.

  • No analytics detected

    No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

  • No direct contact details

    No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

  • No opening hours

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

  • 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 512 words of copy

    The homepage carries about 512 words of visible text.

3 checks passed
  • Clear next step on the first screen

    On a phone, the first screen shows a clear next step: “Contact”.

  • 4 calls to action

    The homepage has 4 calls to action, for example “Contact” and “E-book Hoe zit het met de warmtepomp”.

  • 2 short forms

    2 short forms (1 field at most) are right on the homepage.

Email authentication

2 to fix60
  • DMARC is monitor-only (p=none)

    DMARC is set to p=none, so mail pretending to be feenstra.com is still delivered. Reports are on, so moving to quarantine is the next step.

  • SPF does not block other senders (no all)

    Your SPF record doesn't end in -all or ~all, so it doesn't stop other servers sending as you: “v=spf1 redirect=4412yljs._spf._d.mim.ec”.

  • Email authentication score: 60/100

    Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

1 checks passed
  • DKIM signing found

    A DKIM key is published (selector “selector1”, “s1” and “s2”), so receivers can verify mail really came from you.

Privacy and tracking

  • 2 trackers load before any consent

    2

    Before a visitor clicks anything, the page loads Google Ads and Google Analytics (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.

  • 18 cookies set on arrival

    18

    Opening the homepage sets 18 cookies (measured from a US location before any click).

  • 12 other companies contacted

    Loading the homepage contacts 12 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.
