About 841 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.0 s faster on a phone.

14 images could be 1.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.4 s faster on a phone.

Your mobile performance score is 45. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

The page has 3,152 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

7 third-party services load with your homepage (Google Tag Manager, Kameleoon and seamly-app.com and others), adding 7.8 MB and 692 ms of main-thread time.

9 files are served with short cache lifetimes, so returning visitors download them again (212 KiB).

Vimeo costs a phone 0 ms of main-thread work and 7.0 MB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 550 ms.

Google Tag Manager costs a phone 414 ms of main-thread work and 408 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

About 135 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.

A phone's processor spends 3.6 s on main-thread work while loading, 2.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

14 long tasks block the main thread while loading, the longest for 313 ms. During a long task the page ignores taps.

Polyfills for old browsers add 40 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

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

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.

Your homepage downloads 12.3 MB in 113 requests on a phone: media 7.3 MB (1), images 2.0 MB (31) and scripts 1.8 MB (41). Under 2 MB keeps phones on slow connections fast.

image is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 3.47 g of CO₂e: 416.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 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: 3 elements on the page fail this check, rated moderate by axe-core.

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

Your title is only 27 characters: “World of Wonders - Efteling”. Between 30 and 65 characters leaves room to say what you do and for whom.

Your meta description is 201 characters; Google truncates after about 160, so the end of your pitch is cut.

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

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

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

The homepage links to 100 pages on efteling.com and 10 external pages.

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.

/en/park/map has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 60 found) and read each the way a search engine does.

8 of 25 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

Large scripts ship without source maps.

1 link from your homepage to your own site is broken, for example https://www.efteling.com/en/park/annual-pass (500).

1 link to other sites is dead, for example https://m.tiktok.com/h5/share/usr/18937586.html (404).

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

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

Opening https://efteling.com goes through 3 redirects before the homepage loads.

1 link go through two or more redirects, for example https://www.efteling.com/en/account.

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

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

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

efteling.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

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

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.

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 767 words of visible text.

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.

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.

Opening the homepage sets 10 cookies (measured from a US location before any click).

Loading the homepage contacts 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
