acon24.com website review

A phone's processor spends 4.0 s on main-thread work while loading, 2.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (ZenDesk, Yotpo and Shopify and others), adding 1.8 MB and 938 ms of main-thread time.

Your mobile performance score is 59. Pages that score under 90 lose visitors before the first paint.

About 477 KiB of JavaScript is downloaded but never used on this page.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

ZenDesk costs a phone 285 ms of main-thread work and 435 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.

8 images could be 306 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Shopify costs a phone 158 ms of main-thread work and 886 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.

The page has 2,421 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

13 files are served with short cache lifetimes, so returning visitors download them again (240 KiB).

12 long tasks block the main thread while loading, the longest for 192 ms. During a long task the page ignores taps.

Polyfills for old browsers add 18 KiB JavaScript that modern phones do not need.

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

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

3 KiB could be saved by minifying JavaScript.

Your largest element takes 8.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Three children in Halloween costumes sitting together on an…”.

The page becomes fully interactive after 19.2 s. Good is under 3.8 s.

Visually, the page fills in at 6.4 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 380 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 99 ms to 106 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.8 MB in 249 requests on a phone: scripts 1.4 MB (98), images 976 KiB (25) and other files 678 KiB (98). Under 2 MB keeps phones on slow connections fast.

3 images (684 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.

1 image further down the page (172 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.07 g of CO₂e: 128.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

10 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: 1 element on the page fails this check, rated moderate by axe-core.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

Your title is 70 characters, so Google will cut it off around 60: “ACON EU – Trampoline Shop online - trampolines and airtracks – Acon EU”.

Your meta description is 180 characters; Google truncates after about 160, so the end of your pitch is cut.

Structured data found (BreadcrumbList, Organization and WebSite) but with 2 problems, for example “Organization: missing name”.

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

The homepage links to 136 pages on acon24.com and 31 external pages.

/customer_authentication/redirect has no <title>, so Google invents the link text in results.

/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/customer_authentication/redirect has no meta description, so Google writes the search snippet from whatever text it finds.

/customer_authentication/redirect has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 58 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://cdn-widget-assets.yotpo.com/ReviewsStarRatingsWidget/AU8hUWl7TljQCND6vxkXMrl5EnEFc…”.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

1 link go through two or more redirects, for example https://www.acon24.com/customer_authentication/redirect?locale=en-GB&region_country=FI.

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.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

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

acon24.com is registered until Jan 2027. Make sure auto-renew is on and the card on file is current.

acon24.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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 1,261 words of visible text.

DMARC is set to p=none, so mail pretending to be acon24.com is still delivered. Reports are on, so moving to quarantine is the next step.

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 Klaviyo and Microsoft Clarity (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 8 cookies (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 26 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
