speediance.nl website review

Your mobile performance score is 70. Pages that score under 90 lose visitors before the first paint.

17 files block the first paint until they finish downloading. Deferring or inlining them could save about 950 ms.

8 third-party services load with your homepage (omnisnippet1.com, Shopify and Clarity and others), adding 1.4 MB and 794 ms of main-thread time.

omnisnippet1.com costs a phone 455 ms of main-thread work and 119 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.

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.

4 images could be 88 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

Shopify costs a phone 145 ms of main-thread work and 1.2 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.

The page has 1,735 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 169 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

10 files are served with short cache lifetimes, so returning visitors download them again (135 KiB).

About 32 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

8 long tasks block the main thread while loading, the longest for 100 ms. During a long task the page ignores taps.

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.

Your largest element takes 9.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Sir Mark Cavendish training with Speediance”.

The page becomes fully interactive after 14.7 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 113 ms to 234 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Visually, the page fills in at 5.1 s (Speed Index). Good is under 3.4 s.

us.webp weighs 4.5 MB. On a phone connection a single image that size takes seconds.

1 image is downloaded at several times the size a phone draws it, for example us.webp at 3,251 px wide, shown at 390 px. Resized copies would save about 3.9 MB.

Your homepage downloads 4.4 MB in 277 requests on a phone: other files 2.2 MB (110), scripts 753 KiB (97) and fonts 507 KiB (3). Under 2 MB keeps phones on slow connections fast.

5 images (5.0 MB) 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.

3_6.webp 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 1.24 g of CO₂e: 149.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Images must have alternative text: 1 element on the page fails this check, rated critical by axe-core.

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

Form elements should have a visible label: 1 element on the page fails this check, rated serious by axe-core.

Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

Summary elements must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 10 elements on the page fail this check, rated moderate by axe-core.

Heading levels should only increase by one: 1 element on the page fails this check, rated moderate by axe-core.

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

ARIA role should be appropriate for the element: 4 elements on the page fail this check, rated minor by axe-core.

There are 2 <h1> headlines (“” and “Your entire gym.One smart system.”). One clear main headline is easier for people and search engines.

The homepage links to 111 pages on speediance.nl and 18 external pages.

https://speediance.nl/pages/workouts has no meta description, so Google writes the search snippet from whatever text it finds.
