Render-blocking requests
1.6 s8 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.6 s.
Use efficient cache lifetimes
800 ms · 12.6 MB22 files are served with short cache lifetimes, so returning visitors download them again (12.6 MB).
Mobile performance score: 77
77/100Your mobile performance score is 77. Pages that score under 90 lose visitors before the first paint.
Improve image delivery
565 KiB1 image could be 565 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.
Document request latency
138 KiBThe HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.
Font display
100 msWeb fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).
1 long task on the main thread
1 long task block the main thread while loading, the longest for 74 ms. During a long task the page ignores taps.
Reduce unused CSS
57 KiBAbout 57 KiB of CSS is downloaded but never applied on this page.
Reduce unused JavaScript
36 KiBAbout 36 KiB of JavaScript is downloaded but never used on this page.
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.
1 third-party service on the page
1 third-party service load with your homepage (Google Fonts), adding 37 KiB and 0 ms of main-thread time.
Minify CSS
2 KiB2 KiB could be saved by minifying CSS.

Main-thread work: 0.7 s
A phone's processor spends 0.7 s on main-thread work while loading, 134 ms of it running JavaScript. That is comfortably low.
Server response: 339 ms
339 msYour server sent the HTML in 339 ms, well inside Google's 600 ms guideline.
Core Web Vitals
Speed Index: 12.8 s
12.8 sVisually, the page fills in at 12.8 s (Speed Index). Good is under 3.4 s.
Time to Interactive: 6.1 s
6.1 sThe page becomes fully interactive after 6.1 s. Good is under 3.8 s.
Largest Contentful Paint: 3.5 s
3.5 sYour largest element takes 3.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image. Most of its time is resource load delay (6.4 s).
First Contentful Paint: 2.6 s
2.6 sThe first text or image appears after 2.6 s on a phone. Good is under 1.8 s.
Not enough real-visitor data yet
Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.
2 checks passed
Cumulative Layout Shift: 0.051
0.051The layout barely moves while loading (CLS 0.051, good is under 0.1).
Total Blocking Time: 12 ms
12 msScripts block the page for only 12 ms while loading. Good is under 200 ms.
Images and page weight
Page weight: 12.8 MB in 25 requests
12.8 MBYour homepage downloads 12.8 MB in 25 requests on a phone: media 11.7 MB (1), images 617 KiB (4) and scripts 220 KiB (10). Under 2 MB keeps phones on slow connections fast.
About 3.6 g of CO₂ per visit
3.63 gBy the Sustainable Web Design model, a visit to your homepage emits about 3.63 g of CO₂e: 435.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
3 checks passed
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
7 text elements with low contrast
7 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
7 tap targets too small
7 tap targets are too small or too close together to hit reliably with a finger.
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.
21 links without text
21 visible links have no text or label, so screen readers cannot say where they go.
Headings skip levels
Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.
2 checks passed
Every image has alt text
All 17 images in the HTML carry an alt attribute.
44 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: 44 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
No meta description
No meta description, so Google writes its own snippet from whatever text it finds.
Title is long (88 characters)
Your title is 88 characters, so Google will cut it off around 60: “Xelero — Growth. Value. Exit. – Strategische executie voor ondernemers en investeerders.”.
No structured data
No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.
No social preview image
No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.
No X (Twitter) card tag
No twitter:card tag. X falls back to Open Graph, which is incomplete here.
84 internal links, 0 external
The homepage links to 84 pages on xelero.nl and 0 external pages.
4 checks passed
One H1 headline
Your main headline reads: “Versnellen. Verwaarden. Verkopen.”.
Canonical URL set

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://www.xelero.nl/wp-sitemap.xml.
AI search readiness
No Organization structured data
There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.
No llms.txt
There is no https://www.xelero.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.
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 (880 words), so crawlers that don't run JavaScript still read it.
Other pages
12 pages without a meta description
https://www.xelero.nl/wie, https://www.xelero.nl/wat, https://www.xelero.nl/resultaat, https://www.xelero.nl/commitment, https://www.xelero.nl/werkwijze and https://www.xelero.nl/leer-van-de-benchmark and 6 others have no meta description, so Google writes the search snippet from whatever text it finds.

Content and conversion
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.
Thin social proof
Social proof on the homepage: 9 testimonial or review blocks. 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 form on the homepage
There is no form on the homepage, so every lead has to click through to another page first.
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.

2 checks passed

Privacy and tracking
1 cookie set on arrival
1Opening the homepage sets 1 cookie (measured from a US location before any click).

1 checks passed
