msd.nl website review

14 files block the first paint until they finish downloading. Deferring or inlining them could save about 800 ms.

11 files are served with short cache lifetimes, so returning visitors download them again (749 KiB).

3 third-party services load with your homepage (Google Tag Manager, Optanon and ghh.digital), adding 550 KiB and 509 ms of main-thread time.

Google Tag Manager costs a phone 331 ms of main-thread work and 358 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 231 KiB of JavaScript is downloaded but never used on this page.

4 images could be 214 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

6 long tasks block the main thread while loading, the longest for 148 ms. During a long task the page ignores taps.

Polyfills for old browsers add 35 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.

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.

Real visitors wait 942 ms for your server to start answering (75th percentile). Good is under 800 ms.

The page becomes fully interactive after 7.0 s. Good is under 3.8 s.

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

Scripts block taps and scrolling for 265 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 3.6 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.3 s to 1.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

1 image is downloaded at several times the size a phone draws it, for example Digitale-bijsluiter_1213_liggend-02.png at 375 px wide, shown at 72 px. Resized copies would save about 193 KiB.

2 images (436 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.40 g of CO₂e: 48.0 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”.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

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

Elements with visible text labels do not have matching accessible names. (2 elements).

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is only 14 characters: “MSD | Homepage”. Between 30 and 65 characters leaves room to say what you do and for whom.

The homepage links to 47 pages on msd.nl and 13 external pages.

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.

There is no https://msd.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.

https://msd.nl/home and / all use the title “MSD | Homepage”. Search engines can't tell which page to show for a search, so each competes with the others.

https://msd.nl/duurzaamheid, https://msd.nl/ons-bedrijf/geschiedenis, https://msd.nl/ons-bedrijf/onze-maatschappelijke-verantwoordelijkheid, https://msd.nl/ons-bedrijf/cultuur-waarden, https://msd.nl/verhalen and https://msd.nl/onderzoek/onze-aandachtsgebieden and 6 others have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /, whose canonical is https://msd.nl/home. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/, https://msd.nl/onderzoek/geneesmiddelen-msd, https://msd.nl/zorgpartners and https://msd.nl/media/pers-berichten have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 29 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

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

Social proof on the homepage: 1 customer or partner logo. Pairing it with named testimonials or customer logos makes it far more convincing.

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 1,374 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 1 cookie (measured from a US location before any click).

Loading the homepage contacts 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
