Website laadsnelheid has a major impact on both SEO and UX. Core Web Vitals are key web-prestaties indicators proposed by Google, and their importance is only increasing in 2024 and beyond. A slow site frustrates users, lowers rangschikkings, and increases afhaken.
This article covers practical techniques from the basics of Core Web Vitals to explanations of the major metrics LCP, FID, and CLS, along with how to meten them using tools such as PageSpeed Insights and Search Console and how to verbeteren them in concrete ways.
Start optimizing Core Web Vitals now to verbeteren SEO and UX and turn your website into a stronger success.
Wat zijn Core Web Vitals? Een gedetailleerde blik op hun effect op SEO en UX
Waarom Core Web Vitals belangrijk zijn voor SEO in 2024 en moderne UX
Core Web Vitals are website prestaties indicators proposed by Google. They meten three aspects of how users experience a web pagina: laadsnelheid, interactivity, and visual stability. In other words, they evaluate whether a site is actually delivering a good gebruikerservaring.
W SEO w 2024 roku Core Web Vitals stały się jeszcze ważniejsze. Google coraz mocniej stawia na wyszukiwanie skoncentrowane na użytkowniku i zwykle wyżej ocenia strony, które zapewniają wygodne korzystanie z sieci. W praktyce optymalizacja Core Web Vitals jest teraz niezbędnym elementem pracy SEO.
We strongly recommend that site owners verbeteren Core Web Vitals so they can rank better in zoekresultaten and deliver a better overall gebruikerservaring.Core Web Vitals are one of the factors that Google’s core rangschikking systems consider, along with other pagina-experience signals, when determining rangschikkings.
Core Web Vitals en Google Search-resultaten
A strong UX verbeterens user satisfaction and directly supports business success through better conversion rates, more repeat visitors, and a stronger brand image.
Begrijp de drie belangrijkste metrieken: LCP, FID en CLS
Core Web Vitals składają się z trzech poniższych wskaźników. Przyjrzyjmy się konkretnie, co oznacza każdy z nich.
- LCP (Largest Contentful Paint): the time it takes until the main visual content on the page, such as a large image, video, or text block, is displayed. Because it represents when users can recognize the main content, it is a crucial indicator of loading speed. The target value is 2.5 seconds or less.
- FID (First Input Delay): the time between a user’s first interaction, such as clicking a link or pressing a button, and the browser’s response. It measures how quickly the page becomes responsive to user action. The target value is 100 milliseconds or less.
- CLS (Cumulative Layout Shift): how much unexpected layout movement occurs while the page is being displayed. For example, if an image loads late and suddenly pushes text downward, that is layout shift. A high CLS can cause accidental clicks and damages UX. The target value is 0.1 or less.
De nauwe relatie tussen Core Web Vitals en gebruikerservaring
Core Web Vitals are closely tied to gebruikerservaring.
For example, if product images take too long to appear on an ecommerce site, or buttons respond slowly when clicked, users may become frustrated and leave. On the other hand, when paginas load quickly and interactions feel smooth, users can shop comfortably and are more likely to make a purchase.
Wat gebeurt er als Core Web Vitals slecht zijn? Rangschikkingsrisico en meer afhakers
Poor Core Web Vitals can hurt Google rangschikkings. In particular, if you want to rank for competitive keywords, optimization is indispensable.
Sites with poor Core Web Vitals also tend to have higher afhaken rates. When paginas are slow or hard to interact with, users feel stress and leave.
A higher afhaken rate can lower conversion rates and damage brand perception. For example, if a site with one million monthly pagina views sees a 10 percent increase in afhaken, the resulting annual loss can easily amount to tens of millions of yen.

Hoe u Core Web Vitals verbetert
Verbeter LCP met afbeeldingsoptimalisatie en door renderblokkerende resources te verwijderen
The main ways to verbeteren LCP are as follows.
- Optimize images: reducing image file sizes shortens load time. Using next-generation formats such as WebP and compressing images to the right size can reduce file size significantly.
- Remove render-blocking resources: if resources such as CSS and JavaScript block page rendering, LCP can worsen. Removing unnecessary resources or applying deferred loading can reduce that blocking effect.
- Use a CDN: by delivering content from servers distributed around the world, a content delivery network can shorten load times.
Verbeter FID met JavaScript-optimalisatie en minder onnodige taken
The main ways to verbeteren FID are as follows.
- Optimize JavaScript: when JavaScript processing takes too long, FID can worsen. Optimizing code and avoiding unnecessary script execution can improve responsiveness.
- Reduce unnecessary tasks: long-running tasks reduce browser responsiveness. Breaking tasks into smaller pieces or using Web Workers for background processing can improve FID.
- Optimize third-party scripts: if external service scripts are hurting FID, review how they load or consider alternatives.
Verbeter CLS met afbeeldingsafmetingen en lettertype-optimalisatie
The main ways to verbeteren CLS are as follows.
- Specify image dimensions: when width and height are set on images, the browser can reserve the right amount of space before loading and prevent layout shift.
- Optimize font loading: if fonts take too long to load, text rendering can be delayed and create layout shift. Using properties such as font-display can improve CLS.
- Reserve space for ads and embedded content: ads and embeds can also trigger layout shift, so define their dimensions appropriately in advance.
Specifieke technieken die u meteen kunt toepassen
Best practices voor afbeeldingsoptimalisatie
Optymalizacja obrazów jest jednym z głównych czynników poprawiających LCP. Oto kilka konkretnych technik.
- Use WebP: WebP is a next-generation image format developed by Google. It usually offers smaller file sizes than JPEG or PNG while maintaining strong visual quality, so use it where browsers support it.
- Use image-compression tools: tools such as TinyPNG and ImageOptim can significantly reduce file size while preserving acceptable quality.
- Use responsive images: by using srcset and sizes, you can deliver images that fit each device’s screen size better.
- Use lazy loading: delaying the loading of images outside the viewport can speed up the initial display. The loading=\"lazy\" attribute makes this easy to implement.
On WordPress, image optimization can often be verbeterend easily by installing a plugin.

Five WordPress plugins that dramatically verbeteren speed and the metens that matter
Gebruik browsercaching effectief
When you use browser caching, resources that have already been loaded can be stored in the browser and reused on subsequent visits. That can verbeteren laadsnelheid significantly.
Aby włączyć buforowanie, trzeba ustawić odpowiednie nagłówki HTTP po stronie serwera. Na przykład nagłówki Cache-Control można wykorzystać do określenia, jak długo zasoby pozostają ważne.
Versnel de levering met een CDN
CDN, czyli Content Delivery Network, to rozproszona sieć serwerów rozmieszczonych na całym świecie. Korzystając z CDN, możesz dostarczać treści z serwerów bliższych użytkownikowi i skracać czas ładowania.
Wpływ ten jest szczególnie duży w przypadku stron odwiedzanych przez wielu użytkowników z zagranicy.

Optimaliseer JavaScript en CSS
Reducing the file size of JavaScript and CSS and optimizing how they load can verbeteren both LCP and FID.
- Minify files: removing unnecessary spaces and comments reduces file size.
- Defer loading: if JavaScript or CSS blocks rendering, delaying those resources can speed up the initial view.
- Split code: dividing large JavaScript files into smaller chunks and loading only what is needed reduces the initial download volume.
Verbeter de serverresponstijd
Server response speed directly affects LCP. The following metens are effective for improving response time.
- Choose a fast server: using high-performance hosting can improve response speed.
- Use server-side caching: caching database queries and API responses can reduce server load and improve response speed.
- Optimize the database: optimizing queries reduces the time needed to retrieve data.
We metend server speed directly to find out which hosting services are actually fast.
Core Web Vitals en mobielvriendelijkheid
Mobile browsing continues to grow every year, which means mobielvriendelijkheid is no longer optional. Core Web Vitals matter on mobile too, and mobile prestaties optimization directly supports both SEO and UX.
Waarom mobile-first indexing mobiele optimalisatie essentieel maakt
Google uses mobile-first indexing, meaning the mobile version of a pagina is treated as a primary factor in determining rangschikkings.
Google nadal zaleca webmasterom tworzenie treści przyjaznych dla urządzeń mobilnych.Google ocenia całą zaindeksowaną dla witryny treść, zarówno wersję desktopową, jak i mobilną, aby określić, jak dobrze wspiera ona urządzenia mobilne.
Wdrożenie indeksowania mobile-first
In other words, poor Core Web Vitals on mobile can negatively affect rangschikkings. It is important to adopt responsive design and provide a fast, comfortable web experience on mobile devices as well.
Lever de beste mobiele ervaring met responsief design
Responsive design to podejście do projektowania stron, które wykorzystuje jeden źródłowy plik HTML, aby obsługiwać wiele rozmiarów ekranów. Dzięki użyciu zapytań medialnych CSS do dostosowywania układu i treści do ekranu możesz zapewnić optymalny wygląd na komputerach, tabletach i smartfonach.
Jeśli możesz obsłużyć oba środowiska jedną witryną, zachowasz adresy kanoniczne, unikniesz złożonych przekierowań i uprościsz współdzielone adresy internetowe.
Responsive web design i moc zapytań medialnych
Responsive design is a basic requirement for mobielvriendelijkheid and also helps verbeteren Core Web Vitals.
Moet u AMP overwegen voor ultrasnelle levering?
AMP, or Accelerated Mobile Pages, is a framework for displaying mobile paginas at high speed.
By using specialized AMP HTML and restricting JavaScript execution, it can dramatically verbeteren pagina-load speed. AMP paginas can also be delivered through Google’s cache servers, allowing even faster display.
Jednak AMP ma ograniczenia funkcjonalne, więc nie nadaje się do każdej witryny.
AMP itself does not directly strengthen SEO rangschikkings.
Whether a site includes valid and displayable AMP paginas does not affect rangschikkings in zoekresultaten at all.The difference is that when a site includes AMP paginas, an AMP icon may be added in zoekresultaten.
