Optimize images and videos:
Large image and video files can contribute to slow LCP times. Compress and resize images appropriately, and use lazy loading techniques to defer the loading of off-screen images and videos until they are needed.
Use a content delivery network (CDN):
CDNs distribute your website’s content across multiple servers worldwide, reducing the distance between the user and the server. This helps deliver content faster and improve LCP.
2. First Input Delay (FID)
First Input Delay (FID) measures the time it takes for a web page to respond to the first user interaction, such as clicking a button or selecting a menu item. It quantifies the interactivity of a page and reflects how quickly users can start engaging with it.
FID is crucial because it indicates whether a page is responsive or if there are delays that frustrate users. It is measured in milliseconds, and a good FID score should be 100 milliseconds or less.
Improving FID
To improve FID, consider the following strategies:
Optimize JavaScript execution:
JavaScript can be a common cause of high FID. Minimize and optimize your JavaScript code by eliminating unnecessary scripts, reducing dependencies, and using code splitting techniques to load only what is necessary for the initial user interaction.
Defer non-critical JavaScript:
Delay loading non-essential JavaScript until after the page has finished rendering and become interactive. This allows users to start interacting with the page sooner, improving FID.
Optimize third-party scripts:
Third-party scripts, such as analytics or advertising scripts, can introduce delays. Evaluate the necessity of each script and consider alternatives or asynchronous loading techniques to prevent them from blocking user interactions.
Prioritize main thread tasks:
Ensure that the main thread, responsible for handling user interactions, is not overwhelmed with heavy tasks. Optimize long tasks, minimize layout shifts, and prioritize critical rendering path elements to improve FID.
3. Cumulative Layout Shift (CLS)
Cumulative Layout Shift (CLS) measures the visual stability of a web page by quantifying how much the content shifts during the loading process. It calculates the sum of all individual layout shift scores, where a layout shift occurs when visible elements change their position unexpectedly.
CLS is crucial for providing a smooth and frustration-free user experience. A good CLS score should be 0.1 or less.
Improving CLS
To improve CLS, consider implementing the following strategies:
Size and position elements:
Ensure that all elements on the page have explicit dimensions and positions. This prevents them from shifting unexpectedly and causing layout shifts.
Preload and preconnect resources:
Use the `preload` and `preconnect` HTML attributes to give the browser a hint about resources that will be needed in the future. This allows the browser to load and position them correctly, reducing layout shifts.
Avoid inserting content above existing elements:
Avoid dynamically inserting content above existing elements, as this can cause unexpected layout shifts. Reserve space for dynamic content or use placeholders to maintain visual stability.
Lazy load images and videos:
Use lazy loading techniques to defer the loading of images and videos until they are about to enter the viewport. This prevents them from pushing down existing content and causing layout shifts.
By focusing on these Core Web Vitals metrics and implementing the suggested strategies, website owners can enhance the user experience, improve performance, and ultimately drive better engagement and conversions.
