Design Tips & Best Practices
Improve Website Conversions : Optimize Core Web Vitals
When it comes to creating a successful website, you’re probably focused on design – captivating visuals, intuitive navigation, and a user-friendly interface. But there’s another crucial factor that can significantly impact your website’s success: Core Web Vitals.
Core Web Vitals are a set of key metrics that Google uses to measure the user experience of a webpage. These metrics directly impact your website’s search engine rankings and, ultimately, your bottom line.

What are Core Web Vitals?
Core Web Vitals focus on three key aspects of user experience:
- Largest Contentful Paint (LCP): How quickly the largest content element on the page loads.
- First Input Delay (FID): How quickly a website responds to user interactions (e.g., clicking a button).
- Cumulative Layout Shift (CLS): How much the page content visually shifts around during loading.
The Impact of UI Design on Core Web Vitals
You might be surprised to learn that your UI design choices directly influence these critical metrics.
- Slow LCP: Large images, videos, or heavy use of custom fonts can significantly slow down loading times, impacting LCP.
- High FID: Overly complex animations, heavy JavaScript interactions, or slow-loading forms can lead to a high FID, frustrating users.
- High CLS: Unexpected layout shifts caused by images loading after the text, ads appearing suddenly, or elements resizing during loading can negatively impact CLS.
Optimizing Your UI Design for Core Web Vitals
Here’s how to align your design choices with Core Web Vitals best practices:
Prioritize LCP:
- Optimize images: Use modern image formats like WebP and SVG, and implement lazy loading to defer image loading until needed.
- Minimize CSS and JavaScript: Reduce the number of critical CSS and JavaScript files to improve initial page load speed.
- Optimize fonts: Use system fonts whenever possible and choose web fonts carefully to minimize loading times.
Improve FID:
- Prioritize interactivity: Ensure that buttons, forms, and other interactive elements are responsive and don’t cause delays.
- Minimize JavaScript execution time: Use code splitting and lazy loading to defer non-essential JavaScript.
- Optimize for mobile: Ensure your website is fully responsive and performs well on all devices.
Reduce CLS:
- Define image dimensions: Always specify the width and height of images in your HTML or CSS.
- Avoid unexpected layout shifts: Use CSS Grid and Flexbox for better layout control and prevent elements from jumping around.
- Minimize the use of large, above-the-fold ads.
