If you’re involved in SEO and user experience, you’ve probably heard of the term Core Web Vitals. Core Web Vitals is a set of metrics related to web performance and user experience defined by Google. These metrics include:

•  Largest Contentful Paint (LCP)
•  First Input Delay (FID)
•  Cumulative Layout Shift (CLS)

Web user experience is very important for any site. Users expect a site’s pages to load quickly and they can access content without delay. Users of a site have the right to be dissatisfied with unwanted movement of elements and delays in responding to their interactions. That is why Google pays special attention to improving the web user experience and has introduced the concept of Core Web Vitals. The main goal of this text is to familiarize you with the concept of Core Web Vitals and its importance in improving the quality and performance of web pages. By understanding and learning core web vitals and the principles of these criteria and their impact on user experience, you can optimize your site and create a better experience for your users.

By the end of this article with Gelavizh Stay tuned.

What are Core Web Vitals?

As we mentioned at the beginning, core web vitals actually include metrics that measure the user experience of sites. Core web vitals metrics include:

1. Largest Contentful Paint (LCP)

LCP refers to the time it takes for the largest perspective content on a page (such as an image or video) to be fully loaded and displayed. In essence, this metric tells us how long it takes for the most important and visible part of the page to load for users. A lower LCP time indicates a faster loading speed of the site, which improves the user experience.

2. First Input Delay (FID)

FID measures the time it takes for a user to click on the first interactive element (such as a button or link) on a page until the browser responds. This metric tells us how long it takes for a site to respond to user interactions.

3. Cumulative Layout Shift (CLS)

CLS is used to measure the unwanted movement of elements on a page. When a page loads, elements may move around unintentionally, which can disrupt the user experience. CLS tells us how many elements move during the page’s performance and affect it. This metric helps us understand how stable a page is.

Each of these metrics is important for improving the performance and user experience of the web. According to Google research, sites that score well on Core Web Vitals metrics have higher user satisfaction. Each of these metrics can be improved by web optimization professionals. By optimizing your site, you can reduce page load times so that users can access important content faster. By improving FID, you can increase your site’s response time so that users can better interact with your website. By improving CLS, you can also reduce unwanted element movement on your pages.

Core Web Vitals metrics

Detailed description of LCP

As we mentioned, Largest Contentful Paint (LCP) is one of the Core Web Vitals metrics and refers to the time it takes for the largest visible element (content) on a page to fully load and display. The impact of LCP on users is very important because the time it takes for the main content of a page to load is directly related to user experience and satisfaction. Long LCP load times can make users feel unresponsive and dissatisfied, and potentially lead to a decrease in the bounce rate and conversion rate of a website.

To improve LCP, you can use the following strategies and techniques:

1. Optimize images: Use more compressed formats like JPEG with decent quality and image compression tools like MozJPEG or WebP.
2. Lazy load: Optimize your site so that only the content necessary for the initial display is loaded, and other sections that require scrolling are loaded lazily.
3. Optimize CSS and JavaScript: Reducing the size of CSS and JavaScript and removing unnecessary and unused code can improve content loading time.
4. Using fast servers: Using powerful and fast servers will increase the loading speed of the site.
5. Use a CDN: Using a content distribution network (CDN) can distribute your site files virtually around the world, which improves several aspects of site performance, including LCP load times.
6. Server Optimization: Make sure your server is optimized and able to respond quickly to requests.
7. Improve network speed: You can reduce page load time by compressing, reducing the number of requests, and optimizing HTTP headers. You can also use technologies like HTTP/2 and HTTP/3.
8. Visible Sitemap: See if your site design pattern is optimized and reduces overall content display time.
9. Continuous Monitoring and Review: By using site performance monitoring and analysis tools, you can identify problems and conduct continuous reviews to improve page load times.

By using these strategies and techniques, you can improve your LCP score and reduce the time it takes to load your site’s pages.

Detailed explanation of FID

First Input Delay (FID) is a metric that reflects the time it takes for the system to be ready to process a user response. FID is measured by JavaScript. The response time of a page to user interaction is very important. To improve FID, you can use the following strategies and techniques:

1. Optimize Blocking Resources: Check if resources such as CSS or JavaScript files are causing delays in page rendering and responsiveness to user interaction. Optimizing and compressing these resources can help improve FID.
2. Lazy loading: Use lazy loading technique to delay loading of unnecessary resources. For example, large images and complex resource previews can be loaded lazily to improve FID.
3. Use Workers: Using Web Workers to perform behind-the-scenes operations and actions can help speed up user response and improve FID.
4. Code optimization: Improving JavaScript code and removing unnecessary code blocks can reduce page response time and improve FID.
5. Prefetching: Using the Prefetching technique, some resources may be loaded before they are needed. This feature can improve response time to user interaction.

Detailed explanation of CLS

Cumulative Layout Shift (CLS) refers to the amount of movement of elements on a page as content is loaded and displayed. CLS is measured using an estimated equation that takes the sum of the width and height of an element at each shift and divides it by the total number of shifts. Unexpected element shifts can have a significant impact on the user experience. For example, when a user clicks on a link but instead of opening the intended page, an element moves unexpectedly; this is certainly confusing and frustrating for the user.

To improve CLS, you can use the following strategies and techniques:

1. Specify element dimensions: Set required display values ​​for elements so that changes in content do not cause unwanted scrolling. You can reduce CLS by using fixed dimensions or sizing elements based on the content being loaded.
2. Secondary resources: Make sure that elements like images and ads load after the content has fully loaded. This helps with the user experience and reduces unexpected navigation.
3. Large page changes: If you need to make large changes to your site page, it is better to use techniques like Transition and Animation. By applying these changes slowly and gradually, you will reduce CLS.
4. Review and Test: Review and test using various tools can help you identify the various factors that cause CLS and find appropriate solutions to improve them. Tools like Google PageSpeed ​​Insights and Lighthouse can help you in this regard.

By implementing these strategies and improving your content and page design, you can minimize CLS and create a better experience for your users.

Frequently Asked Questions

1. What are Core Web Vitals and why are they important for SEO?

Core Web Vitals are a set of key web performance metrics introduced by Google to assess real-world user experience. These metrics include LCP, FID, and CLS, and focus on page loading speed, responsiveness, and stability. Improving these factors increases user satisfaction, reduces bounce rates, and improves rankings in Google search results.

2. What does the Largest Contentful Paint criterion mean?

LCP shows the time it takes for the largest visible part of a page’s content (such as an image or the main headline) to load for the user. If the LCP time is below 2.5 seconds, it is considered a great user experience. To improve it, you should compress images, use a CDN, and remove unnecessary CSS and JS code.

3. How can the FID or First Input Delay metric be improved?

FID is the time it takes for a site to respond to the first user interaction (such as a click or tap on a page). To reduce FID, you should remove or compress blocking scripts, use Web Workers for heavy processing, and defer loading unnecessary resources. The goal is to keep FID below 100 milliseconds.

4. What is CLS or Cumulative Layout Shift and how is it controlled?

CLS measures the amount of sudden movement of page elements during loading. To reduce it, you should pre-define the dimensions of images and videos, use optimized fonts, and load ads or banners in a way that doesn’t change the layout of the page. A CLS value of less than 0.1 is ideal.

5. What tools are available to measure Core Web Vitals?

Google provides official tools like PageSpeed ​​Insights, Lighthouse, Chrome DevTools, and the Web Vitals Extension. Tools like GTmetrix, Pingdom, and WebPageTest can also be used to more accurately analyze page speed and performance.

6. Do Core Web Vitals have a direct impact on Google rankings?

Yes. Since 2021, Google has introduced Core Web Vitals as a Ranking Factor. Sites that perform better on these metrics have a better chance of ranking higher in search results compared to slower, unstable competitors.

7. What is the best way to simultaneously improve LCP, FID, and CLS?

To optimize Core Web Vitals overall, you should use a combination of the following methods:

• Image Compression and Lazy Loading

• Remove or postpone loading of unnecessary scripts
• Use of fast servers and CDN
• Defining fixed dimensions for elements
• Optimize CSS and JavaScript codes

Implementing these items will increase speed, stability, and improve user interaction with the site.
