What Are Core Web Vitals?

Core Web Vitals consist of three specific metrics that focus on different aspects of user experience.

Largest Contentful Paint (LCP)

LCP measures loading performance, specifically how long it takes for the largest visible element on the page to load. This metric is crucial because it reflects the perceived load speed of a webpage. For an optimal user experience, LCP should occur within 2.5 seconds after a user initiates loading a page. If it takes longer than that, users may perceive the site as slow and may choose to leave.

Interaction to Next Paint (INP)

INP assesses interactivity by measuring the time between a user’s first interaction (like a click) and the next visual change on the screen. A low INP indicates that the page responds quickly to user actions, which is vital for maintaining user engagement. Ideally, the INP should be less than 200 milliseconds.

Cumulative Layout Shift (CLS)

CLS evaluates visual stability by measuring how much the layout shifts as the page loads. Unexpected shifts can lead to a frustrating user experience, especially if a user is trying to click on a link or button that suddenly moves. A good CLS score is 0.1 or less.

Together, these metrics provide a snapshot of the user experience on a website, and optimizing them can lead to improved engagement, lower bounce rates, and enhanced search rankings.

Tools for Auditing Core Web Vitals

Before diving into the audit process, we need to familiarize ourselves with the tools at our disposal to measure Core Web Vitals effectively.

Google PageSpeed Insights

This tool allows users to analyze the performance of a webpage and provides detailed information on LCP, INP, and CLS scores. It offers both mobile and desktop performance metrics and highlights specific areas for improvement.

Screaming Frog SEO Spider

This tool is invaluable for SEO professionals, enabling them to crawl websites and collect data on various metrics, including Core Web Vitals. By integrating the PageSpeed Insights API, Screaming Frog can provide a comprehensive analysis of multiple pages simultaneously.

Google Search Console

While primarily used for monitoring a site’s overall health and performance in search results, Google Search Console also provides insights into Core Web Vitals. It offers a high-level overview of which pages are performing well and which need improvement.

Other Tools

Other useful tools include Lighthouse, WebPageTest, and GTmetrix, which can also be leveraged to gather additional insights and recommendations for optimizing Core Web Vitals.

Step-by-Step Audit Process

Now that we have the foundational knowledge and tools, let’s move on to the audit process. This structured approach will help us identify and prioritize issues affecting Core Web Vitals.

Step 1: Initial Assessment

Start by using Google PageSpeed Insights to get a baseline understanding of the performance of your website. Enter your website URL and analyze the results for both mobile and desktop versions. Take note of the current scores for LCP, INP, and CLS.

Step 2: Connect the PageSpeed Insights API in Screaming Frog

To perform a comprehensive audit across multiple pages, we can utilize Screaming Frog. Here’s how to set it up:

1. Open Screaming Frog SEO Spider.
2. Navigate to Configuration > API Access > PageSpeed Insights.
3. Enter your API key from Google and save the settings.

Step 3: Crawl Your Website

Input your website’s URL into the Screaming Frog interface and start the crawl. Wait until the crawl completes, which may take a few minutes depending on the size of your website.

Step 4: Analyze the Data

Once the crawl is finished, you can review the PageSpeed tab within Screaming Frog to see the core metrics for each page. Focus on those that have poor scores in LCP, INP, and CLS.

Step 5: Identify Patterns and Prioritize Issues

Take a look at the data exported from Screaming Frog to find patterns. Are there specific types of pages (like blog posts or product pages) that consistently underperform? Prioritize these pages for optimization.

Step 6: Detailed Reporting

Create a detailed report outlining:

• The percentage of pages failing to meet Core Web Vitals thresholds.
• Specific issues affecting each metric.
• Recommendations for resolving these issues, including potential savings in load time or visual stability.

Step 7: Implement Changes

Work with your development team to address the identified issues based on your report. This might involve optimizing images, reducing server response times, or eliminating render-blocking resources.

Step 8: Post-Implementation Review

After the changes have been made, recrawl the website using Screaming Frog to see how the adjustments have impacted Core Web Vitals. Compare the new results with your initial assessment.

Step 9: Ongoing Monitoring

Regularly monitor your Core Web Vitals using Google Search Console and PageSpeed Insights to identify new issues as they arise and ensure that your site remains optimized.

Improvement Strategies for Core Web Vitals

Now that we have a clear audit process in place, let’s explore specific strategies to enhance each of the Core Web Vitals metrics.

Optimizing Largest Contentful Paint (LCP)

1. Image Optimization: Ensure that images are properly sized and compressed. Utilize modern formats like WebP for better compression without losing quality.
2. Lazy Loading: Implement lazy loading for images and videos to prevent them from blocking the initial rendering of the page.
3. Server Response Times: Optimize your server’s performance by reducing response times, employing efficient caching strategies, and utilizing a Content Delivery Network (CDN).

Improving Interaction to Next Paint (INP)

1. Optimize JavaScript: Minimize and defer non-essential JavaScript. Consider breaking down large scripts into smaller parts that can load asynchronously.
2. Reduce Main Thread Work: Analyze and minimize the work done on the main thread to ensure that user interactions can be processed quickly.
3. Utilize Web Workers: Offload intensive calculations to web workers to keep the main thread free for user interactions.

Enhancing Cumulative Layout Shift (CLS)

1. Specify Dimensions for Media: Always set width and height attributes for images and videos to prevent layout shifts as they load.
2. Avoid Inserting Content Above Existing Content: Ensure that new content (like ads or pop-ups) does not push existing content around unexpectedly.
3. Use CSS for Layout Stability: Implement CSS styles that maintain the layout structure, such as using fixed dimensions for elements that may cause shifts.

Monitoring and Maintenance

To sustain optimal performance, it is essential to regularly monitor your Core Web Vitals. Implement real user monitoring (RUM) tools to gain insights into how actual users experience your site. This will help you identify issues that may not be captured in lab-based tests.

Moreover, stay informed about updates from Google regarding Core Web Vitals and related algorithm changes. Regularly revisiting your audit process will ensure that your site continues to meet performance benchmarks and provide a seamless user experience.

Conclusion

Understanding how to audit Core Web Vitals is not only essential for enhancing user experience but also crucial for maintaining a competitive edge in search rankings. With the right tools and a structured approach, we can identify performance issues and implement effective solutions.
