Google’s Core Web Vitals (CWV) are a set of user experience metric for websites. It tracks the speed at which content is loading on your page and the speed with which users can interact with it. It also measures how many times users can see content load before seeing a load indicator.
If you’re wondering how to measure core web vital metrics, don’t worry, we have got you covered. In this blog, we will cover everything you need to know about core web vitals. We will cover what core web vital metrics are, do they affect search ranking, and how you can optimize for them. But first things first, let’s talk about Google Announcement of how it’s now being used as a ranking factor.
Overview of Google’s Core Web Vitals Announcement
Back in November 2020 Google announced that page experience signals would be included in the ranking factors for websites on a Google Search. This actually started rolling out in May 2021 making it a global rollout by the end of August that year.
This update aimed to ensure that the results Google was providing to it’s users, provided a smooth experience when they visit those pages. These metrics go further than just page speed itself but dive into various technicalities of how the page responds in certain ways. The article can be read here for the full detail.
With that done and said, let’s dive into what these actually are and how you can improve them.
What are Core Web Vitals?
Core web vitals are a set of metrics that measure the speed and user experience of your page. These metrics include:
– Largest contentful paint: This measures how long it takes for the largest element on your page to load.
– First input delay: This measures how long it takes for users to be able to interact with your page after they first load it.
– Cumulative layout shift: This measures how much content shifts around on your page while it’s loading.
Why Are Core Web Vitals Important?
Core web vitals are important because they help webmasters understand how their content is performing and how they can improve performance. These metrics can also help webmasters improve their content and marketing strategies to deliver better results for users.
What Happens if My Page Has a Poor Core Web Vital Score?
If your page has a poor core web vital score, it may be ranked lower in search results. Additionally, your page may load slowly or experience other problems that impact the user experience.
Largest Contentful Paint
The LCP metric measures the time it takes for the largest content element to load on a page. It is an important indicator of how quickly your website is loading and can help you identify any performance issues. To improve this metric, you should optimize your images and reduce the number of redirects and server requests. By optimizing your images and reducing the number of redirects, server requests, and CSS files, you can speed up page load time and enhance the user experience.
You can also use caching and compression techniques to reduce loading times. By implementing these best practices, you can speed up page load time and make your website more accessible to users.
Cumulative Layout Shift
The cumulative layout shift score (CLS) is used to calculate the number of unexpected layout shifts that occur when loading a page. It scales the time it takes to load a page from 0% to 100%. A low CLS score indicates that there are fewer layout shifts compared to other web page loads. This reduces page loading time while maintaining a good user experience.
Additionally, it’s vital to monitor page performance and identify areas of improvement to optimize loading speed and reduce CLS scores. By optimizing your Core Web Vitals, you can improve user experience (UX) and increase user engagement.
First Input Delay
First input delay (FID) is one such metric and measures the time it takes for users to interact with your website after it has loaded. To improve first input delay (FID), you can optimize page loading speed by reducing the size of images, minifying code, and using a reliable content delivery network. Other techniques include ensuring that there are no render-blocking JavaScript files, as well as optimizing caching strategies. Using tools like Google PageSpeed Insights (Also known as Lighthouse) can help you measure and monitor your core web vital metrics performance over time.
Other Notable Metrics for Core Web Vitals
First Contentful Paint (FCP)
First contentful paint (FCP) measures the time it takes for the browser to render the first piece of content on a page. To improve first contentful paint, you can optimize your server response time, load above-the-fold content first, and reduce JavaScript execution time. Eliminating render blocking resources can also help speed up FCP.
Interaction to Next Paint (INP)
Interaction to next paint (INP) is the time it takes for users to interact with a page after the first contentful paint. To reduce INP, you can load core resources first, minimize JavaScript execution time, and optimize CSS delivery. Reducing the number of HTTP requests can also help speed up interaction to next paint times.
Time to First Byte (TTFB)
Time to first byte (TTFB) measures the time it takes for the browser to receive the first byte of data from the server. To reduce TTFB, you can optimize your server response time, use a content delivery network, and minify resources. Reducing the number of HTTP requests can also help speed up TTFB.
Total Blocking Time (TBT)
Total blocking time (TBT) is the cumulative time it takes for all page content to load and become usable. To reduce TBT, you can optimize your server response time, load core resources first, minimize JavaScript execution time, and optimize CSS delivery. Reducing the number of HTTP requests can also help speed up total blocking times.
Do the Core Web Vitals Affect SEO?
But do the core web vital metrics affect search engine ranking? In short, yes they do. The core web vital metrics can lead to improved user experience and better user engagement. These can positively impact the search engine ranking factor. However, it’s important to note that there is no single right answer to this question. It depends on the context of your website and how you conduct your marketing efforts.
How do you measure Core Web Vitals?
To measure Core Web Vitals, you can use web development tools to analyse and identify specific areas of improvement. Common metrics for web page speed include the page load time and page load error rate. In web page performance optimization, you should track metrics such as the first paint time (FCP), paint time (INP), paint delay time (FID), and paint jitter time (CLS).
You can also optimize images by reducing JavaScript usage, optimizing server response times for faster-loading pages, and using content delivery networks (CDNs) such as bunny.net to improve page speeds. By using web performance optimization techniques, you can increase user page experience and improve search engine ranking.
Core Web Vitals Assessment in PageSpeed Insights
To assess the core web vitals for a specific website, it is vital to regularly monitor page speed performance and make adjustments if necessary. For example, you may want to reduce page content or increase page speed to improve performance. Additionally, PageSpeed Insights provides tips on how to improve your core web vitals score.
Core Web Vitals Report in Google Search Console
The Core Web Vitals report in Google Search Console is a vital tool to measure the performance of your website against the Core Web Vitals metrics. It will provide data about the loading speed and interactivity of your page, as well as identifying any potential issues. By comparing your performance to other websites in your industry, you can identify areas for improvement and make necessary adjustments to better meet user needs. Taking this data into account will allow you to continuously improve your website’s performance and ensure that it continues to meet user needs.
How do you Optimize for the Core Web Vitals?
To optimize web vitals, it’s vital to monitor your website’s performance with the core web vital metrics. These include load time, page speed, and user experience. Ideally, these metrics should be optimized across the board so that users experience a seamless experience while browsing your website. It is vital to identify and fix any issues that could be affecting web vital scores, such as server errors or slow loading times. This will ensure that the web vital metrics are accurate and reflective of your website’s performance. It is essential to use images and other media appropriately to reduce loading times. This will help users experience a pleasant experience while browsing your website. Finally, it is vital to make sure all third-party scripts are up to date and properly configured for optimal performance.
Analyzing and Debugging LCP
To analyze and debug your largest contentful paint, you first need to identify what is causing the issue. This can be done by using web vitals report in Google search console or using a page speed tool such as Pingdom. Once you have identified the issue, you need to fix it so that your page loads faster.
How to Improve LCP Time
When it comes to optimizing the performance of your website, minimizing the size of web page and image can help speed up loading time. Deferring loading of non-essential resources such as JavaScript and CSS can also help speed up page load time. Optimizing server response time is vital for improving LCP performance. Using content delivery networks such as CloudFlare and Google’s CDN can help speed up page load time.
For best performance, make sure your website is optimized for mobile devices by using responsive web design and developing with user experience in mind.
Analyzing and Debugging CLS
It’s vital to analyze Core Web Vital scores to identify areas of improvement. First, audit your current Core Web Vital scores to see where improvements could be made. For example, if your page has an excessive cumulative layout shift (CLS), this means that the page content is changing significantly from one browser window to another. This can result in a poor user experience and slow page speed.
To reduce this problem, you can use techniques such as lazy loading and minification to minimize the amount of content on a page that needs to be loaded before it is displayed. Additionally, test the results of your changes with Chrome DevTools and online tools like PageSpeed Insights. By monitoring your Core Web Vital scores over time, you can ensure that your performance remains at its best.
How to Fix CLS Issues
When loading web pages, it’s vital to reduce page size and image sizes to improve loading speed. This can help reduce the time it takes for web content to load, making for a smoother user experience. Additionally, browser caching and minification of files can help to reduce page load time and avoid large blocks of text on a page as this could delay page load time too. Also, lazy loading of content is an effective way to defer non-critical content until it is needed. By following these tips and implementing web metrics optimization practices, you can ensure that web content is optimized for improved performance and user experience.
Analyzing and Debugging FID
FID, or first input delay, measures how quickly a page responds to user input. It is one of the three core web vital metrics. To improve performance, it’s important to analyze your website’s code and debug any delays in response time. For example, you can prioritize certain actions on the page such as loading critical resources first and optimizing JavaScript execution. Another way to speed up page load time is by caching certain content. For example, if you’re loading content from a server that’s geographically close to you, you can temporarily store the data on your local hard drive instead of performing a network request.
You should also look into other optimization strategies like using resource hints like preconnect and dnsprefetch to help with page load times. Ultimately, it takes time and effort to streamline page performance, but with a little patience and persistence, you can speed up your website’s performance and ultimately improve user experience.
How to Fix FID Issues
One of the main reasons web page performance issues arise is due to content delivery delay (CDD). This can be caused by a variety of factors, such as server load, page layout, and content loading time.
The first step in fixing web page performance issues is to reduce the size of your JavaScript and CSS files. These files are responsible for loading content on the page, so reducing the file size will speed up page load time. Also, you should minimize the number of requests to your server. One request is made for each element on a page. By minimizing these requests, you will speed up page load time. To optimize images for faster loading times, use image optimization tools like ImageOptim or Smush Pro.
Finally, utilize caching and pre-fetching techniques when appropriate. This includes using web browser caching functions or scripts that preload content on the page before it’s requested from the server.
Core Web Vitals and Content Management Systems (WordPress, Wix, Shopify, Squarespace)
If you use a content management system (CMS) such as WordPress, Wix, Shopify, or Squarespace, there are core web vitals plugins available that can help improve page speed and performance. For WordPress sites, Jetpack is one plugin that includes features to speed up loading times. Another popular plugin is WP Rocket which offers caching and file optimization features to help improve performance.
For Wix sites, there’s the Wix Speed Booster which optimizes images and minifies JavaScript and CSS files to speed up page load time. And for Shopify stores, there’s the Shopify speed optimization guide which provides tips on how to speed up your shop’s page loading time. Finally, you can speed up your Squarespace site by following the performance best practices outlined in their documentation.
