If you're a website owner or an SEO specialist, you may have heard about the term "core web vitals." In 2021, Google announced that they would include Core Web Vitals in their ranking algorithm. This means that core web vitals have become essential in determining a website's ranking on search engine result pages (SERPs).
What are core web vitals, and why are they important for SEO?
Core web vitals are a set of user experience metrics that measure how fast a web page loads, how quickly users can interact with the page, and how stable the page is as it loads.
Core web vitals are important for SEO because they are a key factor in determining the user experience of a website. A website that loads quickly, is interactive, and has a stable layout is more likely to provide a positive user experience than a website that takes a long time to load, is unresponsive, and has a layout that constantly shifts.
A positive user experience is crucial for SEO because it encourages users to stay on the website longer, engage with the content, and share it with others. A website that provides a positive user experience is also more likely to attract links from other websites, which can improve its ranking on SERPs.
In addition to improving user experience, optimizing for core web vitals can also help improve website performance. By reducing the page load time, optimizing the layout, and making the website more interactive, website owners can improve their website's speed, which can improve their ranking on SERPs.
How is my web vitals score determined?
Your website will be graded based on three primary metrics:
Let’s take a look at what each of these actually means and how you can improve your score in each area.
Largest Contentful Paint (LCP): this measures the loading performance of a web page. It measures the time taken for the largest content element (such as an image or text block) on the page to load.
The following optimizations are recommended to improve your LCP score:
- Optimize images: reduce the file size of images to speed up their loading time.
- Use a Content Delivery Network (CDN): a CDN can help distribute the content across multiple servers, reducing the loading time.
- Optimize the server response time: make sure your server responds quickly to requests, as this can also affect the LCP.
First Input Delay (FID): this measures the time a web page takes to respond when a user interacts with it, such as by clicking a button or a link.
These optimizations can help improve your FID score:
- Optimize event handlers: make sure event handlers are efficient and not causing delays.
- Use a faster server: a faster server can reduce the time it takes for a user's input to be processed.
Cumulative Layout Shift (CLS): this measures the visual stability of a web page. It measures how much the page layout shifts as it loads.
CLS optimizations should include:
- Specify image and video dimensions: this can prevent layout shifts caused by the loading of media files.
- Reserve space for ads and embeds: preallocate space for ads and embeds to prevent layout shifts when they load.
- Avoid inserting content above existing content: this can cause layout shifts, so make sure to insert content below existing content.
How can you optimize for core web vitals?
Optimizing for core web vitals involves several factors, including optimizing images and videos, improving server response time, reducing render-blocking resources, and minimizing layout shifts. Google has provided a set of tools to help website owners and SEO specialists optimize for core web vitals, including the PageSpeed Insights tool and the Search Console Core Web Vitals report.
To optimize for core web vitals, you can consider the following steps beyond those we’ve already looked at in the section above:
- Optimize images and videos by compressing them, reducing their size, and using the appropriate file format.
- Improve server response time by using a Content Delivery Network (CDN), optimizing your server configuration, and reducing the number of requests made to the server.
- Minimize layout shifts by ensuring that content does not shift unexpectedly during page load or user interactions, optimizing font loading, and reserving space for ads and images.
- Use Google's tools, such as the PageSpeed Insights tool and the Search Console Core Web Vitals report, to measure your website's performance and identify areas for improvement.
By optimizing for core web vitals, you can improve user experience and increase your website's ranking on search engines, leading to increased traffic and engagement.
In conclusion, core web vitals are an essential factor in determining a website's ranking on SERPs. By optimizing for core web vitals, website owners and SEO specialists can improve the user experience of their website, attract more links, and improve their website's speed and performance.
