What are Core Web Vitals?

Over the past decade, Google has been encouraging business owners to focus on their website user experience, with particular attention paid to site speed. Because it’s a priority for Google, they monitor how quickly each website loads and use that as a factor for where a website ranks in search results. Google has solid reasons for drawing attention to website performance. A slow website has a significant negative impact on your ability to convert visitors into customers. According to Google: For every second delay in mobile page load, conversions can fall by up to 20%.

Now, Google is taking its commitment to user experience a step further. They have started tracking three specific metrics related to site speed and will add those to the list of search result ranking factors. The three factors are:

Largest Contentful Paint (LCP) – This measures when the largest content element at the top of a web page becomes visible. That content could be an image, a video, or a block of text. Essentially, it’s testing how quickly visitors can view a meaningful piece of content on a website.

Cumulative Layout Shift (CLS) – This measures how long it takes the various elements on a website to settle into place. If you’ve ever been reading an article online and something suddenly shifts: the text resizes, or a button moves right before you can click, then you’ve experienced layout shift. 

First Input Delay (FID) – This measures the time between a visitor first interacting with your site (e.g., clicking a link) and the website responding. Website visitors shouldn’t have long waits between clicking on links and the website reacting.

Google is calling these metrics Core Web Vitals (CWV), and they have announced that starting in June, a website’s score in each of these three areas will affect its search engine rankings.ย 

What does it mean for my SEO results?

While marketing bloggers are claiming that you need to update your website to meet Core Web Vital standards or face an SEO cataclysm, Google’s message has been consistent: this is a minor update.ย 

To put the change in perspective, keep in mind that the Core Web Vitals comprise just one of more than 200 ranking factors. Multiple comments from Google leaders have indicated that you should not expect a significant ranking shift from optimizing Core Web Vitals. We can’t say precisely how much these metrics will impact rankings, but it is unlikely that they will be significant ranking factors. 

So, while your website speed is important, it is only one factor in a compelling user experience.ย 

When should I check my Core Web Vitals?

There are cases where a website owner might want to give special attention to the Core Web Vitals score:

Websites in a highly competitive industry – If your business is heavily dependent on search traffic and competing against other highly optimized websites, improving the Core Web Vitals could be a chance for you to gain an edge.

Websites that load significantly slower than competitors – If your website is doesn’t meet Google’s standards for the three metrics, but all of your competitors’ websites do, you could see your search engine rankings dip.

Websites that provide a poor experience for potential customersย – Forget about Google for a moment: if your website is very slow, website visitors are likely leaving your website before they even see your content. Or they might get so frustrated that they have a poor opinion of your brand.

Where to Go From Here

If you are already adding a steady flow of compelling content to your website, your content is being shared and linked to on other websites, and your users are highly engaged on your site, then it would be worth spending time on things like Core Web Vitals. 

If your site isn’t reaching its peak performance in those more fundamental metrics, then there are better ways to allocate your resources.
