Our clients you’ve probably heard us talk about “on-page vs. off-page seo” at some point in the SEO process

I know we love to talk a bit more about specific on-page SEO aspects, but it’s still very valuable to understand some of the more technical parts that we might not be thinking about every day; your core web vitals.

Now, it should be mentioned there are newer metrics that can be helpful in optimizing web pages. However, for the purposes of this post, we are only going to be focusing on the main three that Google focuses on at this time. A graphic showing web vitals on a phone and pc.

These vitals themselves aren’t a factor that can influence how a page will rank in Google. But, the experience a user has on a page is.

The three core web vitals Google focuses on are things that can make it easier or harder for site visitors to navigate and interact with your site. These vitals go by the names of “Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift”, and they can be some of your best friends or worst foes when improving SEO for therapists. So, today we are going to be discussing:

  • What each of these metrics are
  • How to spot issues with each metric on your site
  • How you can improve them on your site
  • And an upcoming change in March 2024 that will actually be changing one of these metrics entirely

Without further ado, let’s get into what you should first know about core web vitals.

Understanding Google and core web vitals

As I mentioned above, these vitals do not directly your rankings in Google. However, they do serve as guideposts. They can help you understand what may be affecting a given page on your site, and support creating a more optimized user experience. The better the user experience is, the more likely Google is to have a higher rank in the search results. This influence on ranking is only one of many other things that should be taken into account. Some of these other things can include the quality of your content, page authority, structured data, etc. 

Another important thing to take into account is the fact that these metrics can change over time as Google changes. At this time, these are the three main core web vitals. However, this isn’t set in stone and is actually in the process of changing, which we will discuss a bit later.

With that said, let’s talk about the first core web vital, the largest contentful paint. 

Core Vital 1: Largest Contentful Paint (LCP)

Largest Contentful Paint refers to a metric that measures the perceived loading speed of a web page. It specifically focuses on the moment when the main content that appears “above the fold” becomes visually complete and fully rendered for the user. This is a vital metric at this time because it ensures that visitors see meaningful content at the top of your page as quickly as possible. When it comes to what classifies as a “good” or “bad” score, you can expect:

  • Good: Load speed is 2.5 seconds or less
  • Needs Improvement: Load speed is between 2.5 and 4 seconds
  • Poor: Load speed takes longer than 4 seconds

The elements of your page that are considered when calculating your score include things like images, videos, and text/font on your site.

Core Vital 2: First Input Delay (FID)

FID measures the time from when a user first interacts with a page to when Google actually starts responding to the input. This interaction can be in the form of the individual clicking a link, tapping a button, or other actions like key presses. FID focuses on user interactivity and responsiveness. A low FID indicates that a website is quick to respond to user input. This enhances the user’s sense of control and engagement. 

This is important because folks expect responsiveness on well-kept websites. If you click on a button and there is a major delay, it can be a frustrating, laggy experience that actually pushes more people away from your site than it attracts. Users expect sites to respond promptly to actions, and having a poor FID score can lead to higher bounce rates and less engagement/conversions on your site. Scores for FID generally look like the following:

  • Good: Load speed is 100 milliseconds or less
  • Needs Improvement: Load speed is between 100 and 300 milliseconds
  • Poor: Load speed takes longer than 300 milliseconds

Since this web vital is only measured when actions are taken, you can only measure it in the field. However, due to another newcomer in the world of web vitals known as INP, this may not be as important as it has been in the past. But, we’ll get to that in just a bit!

Core Vital 3: Cumulative Layout Shift  (CLS)

CLS is a measure of the largest burst of layout shift scores for every unexpected layout shift that occurs during the entire lifespan of a page. These layout shifts happen whenever a visible element changes position on the screen. The layout of a page can change for any number of reasons, but these shifts can be really annoying when users don’t expect it. It could cause folks to interact with the wrong elements on your site or lose their place on the page. Ensuring a stable visual experience means that these elements don’t move enough to disrupt a reader’s experience. The score for this metric doesn’t rely on time, but you can expect the following thresholds:

  • Good: Less than 0.1
  • Needs Improvement: Between 0.1 and 0.25
  • Poor: More than 0.25

How to Spot Core Web Vital Issues

In order to identify your CLS score along with the other core web vitals, it is best to use tools that will take live data of your site and give you immediate feedback. Some of these tools Google offers include the Pagespeed Insights tool, Google Search Console, and Lighthouse. Another option that may be helpful is CrUX, but this is a dataset that can be a bit more technical to access and understand. Each of these tools can provide helpful tips on improving each of these metrics. For the purposes of this blog, we won’t go into the specifics of each. But, we will go into a bit more detail on what you can do to improve each of these vital metrics.

Improving your LCP score comes back to making sure things like images, videos, and fonts aren’t taking up more space than they need to on your site. It means ensuring that you reduce the size of images, embed videos when possible, and only use web fonts intentionally to reduce the size of these elements on a given page. Issues with LCP can also be due to additional code added to your site. So, looking into plugins or other tools that can minify your code or space out the loading of your page can be another great way to help improve your LCP. 


Your FID score is most often affected by the amount of Javascript that is used on your site. You can improve it by optimizing how JavaScript parses, compiles, and executes on a given page. This can be accomplished by breaking up longer tasks into smaller segments through code-splitting or deferring unused Javascript code.

It is good to know what to do to support the health of this metric. But, this will soon be changing in the next year with the introduction of the metric Interaction to Next Paint (INP).


Improving your CLS score can be done by doing things like adding dimensions (width and height) to things like the images and videos you have on pages. Doing so will ensure the browser can reserve that space for these elements when they are loaded again. You can also defer JavaScript to load non-essential files to help increase speed. Another important part of improving CLS is making sure it is eligible for back/front cache (bfcache). Bfcache keeps pages in browsers memory for a short period after you navigate away from a page. If you return to them, then they will be restored exactly as you left them. This means the fully loaded page is instantly available without any shifts which may be seen during load due to a variety of reasons.

The Upcoming Change: FID to Interaction to Next Paint (INP)

In March 2024, Google will actually be switching out FID for another metric known as Interaction to Next Paint. This is a new responsiveness metric that measures how quickly a page responds to user interactions. INP observes the latency of all interactions a user has made with the page and can provide a more accurate estimate of responsiveness than FID. With this in mind, here are the scores you can expect from this metric:

  • Good: Load speed is 200 milliseconds or less
  • Needs Improvement: Load speed is between 200 and 500 milliseconds
  • Poor: Load speed takes longer than 500 milliseconds

To improve INP scores, you will need to identify where the slow interactions on your site are occurring. Once this is done, you can work to optimize these interactions, which are broken down into three parts; the input delay, processing time, and presentation delay. We won’t get into each of these parts in this post, since it deserves its own spotlight!
