What are Core Web Vitals?

Core Web Vitals are the vital signs of a website’s performance, the essential metrics for every website. They tell you exactly what is happening with your audience and become the guiding light in building a strong web presence for your website.

These metrics help further distinguish between healthy, growing businesses and their less-successful counterparts by determining the website’s health, growth and overall user satisfaction.

What are the Major Segments of Core Web Vitals?

Rather than a single component, core web vitals should arguably be thought of as multiple components of a core web performance strategy. Each decision will affect many other decisions in your architecture and design.

Below are the major segments of core web vitals.

First Contentful Paint

First Contentful Paint (FCP) is the term used in web performance to talk about how long it takes for the browser to display something on the screen.

In other words, it’s the point at which “something” becomes visible. But what that “something” is can vary depending on the page and browser you are using, making this a slightly slippery metric.

FCP measures how long after hitting enter that anything actually shows up in your browser window. The goal of optimising this metric is to render the page’s visible content as quickly as possible, in order to give the user the impression that the page has loaded instantly. Contact SEO Brighton today on 01273 424 004 if you want this metric optimised for your website.

Speed Index

Speed Index is a new section of mobile user experience metrics. Speed Index reflects both the page loading time and the perceived speed of your webpage during the loading process.

It’s a fraction of seconds that reflects how quickly a web page responds to an action — especially compared to flashier and more disorienting solutions like pre-caching, social integrations or infinite scrolling.’

For example, let’s consider a simple website with 50 images on it. Based on the Google website’s loading time of 1.58 seconds, it would receive a ‘B’ grade. However, this is far from the truth.

If all 50 images were visible in the first 10 seconds of load time (as is the case for many websites), this site would not receive such a high grade since it only takes 1 second for the remaining images to load afterwards.

Largest Contentful Paint

Largest Contentful Paint is a website performance metric that reflects the largest size of the content appearing in the initial viewport before any user interaction occurs.

It is similar to measuring the download size for an image, except instead of recording the image bytes transferred across the Internet, it records the bytes loaded in the browser window as an image rendered by combining all elements on a given web page.

The Largest Contentful Paint metric reflects how much data your users must download in order to see your site’s most important content, like your primary navigation and highest-level headline text.

Time to Interactive

Time to Interactive or Time to I is an indication of how quickly a page takes to become interactive.

Time to Interactive (TTI) is defined as the amount of time it takes for a user’s browser to fully load all elements on the page and for the user to be able to interact with those elements.

TTI takes into account both DOM (Document Object Model time) and the various redirects that may take place.

Total Blocking Time

Total Blocking Time is the time needed to download, render and evaluate the page in order for it to become functional. In this regard, it is the critical first step of any page load but Total Blocking Time does not include the total load time of all resources on the page.

Time spent on your page is absolutely critical. Anything that detracts from your customer experience means lost sales. With Better Page Speed, you can speed up the delivery of content and resources, saving time to do what matters most ­– provide great experiences for your customers.

Cumulative Layout Shift

It is known that a single change to the structure or appearance of a page can negatively influence how users perceive its topic, organisation, and overall quality. Cumulative Layout Shift (CLS) is a measure of the total effect of these individual changes.

There are a lot of steps to take in order to make sure your website is performing well, but there’s no need to overcomplicate things. Optimising for core web vitals will help you rank higher and get more traffic without any hassle.

Why Should I Care About My Core Web Vitals?

Your website is the center of your online universe. It’s the first impression that you make on anyone interested in learning who you are, what you do and how they can get involved with you. All the parts and pieces of your online presence (social media, email, reputation management, etc.) should reinforce an overall theme that reinforces what people will read about you if they explore your site.

Core web vitals are important factors that contribute to websites success or failure, and will ultimately determine who gets marketed to, how they feel about your site, and whether they buy from you or not. They help improve your conversion rate. Call us today on 01273 424 004 to see how we can help you.

How Can I Improve My Core Web Vitals?

Web Vitals are an aggregate of key metrics that measure how your site is performing from a visitor’s perspective.

By focusing on improving these essential metrics, you can begin to upgrade the overall quality of your site and its ability to attract new traffic, convert visitors into leads or sales and retain repeat visitors.

Below are some good ways that core web vitals can be improved.

Reduce JavaScript (JS) Execution

You can improve your core web vitals by reducing the amount of JavaScript being run by each page. Page weight, additional resources, and time to first byte are factors that affect your site speed.

Front-end performance can be improved by reducing over-use of JavaScript (especially inline JS), creating static HTML files for some or all of a site, and eliminating unnecessary scripts or stylesheets from the header.

Implement Lazy Loading

Implementing lazy loading on your website is a fantastic way to improve your web metrics. Lazy loading means you can load larger images and data groups only when they become visible to the user. This reduces the amount of time it takes for page content to begin loading, which in turn improves performance times.

Once the page is fully loaded, any images that have been lazy loaded will be visible in the viewport and able to be seen. Call SEO Brighton today to implement this feature.

Optimise and Compress Images

The key to a smooth experience for users on a slow connection is ensuring that your page loads with the bare minimum of resources, as quickly as possible.

Images and videos can make up a large proportion of bandwidth, and it’s likely that you could shave off seconds from your page load by optimising and compressing them.

Providing Proper Dimensions for Images and Embeds

Providing proper dimensions for images and embeds, using extensions such as MW Extension:Dimensions, can help ensure that your viewers don’t have to scroll to see each image clearly. Really long pages that require scrolling can have a negative impact on visitor engagement.

Properly sized images/embeds are a great way to show that your site is designed responsively. SEO Brighton can help you achieve this. Get in touch today by dialing 01273 424 004.

Improving Your Server Response Time

It’s no secret that your website’s performance is a key ranking signal for search engines. A faster site can lead to more searches and increased brand awareness. Studies have shown that a 1-second delay in page response time could result in a 7% reduction in conversions.

The server response time is the time it takes for your server to respond after receiving a request. The faster your server responds, the more user-friendly and enjoyable your site is. Cutting down on the response time of your server can improve a noticeable amount of factors in loading and using a website.

How important is Page Speed for SEO?

A lot. It’s very important to Google. If your website isn’t loading quickly, you cannot expect to rank well in Google for competitive keywords.

To rank in search results on Google, your page must load quickly. The bigger the bandwidth speed of your site, the faster pages will load and the higher you’ll rank.

Google has apparently said on many occasions that they rank sites with faster load times higher in their search results.

Does CLS affect SEO?

Yes, but not in the way that you might think. High CLS (Cumulative Layout Shift) can be an indication of low-quality content since it is often a product of thin and repetitive design.

On the other hand, marginal amounts of clintext (CLS) can bring long-tail traffic to competing content and sitewide links. On the flip side, one thing that is clear is that overly optimized pages with excessive content distributed throughout sub levels receive lower rankings than those that have only a few instances of vital content.

Many webmasters do not take cognizance of the fact that even low position changes can significantly impact CTR. This is especially true for small websites or blogs where a seemingly small drop in position could possibly wipe out traffic.

What causes the First Input Delay?

If you’ve ever noticed a slight but still annoying delay between pressing a key on your keyboard and seeing a letter appear on-screen, then you’ve experienced the First Input Delay.

The first input delay is caused when most browsers block any JavaScript, CSS, images or other assets which are loaded while the user types into the input fields.

This prevents unintended actions like changing tabs while the user is still typing. By default most browsers will only load a few characters of text before it triggers the FID.

Why is FID important?

Imagine how frustrating it would be to interact with a computer that made you wait when you pressed a key. It feels slow because you’re expecting results instantly. But what if waiting for three-plus seconds wasn’t part of the deal?

So therefore, FID is important because web performance is a critical aspect of the user experience. With a shorter FID, users perceive the page to have responded quicker. This leads to better conversion rates and higher revenues for Online merchants.

Does LCP affect SEO?

Yes. Largest Contentful Paint (LCP) does.

When your page is being built it is painted in real-time onto the screen of the visitor’s web browser. If you have large images on your page, if there is a lot of whiteness caused by the lack of content or if your site is very slow to load, you will get a larger LCP percentage.

This can be interpreted as slower loading overall for the webpage and search engines look at every aspect of your page when indexing.
