Core Web Vitals Checker

Core Web Vitals Checker

Lighthouse Core Web Vitals are metrics that Google uses to determine how good the user experience (UX) of your website domain is. Core web vitals have become a ranking factor in recent years, meaning that poor performance on these metrics could see your website struggle to be seen on search engine result pages. This is why it’s important to keep an eye on how your Core Web Vitals SEO score is performing with a Core Web Vitals check and do everything you can to optimise them in any way possible.

Google Page Insights Check

Our nifty tool is designed to analyse your website’s performance, using real Chrome data provided by the Google lighthouse tool to present your scores in various metrics in a clear way. This makes it easier to know where you need to improve and how to get an impressive Google Lighthouse SEO score.

What Are The Core Web Vitals

Core web vitals are three sets of metrics that are designed to measure the UX of your website. Since Google has become a more user-focused platform, these metrics have grown significantly and form a vital part of Google’s page experience signals, alongside mobile-friendliness, safe-browsing, and HTTPS security.

The main three Core Web Vitals are as follows:

  1. Largest Contentful Paint (LCP)
  2. First Input Delay (FID)
  3. Cumulative Layout Shift (CLS)

The LCP metric measures the time it takes for the largest asset on a webpage to load so that it is viewed fully and able to be interacted with. This essentially determines how quickly your website loads, as usually, the largest asset will be the last to be in view. LCP is a massive Core Web Vitals ranking factor.

The FID metric is concerned with how long it takes between a user interacting with your site and the website performing the desired result of that interaction. For example, FID could measure the time it takes from a link being clicked until the user is directed to a new page.

The CLS metric measures how stable the assets on your website are. When a webpage loads, some images and pieces of text may jump around the page during the loading process, with the most common reason for this happening being adverts pushing images and text down the page. Your CLS will inform you how volatile your page is, with a lower score being desirable.

Additional web vitals can be useful to track alongside these that our tool keeps an eye on. These are the First Contentful Paint, Total Blocking Time, Speed Index, and Time to Interactive, which first appeared in the Google lighthouse test.

How Our Core Web Vitals Tool Works

Our Core Web Vitals Tool is extremely straightforward to use from the end user’s perspective. To begin, all you need to do is input your domain URL and click our ‘Ask Google Page Insights API button’.

From there, our tool will collect data from the Lighthouse Core Web Vitals. However, what makes our tool better than a standard Google lighthouse audit is that you’ll be presented with a lot more information and useful tips to help you improve your scores.

When conducting our Core Web Vitals check, our tool will also perform a basic yet informative website audit, scoring your website in five different categories:

  1. Performance – This checks how well your website performs in terms of loading speed and functionality.
  2. Accessibility – This score checks how easy your website is to use, considering things such as your background to foreground contrast ratio, the navigation of your website, as well as how clear your buttons and labels are.
  3. Best Practices – This checks to see how safe and secure your website is and how well you follow the desired security measures of Google.
  4. SEO – This evaluates how well you’re implementing the advised SEO techniques, such as link building, the use of keywords, and more.
  5. PWA – These checks validate the aspects of a Progressive Web App.

All of these scores are presented out of 100, with anything over 90 being considered excellent, anything between 50-89 being okay, and scores under 50 highlighting an area that needs serious attention.

Each category will also inform you of where your website specifically failed and provide hints as to how to improve it in the future.

As well as this breakdown, you will also be presented with your core web vital scores. These will be colour-coded to aid with clarity.

How To Interpret Core Web Vital Scores

Each web vital has a range where you’d want your score to be, and for most, this range is unique from one another.

First Contentful Paint – This is the time it takes for a single asset to load properly on your website. You should be looking for a time under 1.8 seconds; however, as technology advances, that number is getting lower and lower.

Largest Contentful Paint – It’s advised that you try to get your LCP at under 2.5 seconds, as having users wait longer than that for your biggest asset to load may discourage them.

Total Blocking Time – This is the time between your first and largest asset being loaded. Ideally, this should be really snappy and be under 300ms, as suggested by a Google lighthouse speed test.

Time to Interactive – This is the time it takes for the page to become fully interactive. A Google lighthouse test online would say that anything under 5 seconds is good; however, if you want to perform better, your standards should be higher than this, with anything under 3 seconds being an excellent score.

Speed Index – This metrics shows how fast it takes for the content on your website to visually populate the page; however, it doesn’t mean that these assets can be interacted with yet. A Google Lighthouse docker would deem a score under 4.3 seconds as better than average.

Cumulative layout Shift – Presented as a decimal, a good score in this metric would be anything under 0.1, as this shows that your website’s assets are stable and won’t move around much.
