How do I check Web vitals?
Run Lighthouse to audit a page to get page-level guidance and use the Web Vitals extension to analyze Core Web Vitals in real time. Use the performance tab in Chrome's DevTools to debug performance issues and test code changes.
The Core Web Vitals report shows how your pages perform, based on real world usage data (sometimes called field data). You can read more about this initiative on the Google Search Central blog. Longer page load times have a severe effect on bounce rates.
Core Web Vitals are a set of standardized metrics from Google that help developers understand how users experience a web page. While Core Web Vitals were created for developers, these tools can be used by all site owners because they break down the user's real-world experience on a page.
The Core Web Vitals (CWVs) are three web performance measurements that impact where a website shows up in search engine results: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).
Overview. The web-vitals library is a tiny (~1K), modular library for measuring all the Web Vitals metrics on real users, in a way that accurately matches how they're measured by Chrome and reported to other Google tools (e.g. Chrome User Experience Report, Page Speed Insights, Search Console's Speed Report).
Page 2 is where the forgotten content and websites go to die. The average web user never goes past the top 5 listings on a search result, more than 70% of all clicks goes to these top 5 results. And that doesn't include the paid results we find at the top of the page.
An experience report is a presentation by a person on the subject of work that was done in real life and with a practical goal. The presenter is a practitioner, involved in doing the work that is described in the report.
Intrusive interstitials are essentially popup ads. They tend to block most or all of a page, leading to a bad user experience for desktop and mobile users alike. Google's own examples of intrusive interstitials. These types of ads make it frustrating at best to access the page as intended.
In short, Core Web Vitals are a subset of factors that will be part of Google's “page experience” score (basically, Google's way of sizing up your page's overall UX). You can find your site's Core Web Vitals data in the “enhancements” section of your Google Search Console account.

Technical SEO refers to website and server optimizations that help search engine spiders crawl and index your site more effectively (to help improve organic rankings).
CLS (Cumulative Layout Shift): The amount that the page layout shifts during the loading phase. The score is rated from 0–1, where zero means no shifting and 1 means the most shifting. This is important because having pages elements shift while a user is trying to interact with it is a bad user experience.
Largest Contentful Paint (LCP) measures loading, First Input Delay (FID) measures interactivity while Cumulative Layout Shift (CLS) measures visual stability. Source. Note they're not the only signals that make up Page Experience.
E-A-T stands for Expertise, Authoritativeness, and Trustworthiness. The concept comes from Google's Search Quality Rater guidelines and it became well known after the infamous Medic Update in August 2018. E-A-T is one factor that Google uses to evaluate the overall quality of a web page.

Largest Contentful Paint (LCP) is an important, user-centric metric for measuring perceived load speed because it marks the point in the page load timeline when the page's main content has likely loaded—a fast LCP helps reassure the user that the page is useful.
Core Web Vitals are important for SEO, as they can help give your website more recognition and keep it organized and clean. These vitals can help improve your website's visibility and ranking in browsers, as well as give your audience a hassle-free experience while browsing your page.
Do people click past the first page of Google?
First Page Compared To Later Pages
According to Moz, the first page of Google captures 71% of search traffic clicks and has been reported to be as high as 92% in recent years. Second-page results are far from a close second coming in at below 6% of all website clicks.
According to multiple studies, only 25 percent of users go to the second page of search results. That means 75 percent of users stick to the first page of search results.
Google's algorithm does the work for you by searching out Web pages that contain the keywords you used to search, then assigning a rank to each page based several factors, including how many times the keywords appear on the page.

Interstitials are pop-up content which will appear once a website has loaded for users. While these can be useful, they may also cause long-term UX issues as well as affect how search engines are able to crawl a website.
Interstitials are overlays on the whole page and dialogs are overlays only on a part of the page, sometimes also obfuscating the underlying content. Websites often need to show dialogs for various reasons; however, interrupting users with intrusive interstitials may frustrate them and erode their trust in your website.
Interstitial ads are full-screen ads that cover the interface of their host app. They're typically displayed at natural transition points in the flow of an app, such as between activities or during the pause between levels in a game.
Core Web Vitals is a set of metrics introduced by Google that aim at helping you measure the quality of user experience on a website. The metrics themselves are a part of a larger set of metrics, Web Vitals, and are defined as the three most important metrics to measure the quality of user experience.
Core Web Vitals Report in Google Search Console
Google Search Console (GSC) has two new Core Web Vitals reports - one for mobile and one for desktop.
- Always include size attributes on your images and video elements, or otherwise reserve the required space with something like CSS aspect ratio boxes. ...
- Never insert content above existing content, except in response to a user interaction.
Is TBT a core web vital?
Total Blocking Time (TBT) is a non-Core Web Vital that measures the total time in milliseconds between First Contentful Paint (FCP) and Time To Interactive (TTI) where the main thread is blocked long enough to make it unresponsive to user input.
Optimize your images. On most websites, the above-the-fold content usually contains a large image which gets considered for LCP. It could either be a hero image, a banner, or a carousel. It is, therefore, crucial that you optimize these images for a better LCP.
What's a Good LCP Score. A good score means that LCP should be less or equal to 2.5 seconds. If so, the page will get the green score and pass the assessment. If LCP is between 2.5 and 4.0 s, the score “needs improvements” — you'll get an orange grade.
A page's FCP tells you how long it takes for the first text or image-based element to appear in a visitor's browser. LCP, as its name implies, measures the time it takes for the largest element to appear.
A layout shift occurs when a visible element on your page changes position or size, affecting the position of content around it. Sometimes the shift is intended, such as when a container expands as a result of a user action.
Cumulative Layout Shift (CLS) attempts to measure those jarring movements of the page as new content — be it images, advertisements, or whatever — comes into play later than the rest of the page. It calculates a score based on how much of the page is unexpectedly moving about, and how often.
First input delay (FID) measures the time from when a user first interacts with your site (i.e. when they click a link, tap on a button, or use a custom, JavaScript-powered control) to the time when the browser is actually able to respond to that interaction.
What is the difference between FID and TTI? While TTI and FID seem similar to one another, there are some critical differences in these metrics. Unlike FID, Time to Interactive only tells us how long it took for the page to become interactive, not the time to respond to user interaction.
Delays to the first user input are caused when the browser is busy downloading assets, parsing scripts, or executing blocking operations. The page appears unresponsive when the user interacts with a busy browser by either clicking or typing.
In short, Core Web Vitals are a subset of factors that will be part of Google's “page experience” score (basically, Google's way of sizing up your page's overall UX). You can find your site's Core Web Vitals data in the “enhancements” section of your Google Search Console account.
