Is Core Web Vitals a Ranking Factor for Search Engines like Google, and Bing?

December 7, 2023

Yes, Search engines like Google and Bing consider Core Web Vitals as an essential ranking factor. These vitals are part of page experience signals, which provide user-experience performances based on a page’s loading performance, interaction with users, and visual stability.

It is confirmed by Google that page experience signals play a crucial role in search engine rankings. Websites with improved core web vitals may see improvements in their ranking.

What are Core Web Vitals?

Core Web Vitals was introduced by Google on May 28, 2020, and within June it became a part of Google Ranking Signals.

As a subset of Web Vitals, Core Web Vitals facilitates a unique pattern of user experiences as each vital focuses on a different aspect and reflects how users perceive and interact with a site.

Three Core Web Vital Metrics:

Core Web Vitals are classified into three metrics:
Largest Content Paint (LCP)

It measures how long it takes for the website to load the largest image or block of text in the viewport.

First Input Delay (FID)

It measures the response of the browser when a user engages with a page, such as tapping on the screen, clicking a button, etc.

Cumulative Layout Shift (CLS)

It focuses on the visual stability of a page and ensures the content quality (font sizes, image quality, size, etc.) doesn’t shift when elements are loading. For example, the font, and image size on a window screen won’t look the same in a smartphone.

According to, Interaction to Next Paint (INP) is going to replace FID as a Core Web Vitals metric in March 2024.

What is INP?

Interaction to Next Paint (INP) is a core web vitals metric that accesses the overall responsiveness of a page when a user interacts with a page. It checks factors like the latency of a tap, click or when someone typed from their keyboard. The unique fact is it analyses the user interactions that occurred throughout their lifespan on a specific page.

Are INP and FID the same?

First Input Delay (FID) is a measure of how responsive a website is when you first interact with it. This interaction could be a click, tap, or any other action you take on the site. FID specifically looks at the delay between your initial action and the website’s response.

In simpler terms, FID tells you how quickly a website reacts when you try to do something on it for the first time, giving you an idea of how smooth and responsive your experience will be. A lower FID means a more responsive website, while a higher FID suggests a potential delay in the site’s responsiveness.

Interaction to Next Paint (INP) includes all the delays including Input Delay, Processing Time, and Presentation Delay, giving you a clear picture of what makes a website delay in responding to a user interaction.

Input Delay is the time spent on the website waiting for some background tasks to finish. This can prevent the event handler from acting as per the user’s interaction.

Note: Event handlers are pieces of code that respond to specific events or interactions on a webpage. In simpler terms, they’re like functions that get triggered when something happens, such as a user clicking a button, typing on the keyboard, moving the mouse, or other actions.

Processing Time is the time it takes the website to execute event handles in JavaScript.

Presentation Delay is the time dedicated to managing queued-up interactions, readjusting the page layout, and painting the content (visually updating the content on the webpage).

INP less than 200 milliseconds is good and acceptable, while over 500 milliseconds is considered poor and can affect user interaction, ultimately affecting search engine ranking.

However, when it comes to ranking and organic results, content and relevance still matters. If Website B offers better user experience, but website A offers have better relevant information to people queries, then Google will still prefer A compared to B. So, core web vitals is a crucial part of your technical SEO. When done right, along with local SEO and standard SEO, it can do wonders for your website, checking all ticks in the boxes for google ranking.
