What Is Largest Contentful Paint?
Largest Contentful Paint is a Core Web Vitals metric that enables web developers and technical SEO specialists to approximate the loading time of a web page’s main content and gain visibility into its rendering process.

LCP is set to be a ranking factor. As such, it is crucial to understand what is Largest Contentful Paint and how to improve LCP to upgrade your technical SEO services and achieve the best scores.
To better comprehend the question of what does LCP mean in SEO and how it can affect your online ranking, let’s first discuss exactly what is the largest element on a web page.
What Is the Largest Element on a Web Page?
Google considers the above the fold content as the main content or the largest block level elements on a web page. Above the fold pertains to the content displayed without scrolling the page.
Now, to fully understand what is LCP, it is necessary to learn the block level elements definition and their significant role in calculating your LCP score.
Block Level Elements Definition
Block-level elements are any element, such as a block of text, slider or banner image, that occupy the entire horizontal space available and the vertical space equivalent to the height of its container. Web pages comprise different block-level elements that appear as the user scrolls down the page.
Whenever a page loads, the browser downloads and analyzes the HTML block level elements to build the Document Object Model (DOM) tree. This DOM tree contains all the block level elements HTML that determine your page speed and site performance.
Google uses the largest block-level elements to calculate real human interactions with your website. Keep in mind that LCP elements can change over time as the page loads. Numerous variables, such as a user’s choice of browser, device’s operating system (OS) and browser toolbars, can affect how the block level elements are displayed.
To achieve a good LCP score, you have to be more aggressive in mastering what is LCP and how to improve it, especially for mobile because mobile pages tend to load longer.
Why Does LCP Matter to the
Page Experience Update?
Understanding LCP meaning is crucial because page speed and performance are the difference between a profitable business and a company in the red.
More than 53 percent of mobile users will leave if a website doesn’t load within three seconds.
As your page load time goes from 1 second to 3 seconds, your bounce rate also increases by 32 percent.
If HTML block level elements don’t render within seconds upon users’ query, your page visitors and potential customers are likely to leave and move on to faster-loading websites.
Failure to balance the size of your CSS block level elements and HTML block level elements can result in a poor LCP score.
Optimizing the block level elements in HTML helps Google bots crawl a website fast.
In terms of technical SEO, the faster the HTML and CSS block level elements load, the better user experience you create from a visitor standpoint.
