I am going to explain what First Contentful Paint and Largest Contentful Paint are. I will also cover what the differences are between FCP and LCP and why each metric is important for SEO and webpage loading speed.

Then you will learn a few tips about how to improve a site’s FCP and LCP. Keep in mind, these types of technical SEO fixes are not always easy to do or identify. Here are some tips.

What Is First Contentful Paint?

First Contentful Paint (FCP) is a web performance metric that measures the time it takes for the browser to render the first bit of content from the Document Object Model (DOM) after the user navigates to the page. This can be text, an image, an SVG, or a non-white <canvas> element. FCP is important because it is the first time that the user sees anything on the page, so it gives them an indication that the page is loading.

What Is Largest Contentful Paint?

Largest Contentful Paint (LCP) is another web performance metric that measures the time it takes for the browser to render the largest content element on a page. This is typically the main content of the page, such as a hero image, a large block of text, or a video. LCP is important because it is the first time that the user can see the main content of the page and interact with it.



What Are The Differences Between FCP and LCP?

  • FCP measures the time to render the first bit of content (“content” refers to text, images, including background images, elements, or non-white), while LCP measures the time to render the largest content element (“element” refers to an image or text block).
  • FCP is typically faster than LCP, since the largest content element is usually the last thing to load on the page.
  • FCP is more of a general metric, while LCP is more specific to the main content of the page.

Why Are FCP and LCP Important For SEO And Webpage Loading Speed?

FCP and LCP are both important for SEO and webpage loading times because they can affect the user experience. A slow FCP or LCP can make users frustrated and leave the page before it has loaded completely. This can lead to high bounce rates and low conversion rates.

Google uses FCP and LCP as part of their Core Web Vitals metrics that help show areas to improve website performance. This can mean that websites with good FCP and LCP scores could be more likely to rank higher in search results.
