First contentful paint (FCP) is a key performance metric used to measure the time it takes for a web page to load its first piece of content, such as an image or text. A fast FCP is essential for providing a good user experience and can also improve search engine rankings.

What is First Contentful Paint?

FCP is a performance metric that measures the time it takes for the browser to render the first piece of content on a web page. This can include text, images, or other media.

FCP is important because it is one of the first things that users see when they load a web page. If the FCP is slow, it can give the impression that the website is slow or unresponsive, which can lead to a poor user experience.

Why is First Contentful Paint Important?

In addition to providing a better user experience, a fast FCP can also have a positive impact on search engine rankings. In 2018, Google announced that it would start using FCP as a ranking factor for mobile search results. This means that websites with a fast FCP are more likely to appear higher in mobile search results than those with a slow FCP.

How to Reduce First Contentful Paint

There are several techniques that can be used to reduce FCP and improve website performance. Here are a few:

  1. Optimize Images: Images are often the largest files on a web page and can slow down FCP. To optimize images, use a tool like Photoshop or online services like TinyPNG or to compress and resize images.
  2. Minify CSS and JavaScript: Minifying CSS and JavaScript files can reduce their file size, which can improve FCP. Use a tool like UglifyJS or CSSNano to minify your CSS and JavaScript files.
  3. Use Browser Caching: Browser caching allows the browser to store files on the user’s device, so they don’t need to be downloaded again when the user visits the website again. This can improve FCP by reducing the amount of time it takes to download files.
  4. Reduce HTTP Requests: Each HTTP request made by the browser can slow down FCP. To reduce the number of HTTP requests, combine CSS and JavaScript files, and use CSS sprites to combine multiple images into a single file.


First contentful paint is an important performance metric that measures the time it takes for a web page to load its first piece of content. By optimizing images, minifying CSS and JavaScript, using browser caching, and reducing HTTP requests, you can improve FCP and provide a better user experience for their visitors.
