Internet users are becoming increasingly impatient and tolerant of poorly performing services. Admittedly, this isn't surprising. After all, technology is consistently accustomed to ever-faster performance. Generally, everyone expects an immediate response to interactions. If a website is running too slowly, there are usually at least a few alternative resources available.
When running your own website, you must ensure a user-friendly experience to prevent potential customers from defecting to your competitors. Performance is key, and this is the FCP metric. This enigmatic acronym stands for First Contentful Paint. Learn how it affects your website and what you can do to improve your score.
What exactly is First Contentful Paint?
First Contentful Paint is a metric that measures the amount of time that elapses from the start of a page's loading until the first elements of content are displayed. Examples of such content include images, text, or vector graphics in SVG format. When a viewer sees content appear on the screen, they gain the confidence that the website is loading correctly and will soon be able to see it in all its glory. However, the role of FCP is not limited to aspects related to user experience. This aspect is also included in Google's ranking factors. Therefore, if you decide to promote your website through SEO , you should pay special attention to First Contentful Paint.
Why is FCP so important?
Skillful optimization of FCP issues on a website can result in the following benefits:
(The rest of the article can be found below the form)
- the user receives an almost immediate signal that the site is responding,
- reducing the likelihood of impatient recipients leaving the site,
- building trust in the website from the very first seconds,
- favorable evaluation of the website's quality by search engines,
- increased chance of expanding the website's visibility in organic search results,
- higher conversion rate,
- reduced bounce rate,
- overall improvement in the effectiveness of marketing and sales activities.
How to measure FCP?
- Google lighthouse – This plugin is available for Chrome users. It allows you to check various metrics related to website performance. You can also generate reports and view tips to improve your website's performance.
- PageSpeed Insights – This free tool allows you to analyze website performance on both mobile and desktop. Similar to Lighthouse, you get access to a variety of metrics, including FCP.
- WebPageTest – This advanced tool is designed for website performance testing. It allows you to generate detailed reports and run tests across various locations and devices.
- GTmetrix – this solution uses the PageSpeed Insights and Lighthouse mechanisms. While the interface itself seems simple, interpreting some parameters requires a bit of practice. However, a deeper understanding of this solution will allow you to obtain accurate data on website performance.
- Chrome DevTools – is a set of developer tools built into the web browser. This solution allows for detailed analysis of the loading times of individual website elements. However, due to its rather technical nature, it is recommended for more advanced users.
How to interpret FCP results?
There are several ranges that define a website's FCP performance. The individual thresholds are as follows:
- good: 0-1.8 seconds,
- needs improvement: 1.8-3.0 seconds,
- weak: over 3.0 seconds.
What influences the value of FCP?
The loading time of the first element on a website can depend on many factors. Learn which aspects can determine the result:
- server response time,
- server configuration,
- location of servers relative to users,
- hosting quality,
- size and structure of CSS files,
- impaired rendering of JavaScript resources,
- resource loading order,
- use of browser cache,
- image optimization,
- mechanism for loading multimedia content,
- graphics format,
- resource size.
How to optimize FCP?
A complex website structure can be a major obstacle to achieving a favorable FCP score. This includes CSS and JavaScript, which often load simultaneously and first. This results in a delay in displaying key modules that the user should see after starting a session. Therefore, it's important to simplify and compress the code used to improve loading. It also helps to move some resources to the bottom of the page, provided they aren't crucial to the initial view of the site. It's also worth reviewing the code and removing unnecessary fragments that can place excessive load on the server.
Various multimedia materials, such as photos and graphics, are often the culprit. If they haven't been properly optimized, they consume too many resources. Therefore, classic extensions like .png or .jpg should be replaced with more modern formats. WebP is an excellent choice, as it effectively reduces page load times.
Lazy loading is also recommended for embedded components on a website. This technique involves delaying the loading of images and visual elements that don't necessarily need to be visible in the initial view. This method allows the browser to gradually load subsequent content elements as the page scrolls. In practice, lazy loading serves to establish a hierarchy of priorities for loading individual resources.
The server's configuration is also important. The classic HTTP protocol is quite outdated and can cause website performance degradation. Therefore, it's worth implementing the HTTP/2 or even HTTP/3 standard. This will shorten the time required to transfer data between the server and the user's browser.
Remember that…
Working on improving FCP requires a series of rather technical steps. If you're not familiar with such activities, the entire process may seem like black magic. However, it's undoubtedly worth the effort. After all, what's at stake is both user experience and website visibility in the most popular search engines.
You can perform some tasks yourself. Free tools for analyzing website performance are available. Each tool offers specific suggestions for actions to take to achieve a better FCP score. For more demanding tasks, it's worth seeking the support of a reputable SEO agency. Website performance optimization is a daily task for experienced specialists. Therefore, you can entrust them with the most demanding tasks, leaving you free to focus on other business-related matters.
First Contentful Paint FAQs
FCP (First Contentful Paint), or the time to render the first element of content, is a key metric for website performance. It measures the time from the moment a user begins to load a page (e.g., clicks a link) to the moment the first element of content appears on the screen—be it a piece of text, a graphic, a logo, or even a vector graphic element (SVG).
FCP is responsible for the perceived page loading speed. It has enormous psychological significance for the internet user, providing immediate feedback that the server is working, the page is not "dead," and the loading process has actually begun. The faster the first element appears, the less likely an impatient user will defect to a competitor.
To ensure a good user experience (and score points in Google's algorithms), FCP should be 1,8 seconds or less. A score between 1,8 and 3 seconds indicates a page needs optimization, while anything above 3 seconds indicates a slow site.
While both metrics measure rendering time, they differ in when the timers stop:
- FCP measures the appearance of the first element on the screen (e.g. background or menu bar).
- LCP (part of Core Web Vitals) measures the time it takes to display the largest and most important element on a page (e.g., a large product photo or article headline), i.e. the moment when the page becomes truly readable to humans.
The main technical problems blocking the quick start of the website are:
- Long server response time (high TTFB rate),
- Render-blocking resources – heavy CSS and JavaScript files that the browser must download and process in their entirety before displaying anything to the user,
- Too much page code weight and lack of proper data caching.
FCP optimization focuses on removing technical barriers at the very beginning of the charging process. Key actions include:
- Reducing server response time (e.g. by changing to a faster hosting or implementing a CDN network),
- Postponing the loading of non-critical JavaScript and CSS styles until later (asynchronous),
- Code minification (cleaning it of unnecessary spaces and comments),
- Implementation of correct page caching.
