Brace yourself! :) Google's PageSpeed Insights tool is one of the most popular tools for measuring website performance. The tool provides insights into a variety of metrics, including lcp, fcp, cls, fid, inp, and ttfb. In this blog post, we'll explain what each of these metrics means and how you can use them to improve your website's performance.

LCP

Largest Contentful Paint, or LCP, is a page speed metric that measures the time it takes for the largest content element on a page to load. In order to optimize LCP, web developers can take several steps, such as reducing server response times, compressing files, and using browser caching. By taking these measures, developers can help improve page load times and create a better user experience. In addition, developers can also use tools like Google's PageSpeed Insights to measure LCP and identify areas for improvement. By making even small changes to improve LCP, developers can make a big impact on page speed and overall user experience.

FCP

First Contentful Paint (FCP) is a page speed metric that measures the time it takes for a page's main content to render. FCP is an important metric because it reflects how quickly a page can be usable for users.

There are various ways to improve FCP. One way is to optimize the order in which resources are loaded. If the most important resources are loaded first, then the page can start rendering sooner. Another way to improve FCP is to minimize the size of resources. This can be done by reducing the number of Bytes used by each resource, or by compressing resources so that they take up less space. By reducing the size of resources, a page can load faster and provide a better user experience.

Improving FCP is an essential part of page speed optimization, and there are numerous ways to go about it. By understanding how FCP works and what can be done to improve it, web developers can create faster, more responsive websites that provide a better user experience.

CLS

Cumulative Layout Shift (CLS) is a metric that measures how often users experience unexpected layout changes during page loading. This can be caused by things like images or ads that suddenly load in a different location than expected, resulting in a "layout shift" on the page. While a single layout shift may not seem like a big deal, it can have a major impact on the user experience if it happens frequently. Fortunately, there are a few ways to reduce CLS and improve page speed. One is to optimize images so that they load quickly and consistently. Another is to use "lazy loading" for images and other elements, which means loading them only when they're needed. By reducing CLS, you can improve the user experience on your website and encourage people to stick around longer.

FID

First Input Delay, or FID, is a metric that measures how long it takes for a page to become interactive. In other words, it's the time between when a user first interacts with a page (e.g., clicks a button) and when the page responds to that interaction. FID is an important metric because it directly impacts the user experience. A page with a long FID will feel slow and unresponsive, while a page with a short FID will feel snappy and responsive.

There are several ways to improve FID. One is to optimize the page's resources (e.g., reduce the size of images and JavaScript files). Another is to defer non-essential JavaScript so that it doesn't block the page from becoming interactive. And finally, you can use proactive anticipating so that the page is already interactive by the time the user tries to interact with it. By doing these things, you can ensure that your page has a low FID and provides a great user experience.

INP

Page speed has been a ranking factor for desktop searches since 2010,  and is also a ranking factor for mobile searches. Despite this, many websites still have page speed issues. Interaction to next page (INP) is a page speed metric that measures how long it takes for a page to become fully interactive. The page is considered fully interactive when the page responds quickly to user input, such as clicks or key presses. Improving INP is essential for providing a good user experience, and can also help to improve your website's search engine rankings. There are a number of ways to improve INP, including optimizing images and using caching. By making a few simple changes, you can greatly improve your website's page speed and provide a better experience for your users.

TTFB

Time to First Byte, or TTFB, is the amount of time it takes for a browser to receive the first byte of data from a web server. page speed is one of the most important aspects of web development, as it can have a significant impact on user experience. A slow TTFB can lead to a number of problems, including increased page load times, decreased conversion rates, and lower search engine rankings. There are a number of ways to improve TTFB, including optimizing code, using caching techniques, and improving server performance. By taking these steps, you can help ensure that your website loads quickly and efficiently.
