What is website speed?
Website speed refers to the time it takes for a page to fully load all of its features and become accessible to the user. Faster websites tend to generate better results than slow websites.
It is important to differentiate site speed from page speed because, although both metrics are relevant, there are some differences:
Site speed: Average performance of a website's pages, indicating how it behaves in general for the visitor.
Page speed: Refers to the loading time of a specific page on the website.
Why is it important to measure website speed?

Consider that visiting your website may be the first time a user has come into contact with your brand. Making a good impression is key. Users aren’t willing to wait long for pages to load — seconds can make all the difference .
Slow websites can cause frustration, increase bounce rates, and can result in financial losses. Here’s how website speed can impact your business’ bottom line:
Conversion rates: Website speed directly impacts conversion rates, as when pages respond quickly, users are more likely to perform CTA actions.
User retention: A website with good speed keeps users for longer, due to agile and pleasant navigation.
User Experience (UX): A website that responds quickly to clicks and loads pages efficiently provides an excellent user experience, minimizing frustration.

Understanding Website Speed Metrics
There are several metrics that measure different aspects of site speed. Understanding each of them is important to correctly interpret performance reports and know exactly where to take action to adjust.
LCP (Largest Contentful Paint)
Measures the time it takes for the largest element on a page to load. LCP considers everything that appears in the first fold of the website, that is, without the user having to scroll down the page. The largest element can be an image, text, video thumbnail, list or any item essential for the user to be able to see the page.
To ensure a good experience, LCP should be below 2.5 seconds . Values above 4 seconds are considered bad and can degrade the user experience.
FCP ( First Contentful Paint )
Measures the time perceived by the user between the beginning of the page loading and the moment they can see something on the screen. It is a particularly relevant metric in user experience because a fast FCP helps the user understand that the site is responsive.
Google considers a FCP score to be good when it is below 1.8 seconds . Scores above 3 seconds are classified as poor.
FID (First Input Delay)
This metric measures the time between a user's first interaction with a page and the browser's response. Unlike FCP, which measures user perception of load time, FID measures a website's ability to react quickly to user interactions.
A good FID score should be less than 100 milliseconds . Anything above 300 milliseconds degrades the experience, which directly impacts site speed.
