First Contentful Paint (FCP) is a metric that measures when the users performs any action(click) on th web page such as clicking on the menu & how quickly it loaded for the user. A good FCP score is one that is as low as possible, ideally under 1 second.
However, it’s important to note that the target for FCP will depend on the type of website and the user’s expectations. For example, an e-commerce site may aim for a FCP of less than 2 seconds, while a news site may aim for a FCP of less than 1 second.
Keep in mind that a low FCP is important because it can have a big impact on user engagement and conversion rates. Users are more likely to stay on a website and complete a task if the website loads quickly.
