First Meaningful Paint (FMP) is a performance metric that measures the time it takes for the primary content of a web page to become visible to the user. Unlike FCP, which tracks the first appearance of any content, FMP focuses on the content that is meaningful to the user, such as the main text or images.

Optimizing FMP is essential for enhancing user engagement, as it reflects how quickly users can access the core information they seek. Techniques to improve FMP include optimizing critical rendering paths and deferring non-essential scripts.
