What is LCP (Largest Contentful Paint)?

LCP (Largest Contentful Paint) is a metric that measures how long it takes for the largest and most important visual element on the screen to load.

#What exactly counts as "content":

• a large heading,
• an image,
• a background image,
• a video preview.

Whatever the user sees first and orients themselves by.

#Why it matters:

If this element appears too late, the page feels empty or "sluggish". Even if everything already works, the impression of a slow site remains.

#Good scores:

• up to 2.5 seconds - fine;
• 2.6-4 seconds - needs improvement;
• more than 4 seconds - bad for SEO and UX.

In short: LCP is a measure of how fast a site "comes alive" for the eye.
