What is offline and online?

Hi Friend,
Online means that a computer, device, or a person is connected to a network, and usually this means the Internet. While off-line means the computer, device, or person is not connected to a network, cannot be reached, and cannot communicate with any other computer or device.

In terms of SEO online refers to anything that is over the world wide web, whereas offline is anything that is not in the world wide web.

When a computer or other device is not turned on or connected to other devices, it is said to be "offline." This is the opposite of being "online," when a device can readily communicate with other devices.
