Abstract: A method for annotating a target web page is performed at a server by: receiving an annotation obtaining request from a first terminal associated with a first member of an online chat group; identifying a first web page annotation and a first annotation position of the first web page annotation in a target web page; returning the first web page annotation and the first annotation position to the first terminal; receiving, from the first terminal, a second web page annotation and a second annotation position of the second web page annotation in the target web page; and forwarding the first and second web page annotations and the first and second annotation positions to a second terminal for display on the target web page at the second terminal in response to receiving a second annotation obtaining request from the second terminal.
