The invention discloses a method of evaluating the web page importance, which comprises the following steps: (a) generating link map which includes a plurality of the corresponding web page nodes and every link corresponding the every webpage; (b) achieving and recording the hitting operation of the node in the link map by the terminal; (c) proceeding iterative computation of the general important value of every node according to the hit record of the link map and node in the link map. The invention also discloses a system of evaluating the web page importance. The invention distributes the general important value of the father node to the general important value of every son node and makes the general important value of the web page more rational by counting the probability of forward link in the hitting web page when the terminal browses the web page.
