The invention discloses an advertisement putting method in a real-time bidding system. According to the method, an advertiser website issues a httpRequest to a dsp system; the dsp system determines whether an identifiable self cookie identifier exists; if not, a newly-generated cookie is written into a current user browser, a return step to a redirection iframe is carried out, and commodity page information that is accessed currently by the cookie is recorded; returning to the redirection iframe and the dsp identifier cookie is carried out; the browser sends a current dsp cookie to a cookie service in an adx system; cookiemapping of the adx system checks whether a cooking identifier of the cookiemapping exists; if not, a newly-generated cooking is written into a current user browser, a current mapping relation of the adx cookie and the dsp cookie is bounded, and the cookiemapping service is written into multiple adx serves; and the cookie of the adx identifier is written back to the user browser. According to the invention, the flow is simple. The adx carries out maintenance on the mapping of the adx itself, receives the advertisement request, converts the request and sends the converted request to the dspcookie, and then sends the information to the dsp. Therefore, a multi-times interaction problem of the dsp is solved; and an advertisement can be putted to a user interested in the advertisement conveniently.
