An example method includes receiving packets associated with network traffic and identifying location information associated with an end user related to the network traffic. The method also includes extracting keywords from the network traffic, the keywords and the location information are used as a basis for rendering an advertisement on digital signage that is physically proximate to a current location of the end user. In other embodiments, the network traffic can be matched against access control lists, which are configured with Internet protocol (IP) addresses relating to search engines. Additionally, the network traffic can be classified based on fields in the packets, wherein the fields include a source Internet protocol (IP) address, a destination IP address, and a transmission control protocol (TCP) port. In more particular embodiments, the network traffic is hypertext transfer protocol (HTTP) requests originating from a handheld device operated by the end user.
