Claim One:
1. A method comprising: providing a multi-layer model that comprises: an advertiser layer associated with advertisers that compensate syndicators to display advertisements; a syndicator layer associated with the syndicators that buy click traffic from aggregators for the advertisements; an aggregation layer associated with the aggregators that buy the click traffic from spammers to insulate the syndicators and the advertisers from being associated with spam content; a redirection layer associated with redirection domains used by the spammers to fetch the spam content after a doorway web page is clicked; and a doorway layer associated with doorway web pages that the spammers promote to top search result positions to attract the click traffic; identifying, based on an analysis of the multi-layer model, the aggregation layer as a bottleneck layer that uses at least one Internet Protocol (IP) block to funnel the advertisements and to associate the advertisements with the spam content; and performing, by one or more processors configured with executable instructions, one or more corrective actions that act on the bottleneck layer to protect web browsers from search spam.
