Abstract: The systems and methods described herein provide manufacturer-linked landing pages for online advertising. A retailer may sell products manufactured by a number of different manufacturers. A manufacturer may pay the retailer to advertise products they manufacture. The retailer may advertise itself or products or product types it sells online. On responding to such advertisements, a user may be first directed to a landing page. The landing page may be the primary web page of the retailer, or a web page containing some subset of products or product types that the retailer sells. A landing page for the retailer may simultaneously display products from different manufacturers. If a particular manufacturer has paid for some portion of the advertising for that retailer, it may be desirable from the perspective of the manufacturer for advertisements to lead to landing pages that only display products that they manufacture, and exclude products from other manufacturers.
