Abstract: A system configured to perform content comparison between product web pages, or “product pages”, on one or more web sites through which products (e.g., goods, services, and/or other products) are sold is presented. The system may be configured to generate comparison reports and recommendations based on similarity scores. The similarity scores and/or recommendations may reduce instances in which product pages for the same or related products are identified as duplicates by search. The similarity scores and/or recommendations may enhance the content quality, the visibility, and/or relevance of the product pages by keeping them substantially different.
