This document summarizes Daniel Avidor's presentation on viral marketing and Redmatch's approach. Redmatch uses viral marketing techniques to rapidly spread job listings. Like viruses, it takes advantage of social networks to exponentially multiply messages. Redmatch also localizes to different languages and markets, scales to large databases and traffic, and integrates with other systems. Its matching engine anonymously and interactively matches candidates to jobs in real time based on skills and requirements. This helps spread job listings virally through social sharing and networks.
