This document discusses marketing strategies for traditional products versus web services. For web services, it emphasizes that segmentation should target as many users as possible. The key aspects of the marketing mix (product, price, place, promotion) focus on building a strong user network to drive traffic and engagement. Rather than extensive planning, web service marketing should start small with a focus on continual improvement and expansion of the user network through an easy initial user experience. While some markets are saturated, new large opportunities continue to emerge online in areas like lending, real estate, entertainment and media.
