This document summarizes four case studies about scaling content through cross-collaboration at different organizations. The first case study describes optimizing product pages by manually adding cross-links between related pages, which led to increases in traffic, conversions, and rankings. The second case study involved consulting with a company's video team to optimize existing videos. The third case studied integrated an SEO team into a new CMS development project. The final case study described an SEO team providing recommendations for a new page concept at a client's request.
