White label SEO is an outsourcing business model that works when a digital agency hands over its client’s SEO tasks to a specialized third-party service provider who performs the actual work, but the agency then rebrands these services and delivers them to the client under its own name and branding. The white label agency handles the “behind-the-scenes” work, such as keyword research, link building, and content creation, while the partner agency focuses on client relationships and strategy.
