Case Study: 6Sigma
Industry: Online education, process improvement
Delivery: Global, remote cohorts and self-paced
Goal: Win AI answer visibility for non‑branded course selection queries.
Outcome
6Sigma appears in the number three position in ChatGPT for the query “best six sigma online classes,” with strong coverage for adjacent prompts such as “best online six sigma certification,” “lean six sigma courses online,” and “green belt online course.” This puts the brand in front of high intent learners at the moment of decision.
The Challenge
Course providers look similar to AI systems. Assistants favor entities with clear credentials, consistent program names, and concise facts about outcomes, time to complete, and price. 6Sigma had quality programs, but assistants were not consistently selecting it for top recommendations.
