Why CMOs Must Rewire SEO Thinking for the AI Search Era
The marketing landscape is being rewritten—literally—by artificial intelligence. For CMOs, Heads of Growth, and SEO leads, the old rules of search no longer apply in isolation. Generative AI tools like ChatGPT, Claude, and Google’s SGE (Search Generative Experience) are now determining what content gets cited, surfaced, or directly answered.
This article introduces three critical frameworks AIO, GEO, and AEO designed to optimize your content for today’s AI-driven search reality. Each model addresses a different layer of content visibility:
AIO: Make content understandable and machine-readable by AI systems.
GEO: Increase chances your content is cited by generative AI tools.
AEO: Win direct answer boxes, voice search, and featured snippets.
You’ll learn not only what these mean, but also how to structure your content strategy around them for maximum ROI and long-term authority.

Format data using tables, bullet lists, and short paragraphs
Implement schema.org structured data for articles, FAQs, and reviews
Ensure mobile-first formatting and accessibility
What Is GEO (Generative Engine Optimization)?
Focus:

Goals:
Become a preferred source for AI answers
