SEO vs AEO vs GEO vs AIO: What Is Different and What You Need
Four acronyms, one foundation. Here is what each one targets and how to decide where to invest first.
The short answer
SEO earns rankings and clicks. AEO structures pages to be extracted as direct answers. GEO builds brand understanding and citations across AI assistants. AIO optimizes for Google's AI Overviews and AI Mode. All four rest on crawlable, trusted content, so most teams should run them together, starting with technical access.

What this means for your leadership team
Risk and revenue
For the CEO
You do not need four separate programs. The four disciplines share one foundation, so the question is sequence, not either-or.
Pipeline and reporting
For the CMO
Use the matrix to decide where effort goes first. Timeframes are typical ranges, not promises.
Delivery and governance
For the Head of Digital
Start with SEO and AEO if technical foundations have gaps. Add GEO and citations when you rank well but are not named in AI answers.
