What is the difference between SEO, AEO, GEO and AIO?
Four acronyms, one goal: being the answer. Here is what each one actually means, who it is aimed at, and which one an education institute should fix first.
SEO makes you rank on Google. AEO makes the displayed answer come from your page. GEO makes AI assistants such as ChatGPT, Gemini and Perplexity cite you. AIO covers AI overviews and being correctly known by AI at all. They overlap heavily, share the same foundations, and should be run as one programme.
What this actually means for your institute
The one line version
- SEO: can they find and understand you.
- AEO: do they show your text as the answer.
- GEO: do other trusted sources make you worth quoting.
- AIO: does AI know you exist, and is what it knows correct.
Which to fix first, for an institute
- First, technical SEO and correct facts. Nothing works underneath a broken base.
- Second, AEO on your top twenty parent questions. This is the cheapest win, because you already have the demand and only the format is wrong.
- Third, GEO, because it takes the longest. Start reviews and video in month one even though the result appears in month four.
- AIO runs throughout. Making you readable and correct is day one work.

Do we need all four?
You need the foundations of all four, but not in equal weight. Most institutes get the fastest movement from AEO on existing demand, and the most durable advantage from GEO.
Is GEO just SEO with a new name?
They share foundations, but the levers differ. SEO rewards a well built page. GEO rewards specific, dated, self contained facts that other independent sources repeat, and it actively discounts self praise.
