GEO Doesn't Work Without SEO — Sorting Out SEO, AEO and GEO

SEO, AEO and GEO, defined

As AI usage spreads, interest in GEO has grown faster than the vocabulary has settled. The distinctions:

• SEO (Search Engine Optimization): optimizing to appear on search engine results pages.
• AEO (Answer Engine Optimization): answer engine optimization. Google has stated there is no difference between AEO and SEO.
• GEO (Generative Engine Optimization): getting cited inside the answers generated by LLMs such as GPT, Gemini and Claude.

That leaves two things to actually manage: SEO and GEO. Some people use AEO to mean "AI engine optimization" — in that usage, AEO and GEO are the same thing.

How AI systems pick up your content

GPT, Gemini and Perplexity each run their own web search infrastructure rather than calling Google or Naver APIs. Their results, however, correlate strongly with what ranks on conventional search. Gemini especially: it is Google's model, so ranking well in Google Search raises the odds of being cited.

Technically, then, a site with technical SEO in place already has the foundation for GEO. If a vendor offers "GEO only," that is worth questioning. Without SEO underneath, GEO does not hold.

The two halves of SEO

Technical SEO — the dynamic sitemap is the usual gap

Technical SEO covers HTML meta tags, OG images, robots.txt and sitemaps. Without it, search engines cannot properly read the page no matter how good the writing is.

The most commonly missing piece is a dynamic sitemap. A sitemap generated once and left alone never includes new posts, and since crawlers work from the sitemap, new content goes undiscovered. The check is simple: request yourdomain.com/sitemap.xml, publish a new post, then request it again 5–10 minutes later and see whether the URL list updated.

Content SEO — no textbook for this half

Content SEO is measured by time on page, bounce rate and scroll depth. No amount of technical configuration produces those; the writing does. This is why the same tool and the same prompt yield very different results in different hands. AI is a complement, not a replacement — output quality still depends on someone who can write. Before starting an SEO program, confirm the marketer running it can actually write.

Where SEO and GEO differ

Three surface differences: the destination (a results page versus the body of an LLM answer), the input style (keyword queries like "MVP development cost" versus natural questions like "roughly how much does MVP development cost?"), and the engine itself. But GEO's priority is still to layer citation-friendly structure on top of an SEO foundation. For a blog, the two are nearly the same job.

Checking whether you get cited

The fastest method is to ask GPT, Perplexity and Gemini your article's core question and inspect the source links. Then monitor analytics for referral sources like chat.openai.com and perplexity.ai. GEO analytics tools such as Profound and Otterly.AI also exist.

Canonical tags for cross-posting

Publishing the same article on Medium and your own blog carries no penalty as long as the canonical is set correctly. If your blog is the original, put its URL in Medium's Canonical Link field under Advanced Settings.
