What Is GEO? Generative Engine Optimization Explained

When a large language model answers a question and cites a source, it made a choice. Out of everything it could have pulled from, it picked one page over the rest. Generative Engine Optimization, or GEO, is the practice of making your content the one that gets picked.

How LLMs actually decide what to cite

Generative engines aren't reading your page the way a search algorithm counts keywords. They're evaluating whether a passage looks credible and easy to extract cleanly. Three factors carry real weight:

• Author and source credibility signals. Author schema markup, a visible byline, or rel="author" attribution all tell a generative engine that a real, identifiable source stands behind the claim, which matters a lot when the engine is deciding whose version of a fact to trust.
• Data and statistics. A specific number or percentage is more quotable than a vague claim. "Conversion rates improved 34%" is something an LLM can lift directly into an answer. "Conversion rates improved significantly" is not.
• Lists and tables. Structured, scannable formatting is dramatically easier for a model to parse and extract verbatim than a wall of unbroken paragraphs.

GEO versus AEO: related, not identical

AEO is about being structured well enough to be selected as a direct answer, mostly by answer-box style features like Google's AI Overviews. GEO is about being credible and extractable enough to be cited by a generative model synthesizing a longer response, like ChatGPT or Perplexity. A page can score well on one and poorly on the other. Most sites need both.

Why this is worth fixing now

Once a generative engine settles on a source for a given question, that source can end up cited across millions of conversations without ever sending a single visitor a link to click. Being the cited source is a new kind of visibility, and right now, most sites haven't structured anything specifically to earn it.
