What Is SEO (Search Engine Optimization)
SEO (Search Engine Optimization) means improving a page's visibility and position in traditional search results. SEO and GEO share the crawl, structure, and internal linking foundation, but their evaluation standards differ: the former looks at position and clicks, the latter at citations and description.
Definition
This site's working definition: SEO is the work of improving how a page is indexed and retrieved in search results through crawlable structure, clear information architecture, page-level optimization, and content quality.
The main observation items are indexed page count, impressions, clicks, and average position. These figures come from search platform consoles, their standards shift as platforms change, and the collection date must be recorded.
Boundaries: what it is easily confused with
| Easily confused concept | Key difference |
|---|---|
| GEO | The goal is being cited in generative answers; position is not the measure |
| AEO | The goal is becoming a direct answer source; an answer format |
| Paid traffic | Paid media buys impressions; SEO relies on organic retrieval |
Common misconceptions
- Equating SEO with keyword stuffing. Stuffing hurts readability and does not improve extractability.
- Looking only at ranking, not page quality. A page that ranks well but whose conclusion depends on earlier text cannot be cited.
- Believing that finishing SEO means finishing GEO. The goals differ and must be verified separately.
Basis and verification
This definition is this site's working definition, marked L2. Statements about search platform mechanics describe only publicly observable phenomena as of the verification date, with no judgment about capabilities.
Review cycle: 180 days, moved earlier when platform documentation changes.
