Reference

SEO terms, in plain language.

Use these definitions to ask clearer questions about a proposal or report.

SEO
Search engine optimization: work that helps search engines understand content and people discover and evaluate it.
AEO
Answer engine optimization: a term used for organizing content around questions and answers. It is not a promise that an answer service will include the page.
Query
The words a person enters into a search service. The same words can express different intentions in different contexts.
Search intent
The purpose behind a query, such as learning, comparing or finding a specific service. It is an interpretation that should be checked against the reader’s needs.
Crawling
A search system fetching content it has discovered. A successful fetch does not by itself establish indexing or a ranking.
Indexing
A search system processing content for possible inclusion in its results. Inclusion and display remain separate questions.
Canonical URL
A declared preferred URL for substantially equivalent content. It should agree with the actual content and URL plan; it is not a redirect.
Redirect
An HTTP or browser behavior that sends a request to another URL. A proposed redirect map is not evidence that a redirect has been applied.
404 response
An HTTP response indicating that the requested resource was not found. A page that says “not found” while returning success needs a separate review.
Title element
The HTML page title. It should describe the page clearly; search services may display a different title link.
Meta description
An HTML summary of a page. It should be accurate and useful; a search service may choose different snippet text.
H1
A primary page heading that identifies the main subject for a reader. A clear heading structure supports understandable content.
Internal link
A link between pages of the same website. Its label should help a reader understand the destination.
Sitemap
A list of website URLs, often supplied as XML to help discovery. Listing a URL does not prove that it is indexed.
Noindex
An indexing instruction used to keep a page out of search results when the instruction can be processed. It is not authentication or protection for private information.
Structured data
Machine-readable descriptions of information. Valid syntax does not establish that the described business fact is true.
Local citation
A published reference to a business and its details. Its usefulness depends on accuracy and context, not merely its existence.
Backlink
A link from another website. A link is not, on its own, proof of partnership, endorsement or a business relationship.
Impression
An appearance counted by a particular reporting source. Always check that source’s definition and date range.
Click
A recorded selection of a link or control. It does not automatically establish a visit, request or sale.
Conversion
A deliberately defined action in a measurement plan. The name alone does not tell you whether a durable inquiry or purchase occurred.
Attribution
A method of assigning credit for an observed outcome. Different methods and missing data can change the interpretation.
LCP
Largest Contentful Paint, a loading-performance measure. Keep the test conditions with the result.
INP
Interaction to Next Paint, a responsiveness measure. A page’s response to interaction matters beyond its first load.
CLS
Cumulative Layout Shift, a visual-stability measure. Unexpected movement can make a page harder to use.
Lab data
Measurements collected in a controlled test. Useful for diagnosis, but different from evidence gathered from real visitors.
Field data
Measurements from real use, subject to the source’s collection rules and available sample. An absence of data is not a zero.
Durable receipt
A persisted record proving that a request was accepted. A success screen or sent notification alone is not sufficient evidence.
Idempotency
Handling a repeated operation so retries do not create unintended duplicates. Intake should define how a repeated request is recognized.
Contribution
Revenue minus the direct costs included in a stated model. A contribution estimate is different from revenue or accounting profit.
