Breadth
Include the distinct support areas the search task genuinely requires.
Definition and diagnostic
Semantic coverage is the breadth and depth of relevant entities, concepts, attributes, questions, and relationships that help a page explain its main topic clearly and completely.
A page can repeat the target phrase and still fail to explain the topic. Strong coverage surrounds the main entity with the support the reader expects next. The support must remain close enough to the page purpose to deepen the answer rather than widen the asset into a loose catch all resource.
Core model
Keyword coverage checks whether phrases appear. Semantic coverage checks whether the page explains the topic through the right meanings, support concepts, attributes, relationships, and answer structure.
Include the distinct support areas the search task genuinely requires.
Explain the attributes and relationships that change understanding or action.
Place supporting concepts near the entity or section they clarify.
Move overflow ideas into sibling pages when the page job changes.
Five review signals
The main query receives a direct and complete response.
Nearby ideas explain how the topic works and what it connects to.
The main entity is described through properties that matter to the user.
The asset includes the comparison, process, proof, or next step the query expects.
Sibling pages and internal links carry depth that should not sit on the main asset.
Internal MIRENA workflow
MIRENA maps coverage from entities, intent, result set expectations, information gaps, and page boundaries.
MIRENA states the exact topic, query task, and page role.
Entity, query, result set, and source evidence reveal the concepts the answer needs.
Named concepts are checked for attributes and connections that remain unexplained.
MIRENA separates page level support from ideas that belong on sibling pages.
The final structure is checked for thin areas, repeated sections, and drift.
Practical example
A page explains featured snippets.
The asset defines paragraph, list, and table snippets but omits query intent, section structure, answer formatting, rewrite decisions, and common failures.
The asset keeps the definition, adds the support needed to apply it, and links deeper technical or workflow topics into separate pages.
Failure modes
Counting phrases instead of checking the semantic neighborhood.
Adding related terms without explaining their function.
Covering every adjacent topic at equal depth.
Copying the common result set without a better relationship or example.
