What is Entity Density?
How thoroughly a page names the entities its topic requires. Missing entities competitors cover is a concrete, fixable gap; padding with repetitions is not coverage.

TF-IDF
Term frequency–inverse document frequency: how distinctive a word is to a document versus the corpus. A diagnostic for under-covered subtopics, not a formula for stuffing winning terms.
Entity Optimization
Writing so engines resolve which real-world things (people, products, places) a page is about: consistent names, disambiguating context, sameAs links, and schema. Entities are how modern retrieval thinks.
Content Gap Analysis
Comparing your topic coverage against competitors and unanswered audience questions to find missing subtopics. Gaps become briefs; briefs become clusters.
Keyword Research
Finding the queries your audience actually types and mapping them to pages worth building. Teams that always do it report strong content results far more often than teams that skip it.
Informational Intent
Queries seeking to learn: guides, definitions, how-tos. Serve with complete explanations, examples, and next-step links rather than sales copy.
Transactional Intent
Queries ready to act: buy, sign up, download. Serve with product fit, proof, pricing clarity, and one primary call to action.
