Concepts — category index
The concepts index gathers every definition article behind the terms used across provider and ranking pages. Coverage runs from placement tactics and link attributes through authority metrics to search-engine policy documents.
Listing scope
Each row carries the article title with its short description, both drawn from the article front matter. Rows render alphabetically by title, keeping reference lookup stable between scoring rounds and redesigns.
Column derivations
The index carries no scores, since concept articles explain language rather than grading providers. Articles cite public primary sources with access dates, and volatile statements carry month-level dating throughout. Providers appear only generically in concept articles, since named assessment belongs in provider coverage. New definitions join the index as tactics evolve, each reviewed against primary sources before publication. Corrections to definitions follow the same public route as other articles, with dated revision entries.
Use of the index
Readers open link building first, then follow shared terms into rankings and provider articles. Grading references point to the methodology page, which alone states the scoring constants exactly.
