Definition

Thin Mad-Libs PSEO fails because it adds no information gain. Each BatSignal industry page includes vertical-specific pains, pages, and competitor notes.

In practice

  • Pair definitions with crawlable HTML, metadata, and intentional robots policy
  • Measure outcomes (mentions, citations, pillar scores) after you change signals
