The document discusses organizing keyword modifiers to develop a long tail keyword strategy. It defines thematic modifiers as additional words added to core keywords, such as terms related to the niche or geography. It then provides three methods for organizing these modifiers: 1) Grouping modifiers by general or niche categories. 2) Organizing modifiers in a tree structure with the core term as the trunk and modifiers as branches. 3) Structuring modifiers in a hierarchical table with increasing specificity at each level. The goal is to use keywords more effectively and optimize website structure and content.
