PillarCluster Topical Authority Builder

PillarCluster Topical Authority Builder automates the creation and scheduling of comprehensive SEO topical silos directly within WordPress.

Starting from a single root keyword and target URL, the engine recursively branches into sub-topics, generates technical supporting articles via AI, and automatically knits them together using multi-directional internal links (upward to parent pages and lateral mesh links across sibling topics).

Features:
* Automated 3x recursive branching architecture
* Configurable Cluster Depth Cap (Choose Tier 1 through Tier 5, or select Exponential mode)
* Customizable scheduling cadence (set intervals down to 5 minutes between posts)
* Precise internal linking (Upward parent links and Lateral mesh links across siblings)
* Excludes deep supporting sub-tier articles from the main blog loop
* Built-in per-cluster Drain Mode to halt recursive branching cleanly
* Complete cluster status detection (Active, Draining, and Completed) with safe archiving
* Cluster Deletion tool to wipe an entire cluster and unschedule pending posts
* Supports Google Gemini API and OpenAI-compatible endpoints (OpenRouter, Groq, OpenAI)
