What seo-authority-builder does

The subagent reviews content for experience, expertise, authority, and trust signals. It checks author credentials, source quality, first-hand examples, contact details, and other credibility indicators, then suggests concrete changes. Its description specifically calls out YMYL topics.

Possible deliverables include an E-E-A-T scorecard, author bio templates, a topical authority map, a citation strategy, and schema recommendations. It also examines topic coverage and internal links. The agent recommends changes; it does not claim to apply them to a site.

The configuration names sonnet as its model. For Claude Code, add the marketplace, install the plugin, and use .claude/agents/seo-authority-builder.md.
