- +Early and credible on AI-search optimization with model-agnostic routing across GPT and Claude
- +Botsonic's action-taking support agents are legitimately agentic within guardrails
- -Agentic SEO oversells autonomy: the autonomous publish step is documented as coming soon, fixes need per-fix approval, and the best automation is enterprise-gated
