AI Agents

AI Agents are autonomous systems that use LLMs to perceive their environment, make decisions, and take actions to accomplish goals. They can use tools, run code, and execute multi-step workflows without human intervention.

Definition

AI agents extend beyond single-turn generation by maintaining goals, planning sequences of actions, and adapting based on outcomes. An agent can search the web, read pages, extract information, make decisions, and take actions toward an objective. Function calling enables agents to use tools like search engines, calculators, or APIs.

Agents represent a shift from passive AI systems that respond to queries to active systems that accomplish tasks. In AI search contexts, agents can dive deeper into topics, compare multiple sources, and synthesize more nuanced answers by actively researching rather than passively citing retrieved documents.

Why it matters for AI visibility

Agentic AI search systems actively research answers rather than passively retrieving sources, potentially looking across your entire website, checking claims against sources, and verifying information. Your brand's credibility becomes more important: agents validate claims and penalize sources that contradict other information.
