Building Multimodal Web Agents with the Agent Development Kit

Modern web automation is shifting from rigid scripts to intelligent, adaptable systems. By leveraging multimodal web agents, you can build applications that understand both visual layouts and textual data to navigate the web just like a human. This text-based course guides you from the fundamental concepts of agentic design to deploying a functional multimodal web agent using the Agent Development Kit (ADK). You will learn how to structure agent decisions, manage complex browser states, and extract structured data from dynamic websites. In this course, you will: Learn the foundational architecture of multimodal web agents and how they process text and visual inputs; Configure the Agent Development Kit (ADK) to establish stable browser environments for automation; Manage persistent browser states, cookies, and session data to navigate multi-step user flows; Apply prompt engineering principles to guide your agent through complex web layouts; Extract and structure dynamic web data into clean, usable formats; Implement error-handling patterns to recover from unexpected page changes. You will start with core definitions and the theory of web agent design before moving into practical implementation steps, code walkthroughs, and conceptual exercises. This course is designed for software developers, automation engineers, and tech enthusiasts who want to transition from traditional web scraping to intelligent agentic automation. No prior experience with web agents is required, though a basic familiarity with programming concepts is helpful. Start reading today to build your first intelligent web assistant.
