# Scope3 > Scope3 is the infrastructure layer for agentic advertising — where buyer agents meet seller agents to plan, buy, optimize, and report on advertising campaigns across all media channels through natural language instructions. ## About Scope3 provides the marketplace and protocol infrastructure for AI-powered advertising. Brands describe campaign goals in plain language, and AI agents handle targeting, bidding, optimization, and reporting across programmatic, social, CTV, retail media, podcasts, and OOH. The Advertising Context Protocol (AdCP) is the open standard that makes this possible — defining how buyer and seller agents discover each other, negotiate terms, and transact. ## Core Pages - [Home](https://scope3.com/) - [Agentic Advertising (pillar)](https://scope3.com/agentic-advertising) - [Advertising Context Protocol (AdCP)](https://scope3.com/agentic-advertising/adcp) - [Brand Platform](https://scope3.com/agentic-advertising/brands) - [Storefronts](https://scope3.com/agentic-advertising/storefronts) - [Pricing](https://scope3.com/agentic-advertising/pricing) - [Governance](https://scope3.com/agentic-advertising/governance) - [Get started](https://scope3.com/agentic-advertising/get-started) ## Glossary - [Agentic Advertising](https://scope3.com/agentic-advertising/glossary/agentic-advertising): The use of AI agents to plan, buy, optimize, and report on advertising campaigns across all media channels through natural language instructions. - [Advertising Context Protocol (AdCP)](https://scope3.com/agentic-advertising/glossary/advertising-context-protocol): An open standard for agent-to-agent communication in advertising, enabling buyer agents and seller agents to discover, negotiate, and transact media. - [Agent-to-Agent Communication](https://scope3.com/agentic-advertising/glossary/agent-to-agent-communication): The standardized exchange of structured messages between buyer agents and seller agents to negotiate and execute media transactions. - [Brand Agent](https://scope3.com/agentic-advertising/glossary/brand-agent): An AI agent configured with a specific brand's standards, audiences, and campaign objectives that autonomously manages advertising on behalf of that brand. - [Seller Agent](https://scope3.com/agentic-advertising/glossary/seller-agent): An AI agent that represents a publisher or media owner, managing inventory availability, pricing, and deal negotiation. - [Brand Standards](https://scope3.com/agentic-advertising/glossary/brand-standards): Governance rules that define placement restrictions, audience guardrails, and budget limits that every agent must follow when executing campaigns. - [Discovery Protocol](https://scope3.com/agentic-advertising/glossary/discovery-protocol): The mechanism by which buyer agents find and evaluate available inventory from seller agents across the open marketplace. - [MCP Integration](https://scope3.com/agentic-advertising/glossary/mcp-integration): The use of the Model Context Protocol to connect Scope3's agentic advertising capabilities directly into AI assistants like ChatGPT, Claude, and Copilot. - [Media Portfolio](https://scope3.com/agentic-advertising/glossary/media-portfolio): A diversified mix of inventory across publishers and channels, assembled by an agent to achieve specific campaign outcomes. - [Natural Language Campaign](https://scope3.com/agentic-advertising/glossary/natural-language-campaign): An advertising campaign configured and managed through conversational instructions rather than manual platform operations. - [Strategic Allocation](https://scope3.com/agentic-advertising/glossary/strategic-allocation): A media buying approach where AI agents distribute budgets across diversified media portfolios based on outcomes, not impression-level bidding. ## Blog - [What Is Agent-to-Agent Media Buying?](https://scope3.com/blog/agent-to-agent-media-buying): AI agents replace traditional channel-by-channel buying with portfolio-based coordination. - [Why AdCP Matters](https://scope3.com/blog/why-adcp-matters): The Ad Context Protocol enables AI agents to communicate and transact across the advertising ecosystem. - [The New Frontier for Customer Attention](https://scope3.com/blog/new-frontier-customer-attention): AI is creating new advertising surfaces within conversational experiences. - [Balancing Performance and Brand Suitability on Meta Campaigns](https://scope3.com/blog/brand-suitability-meta): How to achieve comprehensive brand safety on Meta platforms while maintaining reach and efficiency. - [Building the Future: Scope3 Elevates Engineering and Product Leadership](https://scope3.com/blog/engineering-product-leadership): Emma Mulitz promoted to Head of Engineering and Lillie Ratliff to Head of Product. ## Optional - [Full content version of this file](https://scope3.com/llms-full.txt) - [Blog listing](https://scope3.com/blog) - [Glossary index](https://scope3.com/agentic-advertising/glossary)
