# angeo.dev

> Magento 2 AEO (Answer Engine Optimization) agency and open-source module suite. We make Magento and Adobe Commerce stores readable, citable and purchasable by AI systems - ChatGPT, Gemini, Claude and Perplexity - through structured data, AI crawler policy, agentic commerce protocols (ACP, UCP, MCP) and free MIT-licensed Composer modules.

Run by Ievgenii Gryshkun, a full-stack Magento 2 engineer working with Magento since 2015, based in the Netherlands. Every module referenced here is free and open source; the paid work is audits and implementation. Guidance on this site is dated and re-verified, because AI crawler names, protocol versions and shopping surfaces change frequently.
