Unlike human readers, agents like Claude Code, Cursor, and Cline compress multi-page navigation into single HTTP requests, bypass all client-side analytics, and silently discard content that exceeds their context windows. Key AEO practices include: auditing robots.txt to allow AI agent traffic, adding an llms.txt sitemap for agent discovery, writing skill.md files that declaratively describe API capabilities, keeping documentation pages under token limits (15K–25K tokens for most pages), serving clean Markdown alongside HTML, surfacing token counts as metadata, adding 'Copy for AI' buttons, and creating AGENTS.md files in repositories. A companion open-source audit tool called agentic-seo automates checking for these signals. 112 7 [See all Addy Osmani archives](/sources/addy/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/addy/best-of/2026/04#page","url":"https://daily.dev/sources/addy/best-of/2026/04","name":"Best Addy Osmani Posts — April 2026","description":"The most upvoted Addy Osmani posts from April 2026, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/addy/best-of/2026/04#items","numberOfItems":1,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/agentic-engine-optimization-aeo--tp3ht3sjt","name":"Agentic Engine Optimization (AEO)"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"Addy Osmani","item":"https://daily.dev/sources/addy"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/addy/best-of"},{"@type":"ListItem","position":5,"name":"April 2026"}]}]} ```
