About the Book
Claude Code is easy to start and hard to run well for months. This guide covers what we learned using it daily in a small business with an ERP, e-commerce sites and mobile apps. Inside: a three-layer memory protocol and why searching memory before searching the web matters (23% of web searches were near-duplicates of earlier ones); the real cost of loading a big index file and how to prune it; hooks that inject candidates into the prompt; how the auto-mode classifier behaves and why you should not work around it; when delegating to subagents helps and when it does not; verifying audit findings before accepting them; and a checklist. Written for solo developers, small-business owners who code and agencies adopting Claude Code. 12 pages, PDF.

About the Author
Leandro Salerno
Leandro Salerno leads marketing and technology at Austhen, a Brazilian industrial audio group with 20+ years of engineering, behind the brands Sansara, IBS and Xcene.
He didn't learn AEO from a course — he learned it shipping real sites: building and optimizing the group's B2B catalogs in Next.js and Firebase, and fighting every indexation and schema bug documented in this book. After getting those sites cited by ChatGPT and Perplexity, he packaged the method into AEO in Practice.
He writes for developers and agencies who want to master the next layer of search before the competition does.
