About the Book
Firebase fails quietly: the deploy says SUCCESS, the site opens, and the problem shows up days later as an email that never arrives, a login that hangs only on iPhone, or a fix that never took effect. This guide collects the pitfalls we hit in production across 13 real projects (ERP, e-commerce, mobile apps, B2B catalogs), each with the symptom, the cause, how to verify it and the fix. Inside: traffic stuck on an old Cloud Run revision; env vars that vanish on the next deploy; secrets saved with a trailing newline; Hosting cache that hides deploys for an hour; ignore rules that expose .git and dotfiles; CSP and the Safari-only Auth hang; Functions Gen2 out-of-memory errors that look like bugs; Firestore index deploys that delete indexes; a login gate that only checked one URL prefix; OneDrive breaking builds; CI traps and cost reporting traps. Written for developers and agencies who ship on Firebase. 10 pages, PDF, with a deploy checklist to print.

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.
