# Fili Wiese
Technical SEO consultant and ex-Google engineer fixing search penalties.

## About

Fili Wiese untangles the technical side of search engine optimization. Before starting his consultancy Search Brothers, he worked as a senior technical lead on Google's Search Quality team. Today, he audits sites, trains developers, and helps websites recover from search penalties.

He focuses on helping teams control exactly how bots interact with their content. His talks break down essential developer skills—from mastering the strict syntax of robots.txt to block AI scrapers, to properly implementing HREFLANG tags for global search visibility.
