Nicolas Sacotte

Founder of Tasketeer

Nicolas Sacotte is founder of Tasketeer and has worked in search engine optimisation since 1998. He started during his business studies by building and optimising his own websites. Since 2012 he has run the SEO and content marketing agency ContentKing.de and advises companies in the DACH region, including TARGOBANK, comdirect, Interhyp, O2, SIXT, BURDA and sevDesk.

Tasketeer grew out of this agency practice: SEO rarely fails for lack of analysis, but because insights never become tasks with owners and deadlines.

Alongside client work, Nicolas builds and runs his own platforms, including visicheck.ai, womosuche.de, Zoom.Reviews and motorrad.news. There he implements what he writes about. His focus today is GEO (Generative Engine Optimization): how content becomes visible in ChatGPT, Perplexity and Google’s AI answers, how AI crawlers can be steered deliberately, and what structured data and grounding pages contribute.

He shares his knowledge in workshops, as a speaker and author at CAMPIXX, and in specialist articles on contentking.de. He also developed the SEO and GEO training in Tasketeer.
