In this episode a Google research paper is focused that examines how AI models for distinguishing human-written and machine-generated text can serve as unsupervised indicators of website quality. The study analyzed 500 million web pages and showed that such detectors can effectively identify low-quality pages, which are often characterized by machine-translated content, essay farms and SEO manipulation. The results suggest that search engines could use these findings to improve ranking systems and prioritize high-quality content, while potentially penalizing low-quality, AI-generated or heavily optimized pages. It is emphasized that the quality of the content is crucial and not the mere use of AI in its creation.

The podcast explains the importance of Natural Language Processing (NLP) for Google search. NLP enables Google to semantically understand search terms and content by recognizing entities and analyzing their relationships. This is the basis for the development of semantic search, where the meaning of words is considered in the context of the entire search term. Algorithms such as BERT and MUM use NLP to improve search quality and expand the knowledge graph. The transition from a classic, content-based index to an entity-based index is a key issue.
