Third-Party Data
What is Third-Party Data?
Third-party data is information collected by an outside organization that has no direct relationship with the user and is then aggregated and sold for targeting. Once central to digital advertising, its use has declined sharply due to privacy regulations and the phase-out of third-party cookies.
Tokenization
What is Tokenization (in AI)?
In AI language models, tokenization is the process of breaking text into smaller units called tokens that the model can process. Understanding tokens helps marketers manage costs, prompt length, and output limits when using generative AI tools. (In payments and security, the term refers to a different concept—replacing sensitive data with a non-sensitive substitute.)
Topic Cluster
What is a Topic Cluster?
A topic cluster is a content strategy that groups a central pillar page with multiple related articles, all interlinked around a core subject. It builds topical authority that helps both search rankings and the likelihood of being cited by AI engines.
Transfer Learning
What is Transfer Learning?
Transfer learning is a machine learning technique where a model developed for one task is reused as the starting point for a related task. It lets marketers build accurate models faster and with less data by leveraging existing knowledge.
Transformer
What is a Transformer?
A transformer is a neural network architecture that processes data—especially language—by weighing the importance of different parts of the input through a mechanism called attention. It is the foundation of modern large language models and most generative AI used in marketing.
