Entity Variables (EAV) form part of the Entity-Attribute-Variable (EAV) model, which is a key concept in semantic keyword research and programmatic SEO projects. In this model, an entity is defined by its attributes, and each attribute, in turn, has different variables. For example, the entity ‘Influencer’ might have the attribute ‘Location,’ and the corresponding variables could include specific locations such as London, Paris, or Barcelona.
Implementing the EAV model involves several steps within programmatic SEO projects, often starting with keyword data validation to check for entities. The next stage is identifying the entity attributes and entity relationships to create a map of related entities and their attributes. For each identified entity attribute, a list of different variables is created.
The ultimate goal is to create different E-A-V combinations for each entity mapped out, resulting in a detailed structure for programmatic SEO keyword projects. These variables can be finite (like ‘Marital Status’: Single, Married, Married with Kids) or potentially infinite (like a ‘Name’: Anna Smith, John Johnson). The process of incorporating information about entity attributes and variables helps address content gaps and expand topic maps.
