Measurements : Are simply numbers whose purpose is to count or quantify given dimension values. For example, impressions, clicks, and conversions are data measurements. Dimensions : Are usually a textual description or characteristic of a given field. Examples include campaign name, site name, and creative type. Note that sometimes, dimensions can contain numbers. Since these aren’t for the purpose of quantification, but rather as a form of textual description, they’re still considered to be dimensions. For example, campaign ID may consist of a string of numbers, but only as a form of identification and not for the purpose of summation. Dimension Types a) Entity Dimensions – Entity Key, Entity Name, Entity Attribute. b) General Dimension – Date, Variable.
