Data can be communicated in different formats via different sources. The data layer represents the promise of omnichannel marketing that many digital marketers strive to achieve. In the Data Layer Variable Name field, enter the key exactly as it was written in the code, e.g. The ability to access commands and methods of objects stored in dataLayer, and the possibility of running custom functions in the context of the data model. It also synchronizes the information which is to be transmitted over the data. If a push occurs, the variables in the push are evaluated. A governance model, in this context, is a document (or documentation) which describes as clearly as possible the Data Layer, its parts, the business domains it’s deployed in, its various owners, its version history, its variables, how risk management is handled, etc. There has to be a mutual understanding that the shape of the layer becomes clearer with time. Thus, documentation and version control is left up to the sophistication of the tool itself. In this article, I will consider Data Layer to comprise the following definitions: The description of business requirements and goals, aligned in a format that is readily transferrable to technical specifications, The concept of a discrete layer of semantic information, stored in a digital context. It’s very much a technical concept, since its existence is justified by the limitations imposed by certain web technologies (JavaScript, for example) upon how browsers interact with applications (Google Tag Manager, for example). These cookies do not store any personal information. Writing this article is dangerous. But opting out of some of these cookies may affect your browsing experience. Similarly to any aspect of digital analytics, a Data Layer should also be treated as something that’s constantly in flux. These are all transparent to Google Tag Manager’s users, of course, but they explain why, for example, the Data Layer Variable Macro can access dotted variable names (gtm.element) and properties (gtm.element.id) equally, and also why you can push multiple values with the same key into dataLayer but only the most recently pushed value is available for tags which fire after the push. Coming up with one for a data structure which is at the mercy of a number of different parties, all with varying levels of expertise (and general interest), is even more difficult. Product: AudienceStream Customer Data Platform, TiQ Tag Management. As data goes down through the stack, it is broken up into packets, and certain layers add headers and footers to each packet – for example, at layer 3, an IP header containing the destination and source IP addresses is added to each packet. Here we are using a reverse IP address lookup service to reveal a visitor’s industry. It is mandatory to procure user consent prior to running these cookies on your website. The most common approach, I believe, is that the business requirements and goals are translated into a set of key-value pairs, which must be rendered / deployed by server-side code, so that dataLayer is populated with all the necessary data before the GTM container snippet loads. To visualize or present layer data in multiple ways, you can create a copy of a layer. If you train a series network with the layer and Name is set to '', then the software automatically assigns a name to the layer at training time. For a web store, for example, business requirements and goals might include transactional information (what was purchased), user data (who made the purchase), spatial and temporal details (where was the purchase made in and at what time), and information about possible micro conversions (did the user subscribe to product updates).
