Google Tag Manager
But sometimes, a site can have so many tags, that it becomes cluttered and difficult to manage or even reduce the speed of your site. That’s where Google Tag Manager can help.
With Tag Manager, you no longer have to add tags manually to a website. Instead, you can use Tag Manager to create Analytics, AdWords, or any third-party tags, and specify when they should fire. This simplifies and speeds up the process of tag deployment, and can really streamline tag loading for faster website performance. It can also help you manage different versions of your tags, making you less reliant on developers for changes.
NUI can help you with a measurement plan and a tag management strategy. Data layers, along with variables and events, will be used to pass information from your website into other tools for marketing and analysis. Setting up advertising and remarketing tags can also be done in Tag Manager with the goal to collect data to better understand customer behavior. You can view detailed data in your Google Analytics.
