Live Tag

The Quantcast Live Tag is a universal tracking pixel that can be easily installed on your website. Once installed, you can define and track various site events, view site activity for the past seven days, and retrieve codes required to track activity on your website.

Accessing the Live Tag Events

In the Quantcast Platform, use the navigation menu on the top left of the screen, then select Event Manager under Assets.

Your Event page will look similar to this:

Live Tag Buttons

On the Event page, there are three buttons, dependent on whether you have implemented the Live Tag: Add Conversion Event, Tag Inspector, and Install the Live Tag if you have not yet installed the Live Tag, and Add Conversion Event, Tag Inspector, and Edit Connection if you have installed the Live Tag.

Buttons for adding conversion events and installing Q Pixel on a web interface.

Buttons for adding conversion events, inspecting tags, and editing connections are displayed.

Add Conversion Event: Create data-passback and URL-based events for activities on your site. See the Track Events article for more information on URL-based and data-passback events.
Tag Inspector: Get the Chrome extension that can inspect your tag.
Install Live Tag/Edit Connection: This includes your base pixel and P-code. The base pixel tags all pages on your website, and the P-code is a unique identifier for your account. See Install Live Tag for a guide on installing your base pixel.

Site Tag Activity

The Site Tag Activity chart shows all activity observed on webpages with a pixel implemented and associated with your p-code. You can filter which events are displayed in the graph for the past 7 days.

Site Events

Tag Events are created within the platform through the Add Conversion Event and Install Live Tag.

List of site events with names, types, and active status indicators.

Live Tags

Live Tags consist of two snippets of JavaScript:

Base Tag is required to track any website activity
Data Pass-back Tag builds upon the base tag to measure specific actions and capture passed-back variables.

Base Tag

The Base Tag serves as the foundation for the Live Tag. It needs to be added to every page of your website to enable data passback tags and rule events to function and to build audience data from all traffic on your site.

Place the Base Tag in your website's <head> section so it appears on all pages you wish to track. Quantcast strongly recommends that all advertisers we work with install our pixel on their entire site, regardless of the campaign's nature, unless our Terms and Conditions permit otherwise. The more tag coverage a site has, the stronger your custom audience model will be and the easier it will be to leverage all Quantcast product offerings. You can also enable Enhanced Matching, which helps improve the quality and accuracy of the audiences you create on our platform.

If you are using a tag manager, please refer to the instructions for your tag manager, which are linked in this section.

If you use Google Analytics, the Quantcast Pixel will collect your Google Analytics ID, which gives you the option to integrate your Quantcast campaigns with your Google Analytics account.

Data Pass-back Tag

URL-Based Event

Once the base tag is installed, you can create URL-based events to track activity on your website. Rule events let you trigger events automatically based on URLs visited or user interactions with specific DOM elements.

For example, to observe visits to your website's homepage "www.website.com/homepage", you can create a rule. Name the rule-based event "Homepage", and use the condition "URL" contains "homepage". Once saved, the "Homepage" event will fire anytime "www.website.com/homepage" loads.

Select URL-based event type to create a conversion event without coding requirements.

URL Events are configured based on a URL or DOM conditions and can be added to any page as long as the base tag is implemented. For instructions on how to create rule-based events, click here.

Our tagging best practice article includes guidelines on recommended rule events.

You can verify if a label is firing correctly by using the Verify URL tool on the top right corner of the Event Manager page.

Data Pass-back Event

Data pass-back events are used for site events that require the pass-back of pre-specified variables, such as revenue, product category, or order ID. These events can also be used where an action cannot be tracked using a URL condition, such as a button click. An example would be tagging a "Purchase Now" button and passing back revenue and product category.

These events require additional code beyond the base tag. For more information on installing a data pass-back tag, read our article on Data Pass-back and Advanced Installation: Full Tag.
