Q Pixel
The Quantcast Pixel is a universal tracking pixel that you can install easily on your website. It provides you the ability to 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 Q Pixel
In the Quantcast Platform, use the navigation menu on the top left of the screen, then select Q Pixel under Assets.
Your Q Pixel page will look similar to this:
Q Pixel Buttons
On the Q Pixel page, there are three buttons: Add Event, Grab Pixel Code, and Verify URL.
Add Event: Create data pass-back and rule-based events based on the activity occurring on your site. For more information on rule-based events or data pass-back events, see the Track Events article.
Grab Pixel Code: Your base pixel and p-code. The base pixel is used to tag all pages on your website. The P-code is a unique identifier for your account. See Install Q Pixel for a guide on how to install your base pixel.
Verify URL: Test if your site has been correctly tagged. If Q Pixel has been correctly implemented, it will show the status as "Active".
Pixel Activity
The Pixel Activity chart shows you all activity seen on webpages that have a pixel implemented and are associated to your p-code. You can filter which events will populate the graph for the past 7 days.
Pixel Events
Pixel Events are created within the platform through "Add Event" and "Grab Pixel Code".
The pixel events table shows the following information:
Event: The name of the event
Type: The type of event.: Rule-based or data pass-back
Status: The current status of the event: Active or inactive
Total Impressions: The total number of impressions for the event
Eye icon: The last 20 records of the event triggered
Triggered Date: The date and time the event triggered
Domain and Path: URL the event triggered on
Order ID: For Order ID data pass-back events
Revenue: For Revenue data pass-back events
To better understand your audience and events, read the article on Exploring Saved Audiences.

Technical Details
Speed: The Q Pixel is asynchronous; it loads in the background and should not slow down the load time of your page.
Reliability: Quantcast uses a globally distributed server infrastructure. Traffic is routed to the most appropriate server through the use of DNS and BGP techniques to achieve the lowest latency possible.
Trusted & Privacy-Safe: We do not sell your audience or share it with any other advertiser.
Security: Our Internet-facing systems are regularly updated and hardened against attack. We regularly employ outside penetration test companies to test the security of the infrastructure and use several security measures to restrict network and server access.
Committed to Consumer Transparency & Choice: Quantcast is a member of the Network Advertising Initiative (NAI) and participates in the Digital Advertising Alliance (DAA) Self-Regulatory Program.
Q Pixel Tags
Q Pixel consists of two snippets of JavaScript:
Base Tag, which is required to track any website activity
Data Pass-back Tag, which builds upon the base tag to measure specific actions and to capture passed-back variables.
Base Tag
The Base Tag is the foundation of the Q Pixel. It needs to be added to every page of your website for data pass-back tags and rule events to function, and to build audience data from all the traffic on your site.
Place the Base Tag into the <head> section of your website so that it is present 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 nature of the campaign, unless our Terms and Conditions do not permit the use of our pixel. The more tag coverage a site has, the stronger your custom audience model will be and the easier it becomes to leverage all Quantcast product offerings. You can also enable Enhanced Matching, which can help you improve the quality and accuracy of the audiences you create on our platform.

If you are using a tag manager, please reference the instructions for your tag manager linked in this section.
Data Pass-back Tag
Rule-Based Event
Once the base pixel is installed, you can create Rule-Based Events to track activity on your website. Rule events enable you to fire 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.
Rule Events are configured based on a URL or DOM conditions, and can be added to any page as long as the Q Pixel 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 Q Pixel page.
Data Pass-back Event
Data pass-back events are used for site events that require 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 use would be tagging a "Purchase Now" button and passing back revenue and product category.
These events require additional code on top of the base tag. For more information on installing a data pass-back tag, you can read our article on Data Pass-back and Advanced Installation: Full Tag.
