Implementing the asynchronous (i.e., it won’t slow down your site) Quantcast Measure tag gives you a deep view into who is visiting your site and what matters to them most.
With your tag in place, you’ll be able to see how many visitors you’re getting, what parts of the country (or world) they live in, detailed demographics about them, what kinds of products and brands they like and what TV shows they watch.
Note:
If you’re going to implement your tag manually, follow these steps:
Sign up for a free Quantcast Measure account. If you’ve already done that, you can ignore this step.
When you sign up for a Quantcast Measure account, we’ll immediately send you an email with a link to verify your email address. If you don’t see the email in your inbox, be sure to check your spam folder.
Click the email verification link, and you’ll be taken to a screen that asks you to enter the URL of the website you want to measure (see the example below).
Note: If you have Google Tag Manager on your site, go here for tag implementation instructions.

After you submit the site you want to measure, you’ll be taken to a screen that provides your Quantcast Measure tag (see example below).

This snippet of code is what will allow you to gather data about your audience, so you’ll want to select and copy it immediately. It may be a good idea to paste it into a separate document and save it in case you have to get up from the computer or close your browser.
Once you have your tag, place it within the footer HTML of the site you want to measure to ensure it fires on every page. The footer is marked by <footer> and </footer> tags. See an example below:

Make sure not to alter your tag, as that may prevent it from working properly.
After you’ve implemented your tag, Quantcast Measure will email you to verify that it is working properly.
Note: It takes 1-2 days for your audience data to become available, and it can take up to a week for deeper audience insights to appear. If you choose to create a (web-based) property in your profile to organize network insights, please ensure your tag is applied to the related site within 100 hours of property creation. Failure to do so will result in a permanent TAG NOT FOUND. To remedy this, delete and recreate the property. Otherwise, please contact our support team.
