We recommend Chrome for testing, but you can use any browser in a similar way.

  • Load any article page on the site.
  • Open Chrome DevTools (F12)
  • Choose Network tab
  • Enter p? or a? in the search box to filter all requests on the page


The tracker triggers two types of requests:
1. p request

The firstp request triggers a Pageview.
The second p request triggers after 10 seconds and it gives Article Read.


2. a request

One a request is triggered on every 5 seconds if there was any user activity on the article page (cursor move, click, scroll etc) and it tracks Attention Time.
This means that if a user chooses another tab in a browser or just leaves to do something else, attention time will not be measured until they come back and perform another reading activity.


Click on any of fired requests and look for the Query String Parameters at the bottom of the Headers tab.
Another option is to just type _ain in the DevTools Console tab and hit Enter. You will see how the _ain object is filled.
