Verification Pixel

#Why

The Knotch Verification Pixel provides an independent view of a publisher’s overall traffic, and collects data regarding page views, unique visitors, and basic browser metrics to incorporate into reporting results. Our pixel integration also triggers our third-party demographic provider so we can better understand your audience demographics.

As a component of Knotch Blueprint, the Verification Pixel enables you to showcase your value and trustworthiness to brands, and glean stronger audience data insights.

#How to Become Verified

Each verified publisher is granted a unique kvpid, to embed the Verification Pixel onto a page. You can contact us at blueprint@knotch.com to get verified and receive your unique kvpid from Knotch.

#How to Use the Verification Pixel

The Knotch Verification Pixel <script> element can be embedded on one or multiple pages. Place the element within the page's <head> element or near the end of the <body> element. The <script> element must also include a data-kvpid HTML5 data attribute in order to properly function. See below for an example HTML page, where the Knotch Verification Pixel has been embedded at the end of the <body> element.

For example, consider the below HTML document. We can see how the <script> element is added at the end of the <body> element: 

<!DOCTYPE html>
<html>
  <head>
    <title>Example Publisher Page</title>

    <!-- Page assets included here... !-->
  </head>
  <body>
    <!-- Normal page content here... !-->

    <script src="https://www.knotch-cdn.com/verification-pixel/latest/vpixel.js"
            data-kvpid="hfFQ-g--fmLy5DR+yWY/HH+lp+OMcXvjrHk="></script>
  </body>
</html>

#Technical Details

We designed the Verification Pixel with page performance in mind, and only send a single request after the page's document is fully loaded. Technically speaking, the request is triggered when the document's onLoad event is triggered. The Verification Pixel's JavaScript asset is built to be as small and simple as possible and only includes the bare essentials. This asset is served via our globally distributed CDN, which helps to minimize load times. Overall, our goal is to not impede your page performance.

Knotch explicitly does not share visitor identifiers between our Measurement product and the Verification Pixel, they are completely separate. Unique user identifiers generated by Verification Pixel integration are stored as first-party cookies. By design, Knotch is unable to track visitors across different domains, keeping results isolated.
