To test whether a conversion or segment pixel is implemented properly you will need to follow these steps.

Make sure you have a tool for browsing network traffic in your browser.

  • In Firefox go to Tools->Web Developer->Network
  • In Chrome go to Tools->Developer Tools. Then select the Network tab.

This will allow you to view every web request that happens as you browse a website, including the pixel requests.

The steps to take

  1. Go to the client's landing page and start the conversion process
  2. Once you have completed the final step look in the network traffic.
  3. filter by the word "adnxs" to reduce it to just AppNexus traffic.
  4. You should see an entry that looks like the screenshot below.
  5. If the number matches the pixel you gave the client, then they have implemented it correctly.
