How do you know when to place a secure pixel and when to place a non-secure pixel? First of all, let's define what each one is.
Non-secure pixel - A pixel that uses standard 'http' protocol:
Secure Pixel - A pixel that uses 'https' protocol:
*Note - In order to use a secure pixel, your tracking domain must have an SSL certificate installed with LinkTrust. Contact Support about setting up a secure tracking domain.
A secure pixel can be placed on any page and function normally. It is specifically designed for secure pages that have an active SSL (Secure Sockets Layer). An SSL is a way to create a secure connection between a page and the server where it is sending the information.
When we put https on the front of a pixel we are telling a secure page it is okay to fire the pixel because it is using the same protocol. If a pixel with just http is placed on a secure page the page may block the firing of the pixel because it only allows https protocol.
Generating a Secure Pixel
A pixel in LinkTrust is automatically generated as a standard http pixel. All you need to do is to add an 's' after the 'http' before you place the pixel or before you send it to your advertiser and the pixel will then be able to function on a secure page.
Placing An Affiliate's Pixels
If the LinkTrust conversion pixel you have placed is secure (using 'https' protocol) then any affiliate's pixel you have placed will also be required to use 'https' in order to fire in conjunction with the secure conversion pixel.
When firing a server to server pixel it does not matter if it is 'http' or 'https'
You can require secure pixels in the Pixel submenu of the campaign.
