Existing users can purchase with one click inside Step 4 in the member's area. If you're already a member, you can log in here.
Everyone else can access member's area at the link above for free and purchase access at Step 0.
You will then have access to the member's area to the instructions for activation. It involves giving access approval to Zontracker for your Amazon and Facebook accounts (only if you didn't do this already for other Zontracker features), and choosing which pixel option you would like. No other action is necessary. Zontracker activates the settings within 24-48 hours from the time of submission of details
After that, you will see the new FB pixel in your account (or merged pixel) when you are creating ads.
