Hey John,

One more thing before I start up my ads again. 

I'm wondering how significant it is what the pixel on my website remembers in terms of who has been converting. The reason I ask is because I reckon about half of my subscribers I got when I ran the ad without the confirmed opt-in on, so lots of secondary emails. Is this a concern in terms of fb optimising for the same kinds of people again / do I need to do anything about it?

I'm also wondering whether I should duplicate the squeeze page or change the slug for the new campaign as I believe the pixel remembers how particular squeeze pages have performed /who was converting ?

I'm still a bit vague about how the pixel works and whether actually it isn't that significant as long as I start a new campaign each time ?

Thanks !

Karen
