Fire tag only once per visitor?

[andrea_kebalo]

I have implemented a Facebook Tag that I want to trigger when a user watches three video views, and only fire the first time this happens. I have the '3 video view' restriction in, but how do I make sure that it only triggers once per each visitor?

You could set a cookie value when the 3 video view condition has been met and add an evaluation to the load rule for the cookie value to not be set.

@steve_thurner, thank you I'll give that a shot!

@steve_thurner, my "hook" for the 3 video view condition lives in a custom javascript extension so there isn't an explicit UDO variable that is set for 3 video views. 

Ideally, I'd like to set this cookie once my tag triggers, but I don't see a clear way to do that. 

What's my best course of action?

@andrea_kebalo in you hook code that fires the tag add code to drop the cookie:

document.cookie="videoviews=thirdvideo; expires=Thu, 18 Dec 2013 12:00:00 UTC; path=/";

Then set up videoviews as a cookie parameter in the data layer:

Finally add a load rule like:

This isn't the only solution, but it should work.

Thanks,
