Hello, please how do I run RON on trafficvance?
Seems like it is asking me to add keywords before I can save the campaign.
Gladly appreciate any help! 
RON on trafficvance is not possible and honestly said absolutely stupid. you would target any domain and keyword of the world and you would loose thousands of dollars in seconds.
just put for example facebook.com or amazon.com as a keyword and you have traffic like hell and will loose your ass fast :-)
with PPV traffic you can target any keyword and domain.
Yes, that will work. But probably only for tech support haha. Everything else, you better use some targets.
Trafficvance has millions of installs even in US. You would need tons of papers.
Ask your AM at trafficvance for a top targets list and an unsold inventory list.
You could add the top 100 or 1000 or whatever from either list and basically have RON traffic.
