Is this targeting possible?
A) target some or all of the people that have visited any of those pages (run ads to them elsewhere on the web, wherever they go)
B) target only users that have visited 2 or more of those sites (run ads to them elsewhere).
Is there an exchange or service where I can specify full URLs (or domains if necessary) and be able to target the visitors to those pages elsewhere on the web?
Thank you for your genius.
