I want to retarget people who have visited a section on a site. It is a very big site and I am positive I have had around 10k visits on that section. Both from organic clicks and paid clicks from FB. However, in audience manager I only see the size as being 460 for search and around 1200 for display. What does this indicate? I did set page-exactly matches in google analytics and I let it populate for around 10 days already.
