Most of the inventory is news websites, if you have the kind of ICP who hang out on news websites then you can plan on running something.
Just one way you could use it is by bringing Top-of-funnel traffic from here (the segments are unique in some cases) and then eventually converting them on some other platform like Google. or Linkedin via retargeting.
Note: My experiments are very limited, look forward to learning here how it turned out for others.
