Why is that?
Maybe 'no way' is too strong. They could count clicks from the PDF, if it had links. If the PDF ad campaigns was the only one they had going, they could consider increased sales.
But in my (non-advertising-trained) view, this is similar to buying space on a billboard. Obviously, there is value in this, but it's really hard to measure.
I'm comparing this to a Google ad campaign, where you can fairly precisely measure your ROI for any given ad.
I don't want to sound too negative here - I want to sell the space. I just don't know how to create a 'value proposition' for an advertiser.
