From your guys experience does the content network take awhile to start sending heavy traffic? I mean does it generally start out not sending that much traffic then after a few weeks it start picking up dramatically?
It normally doesn't seem to take a few weeks, but it does take about 24 hours some times to completely propagate or whatever they do behind the scenes.
Well, I've been signed up using Adwords for a few years, but each Adgroup seems to take at awhile to get rolling, as mentioned.
i usually use content network for branding or to bring tons of traffic. the best thing is to analyze the content traffic lots and lots then pick the good traffic and use placements only.
