Hello friends- I have a unique niche product that people don't search for, because they don't know that it exists. However, it has done well with viral marketing. It was picked up by a niche blog and traffic exploded and we made some nice sales. When surfers see it, they buy it. I plan to continue the viral route, but want to try PPC as well. So, I just set up a PPC campaign and chose a number of niche sites that are surfed by users of my particular product. I chose PPC this time, rather than CPM, to test the waters. Question: How do I tell if my ads trigger? I have no idea what the other advertisers are paying on those niche sites, and dont want to bid too high. Is there any way to tell? Thanks for any insight- RR
