In your experience, what do in cases when you are not sure if a certain website brings you genuine traffic? For example - some parked domain (domain name is a relevant niche keyword based) sends you 15 visitors a day... Do you suspect and exclude this domain? Or wait to see how it'll work in a long term? How long do you wait?
Hi Jul, there are so many "placements" on Google Display Network (GDN) that I'd go for the tactic "whenever in doubt - exclude". If you'll wait until each placement's cost passes your product's average ticket - you may go bankrupt on the way Sometimes I judge a placement according to the domain name and its general look. Parked domains are generally a no-no for me. What I think generally happens is that an advertiser spends a lot of money on GDN with poor results, and then just quits. Where there are a bunch of converting placements there is room for optimization.
