In a new role, found majority of clicks are coming from G content network, but only few clicks result in genuine enquiries. In the past I checked the sites our ads were being displayed on and they were a mix or "almost p o r n, gambling and affiliate pages. Not where I wanted our reputation to be linked.
I prefer our ads are shown on G properties only, but I guess we will face a hit in traffic if I close down content network.
Would be interested to hear your thoughts?
