I've been looking to try and find new outlets for our PPC and I came across these guys (Safe Shopping Network). They say they've been around since 2002 and get 6 million visitors a month... but I would of thought at 6 million a month I would have heard of them before. The also state they get an average Conversion rate of 5%. At the same time they have an Alexa rank of only around 120,000.
Do any of these things add up? They only want $0.12/click, but I am afraid of click fraud on sites I don't know about. Many thanks for any help you can give.
