I'm working on a PPC campaign for a client who provides a luxury service. He has very little search volume in general, and there's one product that has no volume at all.
I'm wondering if it's worthwhile to run a campaign for this product using the general keywords. I estimate that 95% of the population has no intention of using our service and can't afford it even if they did.
For example, say we're a concierge doctor service. When people search for 'medical doctor' or 'medical treatment' they are looking for doctors, and we probably could help them, but they won't want us when they could go to the doctor's office down the street and pay a fraction of the price.
Obviously I'd tailor the keywords so it would be as relevant as possible.
Yay: If my ads are clear, then whoever clicks them is interested in my product, so my money is being well spent. I'll just have a very low CTR.
Nay: Spend the money on advertisement tailored to the target market, both people with existing interest, and those who would want it if they knew we existed.
Yay or nay?
