I know the guy who asked and he asked perfectly:
“…….would you like to be interviewed on xxxxxxxxx sometime? It’ll be good for your ego, you’ll get free backlinks, and you’ll get extra fame!”
He’s asked me what behaviour he wants (an interview) and told me what I’ll get in return. I’m pretty sure he was only kidding about the ego bit!
But the point is this, when you’re trying to make any sort of sale (get an interview, a date, money off a customer, etc) you need to make your offer and tell them what the benefit is to them if they ‘buy’.
Always remember, the key is that the benefit you offer must be wanted by the person – the benefit you provide needs to outweigh the risk/downside of buying from you.
